✅ How to remove the Priora heater motor without air conditioning

Removing the Priora heater fan

You will need to : remove the throttle assembly and move it to the side, remove the frill and sound insulation of the engine shield.
Prepare a Phillips and flathead screwdriver. Procedure :

Bend the end of the brake pedal bracket upward.
Unfasten and cut the clamp securing the heater fan wire block.
Disconnect the block with wires from the heater fan by pressing the lock.

Disconnect the block with wires from the additional resistor. Then unscrew the self-tapping screw and nuts securing the heater so that you can move it forward (see “Removing the heater heater”).
Disconnect the fan ventilation hose from the nozzle.
Unscrew the 3 self-tapping screws securing the heater fan using a Phillips screwdriver.
Remove the Priora heater fan together with the impeller from the heater housing by prying it off the flange with a flat-head screwdriver.

The fan flange is attached to the heater through rubber pads. To replace them, remove the plastic bushings and then remove the cushions from the holes in the fan flange.

How to remove the Priora stove fan

If the Priora stove is noisy not due to debris in the impeller area, you will have to dismantle the latter in order to repair or replace it. Usually the cause of noise is a bearing failure, but sometimes collapsed impeller blades can make noise.

To dismantle the impeller you will need a Phillips and flathead screwdriver and a knife.

The procedure is as follows:

remove the throttle assembly, but do not disconnect it, but move it to the side;
remove the sound insulation of the engine shield and frill;
bend up the end of the brake pedal mounting bracket;
remove the clamp securing the fan wire block (the easiest way is to cut it);
release the pad lock and disconnect it from the fan;
disconnect the wires from the heater resistor;
Unscrew the self-tapping screw securing the stove mount;
disconnect the fan hose;
unscrew the 3 screws holding the stove;

remove the stove fan by prying it off the flange with a flat screwdriver.

Installing a Priora interior fan

The catalog number of the electric heater fan of the Priora is 2111-8118020. When installing the fan, turn it so that its branch pipe is opposite the motor ventilation hose. The rest of the assembly is done in reverse order.

By the way, if after replacing the heater fan there is poor air flow into the cabin, then try replacing the cabin filter.

Replacing the stove fan on a Priora

Welcome! Heater fan - thanks to it, air is sent from the environment into the car interior, but it comes from the environment cold, and after it flies into the instrument panel, it passes through the heater radiator (heating radiator, it is correctly called) which can either be very heated , or be too cold (This depends on how the coolant has warmed up, if it has reached its cherished operating temperature of 95 degrees, aiming, then the radiator also heats up very well and all the air passing through it becomes just as warm), that is, simple In other words, a fan is needed for only one purpose: to suck in air from the environment and release it in a certain flow into the car’s interior, where it, after passing through the radiator of the stove, heats up well and comes out warm into the interior.

Note! To replace the stove fan, it will not take very much but also not very little time (Here it still depends on which way you go), strength and tools, the main ones being: All kinds of wrenches, from wrenches to wrenches with socket heads, in addition to this set of various types of screwdrivers you will need and, of course, a new stove fan itself!

Summary:

Where is the heater fan located? It is located under the right side of the windshield if you look in the direction of travel of the car; next to it there is also a cabin filter which is located periodically every 15,000 thousand kilometers, or better even once every 10,000 thousand kilometers, it is recommended to change it to a new one, because when the filter becomes clogged, firstly (If it is a carbon filter) at a certain time, desorption occurs (This is a process in which all the dirt that has accumulated on the filter comes out of it, and when leaving it, it flies straight into the car interior, and the filter collects far from being pleasant things, dust firstly and toxic exhaust gases secondly, we think this will be enough for you to start changing this filter on your car more often and not delay replacing it), but this is not what this article is about We are talking about the location of the heater fan, for clarity, by the way, in the photo below it is indicated with a red arrow, and the blue one shows the same cabin filter that is periodically recommended to be changed on the car.

When should you change your furnace fan? If the fan completely fails, the stove stops working altogether (That is, when you turn the knob of the stove regulator, it will not turn on), if the fan partially fails (And partial failure may include breakage of the blades, the fan motor itself is acting up, etc. .d.) the stove will still work, but during its operation extraneous noises will be heard, such as rustling, humming, whistling, in addition to this, the stove may also work worse and weaker, these will be the most basic symptoms that will appear with partial or complete the stove fan fails.

Note! If the heater stops turning on, don’t run to the auto shop to get the fan right away, you’ll need to check everything first, and the first thing you need to check is the fuse that goes to the heater (the heater goes to fuse F9 with a current of 25 Amps), if it’s intact then most likely this fan has failed, because only the fuse and this fan are responsible for the operation of the stove (In some cases, there is also a problem with the wiring, and therefore the fan does not turn on) and they wanted to add something else about the low flow air, it can be not only due to the fan, but due to a very clogged cabin filter, for example!

How to change the heater radiator on a Lada Priora

In fact, every motorist who owns a Russian vehicle discovers a malfunction of the car’s heating unit specifically in winter. After all, only with the advent of severe cold does a person begin to think about how to avoid freezing while driving a car. Naturally, everyone uses a stove for this. But what should those for whom this same device does not work properly do? After all, only the heater is able to ensure that the normal temperature is maintained in the cabin, allowing for comfortable movement. In this article we will look at only one reason why the heating device stops working, we will learn about the principles of repairing and replacing the heater radiator installed in a Lada Priora car.

If the motorist is sure that the heater core needs to be replaced, it may take a lot of time to remove the faulty object, because most likely, in the process it will be necessary to change not just a blown fuse, but to carry out more serious repair work. True, one should not immediately despair because of one’s own ignorance; the material contains a carefully written annotation that helps everyone understand how to replace the stove radiator in a Priora with and without air conditioning.

Replacing the radiator of a heating unit in a Priora that is not equipped with air conditioning

Replacing the heater radiator on a Priora without air conditioning may make sense in this case if warm air does not begin to flow into the cabin, while the heater itself is working. If, in addition to the above dilemma, there is also a water leak from under the Priora stove, the motorist will have to urgently remove the poorly functioning unit in order to solder the latter. From time to time, repairs are impractical and you have to replace the old device with a new one.

So, first, you need to start by removing the negative terminal from the battery. The fact is that the issue here is not only about the safety of the master himself, but also about additional insurance, which allows him to avoid several nasty surprises that, if handled carelessly, can appear not only with wiring, but also with electrical equipment.

If you are replacing the heater radiator on a Priora without air conditioning, after de-energizing the system, you can begin to dismantle the windshield trim. At the same time, you should also remove the wiper arms, which can cause further discomfort during operation. After that, you should free the unit from all plastic tubes, through which the liquid located in the windshield washer reservoir goes directly to the nozzles. Only after all the above steps have been carried out will it be possible to remove the decorative trim located on the sides of the windshield. In fact, performing such a manipulation is simple - just get rid of 7 screws.

Replacing the heater radiator on a Priora can only be done after removing the hood seal. Before dismantling, it should be taken into account that there is a screw in the middle of the lining that tightens both halves of the structure. Using a screwdriver or any knife, you can carefully lift the plugs (this element serves as the “cover” of the screw) and unscrew them.

After which you can begin to remove the sound insulation, which is located in the unit compartment. To do everything well, you will have to unscrew the screws and remove the pads (there is no clear rule about which of them to remove first: left or right). Then you should get rid of the pipes that go directly to the radiator. A person who wants to figure out how to get to the heater radiator on a Priora must loosen the clamps holding the structure itself.

After which you can remove from the connectors all the wires going specifically to the stove. You can remove them using two keys, namely, the first “10”, and the other “8”. After unscrewing all four nuts, move the wiring harness to the side, which is held in place by the holder. The “13” key will help to dismantle the bracket located on the brake pedal. Only then can you begin to remove the heater radiator on a Priora that does not have air conditioning. An ordinary Phillips screwdriver will help to dismantle the device, allowing you to remove 3 screws. All the rest of the work consists of installing a new unit and reassembling the system in the reverse order of the described actions.

How to replace the heater fan on a VAZ 2170-VAZ 2172?

Note! When replacing the fan, if the cabin filter has not been replaced for a long time, then it can be removed and replaced with a new one, it doesn’t cost a lot of money in car dealerships, but just so you don’t have to get into the car (Still, to change the heater fan, you need to go to that place choose where the filter is installed), you can immediately change it if it is too dirty and thereby drive in the near future with clean air in the car!

Removal: 1) There are two ways by which you can remove the stove fan, we will tell you both, but before we start describing them, let’s talk about them briefly, and which one you will use during the work is up to you to decide, the first method is in removing the throttle assembly, in removing the front panel upholstery and in removing the cooling expansion tank, the second method does not imply this; when choosing the second method, you will only need to unscrew the screws and nuts securing the fan and then remove it from the car.

Replacing a radiator heater on a Lada Priora (with or without air conditioning)

One of the reasons for poor heater performance is the furnace radiator . While the vehicle is in use, it begins to leak and can no longer provide the required amount of heat to the cabin. Depending on the year of manufacture and the complete set of Lada Priora, the process of removing the oven (radiator) can be very different.

How to remove a stove radiator on Priorat without air conditioning

Since the start of production, AvtoVAZ has installed a heater from the Top 10 on the Priora (catalog number: 21110-8101012). The disadvantage of this design was that the heater radiator was removed in the direction of the vacuum brake booster, which allows. As a result, the heater assembly must be removed.

The procedure looks like this:

Remove the windshield wiper blades.
Remove the protection (windshield).
Remove the sound insulation from the engine shield.
Disconnect the stack of connectors with wires.
Unscrew the heater mount.
Divide the heater into two parts (left and right).
Remove the right side of the heater (in the direction of travel).
Move the left side out of the way to gain access to the furnace radiator.
Drain the antifreeze.

There is another way to replace it. To gain access to the furnace radiator, it is necessary to remove the vacuum brake booster along with the brake pedal instead of the heater housing. This allows access to the left side of the heater (in the direction of travel) and to the radiator itself.

Replacing the heater radiator with Prior for air conditioning

After some time, the manufacturer began to equip its cars with air conditioners (for example, HALLA or Panasonic (Ref: 21703-8101012). The design of the new Priora heater has become much more convenient in terms of maintenance. Now you do not need to remove the can, wiper blades, heater or vacuum brake booster for replacing the hob.

All you need to do is remove the engine shield noise shield, remove the air filter hose, the engine seal and the heater radiator . All! We drain the antifreeze and remove the radiator towards ourselves, towards the engine.

Video instructions are attached:

So, replacing the stove radiator. Priorities depend not only on the type of insulation, but also on the chosen method of replacing it. And how did you shoot the heater radiator in your car? Which method suits you best? Let us remind you that solutions to other problems with plates can be found in this article.

Removing the heater fan on a Priora is difficult, but possible.

Remove the right side of the engine compartment bulkhead trim. The heater fan motor is visible, but you can’t get to it: the outer plastic casing of the air conditioning unit is in the way and can only be removed by dismantling the entire air conditioning unit assembly (draining the antifreeze, removing the vacuum brake booster, draining freon from the air conditioning system, etc.).

We make a cut on this casing in the indicated place, which will make it possible to remove the right side of the casing and get to the heater fan

The heater motor is in our hands.

Lada Priora Hatchback KosmosS › Logbook › Replacing the heater motor with Panasonic air conditioner

I drove for the last month and suffered with my air conditioning.

The symptoms were bleak; the air conditioner either worked or didn’t.

In other words, the air conditioner worked properly, but the heater motor

He was obviously shirking his own work.

Especially when you drive on smooth Russian roads))

Symptoms: the motor refuses to operate in all positions of the rotation speed control handle.

At first there were floating speeds, later it completely died out, and from time to time it came to life on bumps.

I thought there was a bad contact in the connector. I got to the connector, everything is ok.

If you lightly hit the fan body, it comes to life and continues to work normally, which means the reason is in the motor itself, and not in the control unit or connector contacts

I was completely fed up with this and now I dared to change it...

It turns out this is very difficult to do and spare parts

you need the original. Panasonic ept)))

To be honest, it got me, it’s either the original regulator or the motor (((

But I did it even simpler))

Naturally, my hand didn’t rise to shred and cut my car, but what can you do.

There is no way without this. Priora ept)) Thanks to AvtoVAZ for their foresight in the next repair. All that was necessary was to make the upper part of the heater in the area of the motor removable. But no, we are not looking for easy ways; the right way is to remove everything))

hacksaw blade . So that nothing would interfere with its removal. Cut only as shown in my photo so as not to disturb the rigidity of the entire casing. And it is this half that I cut off that only plays the role of an anther.

But this turned out to be not enough... The motor rested against the place where the engine mount was mounted on the glass. This was done specifically so that no one could remove the motor in this way without completely disassembling the heater. But we move on))

In general, we cut the fan casing itself, but so that the 2 motor fasteners are outside the cut (this will not affect its rigidity). You can see in the photo where to cut.

Well, now that the engine is in front of us, we see its Chinese origin and the savory price for it. But in terms of mounting, it is completely identical to the 10 Mu and Kalinovsky. It only differs in the location of the breather, but this is not a hindrance for us.

We put the motor in place and check everything works. This means we can assemble it.

I then coated the incision sites with Poxypol and everything was fine. The integrity was not compromised and the appearance was not damaged at all; it is not visible there.

But it made it easier for me to disassemble and maintain this unit in the future.

Replacing the heater radiator on a Lada Priora (with and without air conditioning)

One of the reasons for poor heater operation is the heater radiator .
During the operation of the car, it begins to leak and is no longer able to transfer the required amount of heat to the interior. Depending on the year of manufacture and configuration of the Lada Priora, the process of removing the stove (radiator) can vary greatly.

How to remove the heater fan on a Priora with Halla air conditioning

Maybe it will be useful to someone.
I was able to remove the motor without dismantling the entire system. We remove the trim from the hood side, and then everything will become clear. You need to unscrew 3 screws, thereby separating the motor housing from the system housing. We take it out as much as possible. We see that the butt of the motor will rest against the engine support. Now. The motor has its own plastic casing (which makes the motor larger). We remove it by snapping off the tabs, there are 3 or 4 of them, I don’t remember. All this must be done carefully! There are definitely no such exclusive spare parts on sale! Removed. Now the motor has become shorter, due to which it began to protrude more, the impeller comes out of its hollow :biggrin: by 2/3. Then I freed all the air conditioning pipes from their attachment to the body. They became more mobile. Yes, they are also very annoying! They will also have to be moved. Now we try to remove the motor with the impeller from the system housing. It can be seen that the body of this system very tightly describes the circumference of the impeller, which is why problems are created when dismantling/installing the motor. We twist it, move it in different directions, you can tighten the impeller somewhere - it is a little flexible. In general, I have to get out! The installation of this problem back deserves a separate story! We need another pair of hands from the glove compartment! In the same way: We twist it, move it in different directions, you can tighten the impeller somewhere. put it back in.

Inserted. Now the real thing begins. oops in this process! Remember that same casing that snaps onto the motor? From the side of the glove compartment, an assistant (it is advisable that he has thinner hands and strong fingers!) sticks his hand in a zigzag and presses his fingers against the impeller with all his strength. The other one also puts on the casing with force. It sits very tightly on the latches, dog! If all this was successful, then you are a happy person who did not have to remove the entire system! Thanks for the good advice. Because according to the factory instructions, in order to get to the heater fan, you need to drain the antifreeze, bleed the gas from the air conditioner (I have a Panasonic), and only then remove the heater assembly.

I repeat, this is what it says in the heater repair instructions. At a service center, such a procedure for replacing a fan motor will cost about 30 kilorubles, and maybe even more, because they won’t deal with stuck brushes; they’ll do a unit repair. And you can do it on your own in half a day. It is sawed with a simple saw blade, and during assembly the gap is sealed with ordinary auto sealant, but not vinegar-based. The heater on most cars is made in such a way that to get to its guts, you need to disassemble the floor of the car.

How to remove the heater radiator on a Priora without air conditioning

Since the beginning of production, AvtoVAZ has installed a heater from the “ten” on the Priora (catalog number: 21110-8101012).

How to repair a heater gearmotor on a Lada Priora

Hyundai Accent silver Logbook Replacing the heater fan

It is known that there is only one result of failure of the heater micromotor: it is not possible to change the position of the damper, as a result of which only cold or only warm air enters the cabin. In this case, the reasons for the breakdown of the device itself can be both external and internal. The first includes a break in the engine power supply circuit and the occurrence of an error in the heater control unit. It is perhaps best to entrust the troubleshooting of these problems to a specialist. As for internal breakdowns, such as mechanical damage to a plastic gear or a malfunction of the micromotor of the Priora heater damper gearbox, in some cases you can deal with them yourself. The sequence of actions is as follows:

Before disassembling the gearmotor, remove the plastic adapter from the shaft, which operates the same heater damper.
Next, disconnect the two parts of the plastic body of the device by acting on the fasteners with a flat-head screwdriver (sometimes you have to use two screwdrivers at once). Disconnect the halves of the housing, removing one of them from the motor shaft, as carefully as possible so as not to lose small parts that fall out.
You will see a micromotor and plastic gears - inspect them externally for broken teeth. It should be noted that the working stroke of the gears does not exceed 45 degrees. Therefore, if several teeth are missing on one of them, the problem is eliminated by turning the gear. If damage is noticed on a sector (a wheel with an incomplete circle), then in order to rotate it to the desired angle, the metal shaft will have to be heated with a burner or on a gas stove. By the way, for normal operation of this sector it is enough to have only nine whole teeth.
If upon inspection it turns out that all the gears are operational, then the problem lies in the failure of the electric motor. First, you should check whether power is supplied to it - to do this, connect a regular Krona battery to the motor contacts. If it works, then the cause of the malfunction is external, otherwise you will have to disassemble the micromotor.
From the side where the wires are connected, straighten the housing where it is fixed, after which you can remove the insides of the engine. To do this, press on the shaft and press it in. Now you can see the two brushes and the armature windings. Make sure that there are no traces of soot or melting on the windings. And also, often at the point of contact between the commutator and the brushes, carbon deposits form, preventing normal contact - the contamination should be removed.
Upon completion of the repair procedures, assemble the electric motor, test it using a Krona battery and assemble the gearmotor itself.

If, when disassembling and inspecting the internal structure of the motor, it is discovered that one of the armature windings is damaged, then repairing it will be impossible. In this situation, you will need to replace the Priora heater gearmotor.

Important! When handling the micromotor of the gearbox, you need to be as careful and careful as possible, since sudden movement or impact with too much force can lead to damage to its internal parts and further unsuitability for repair. Replacing the Priora heater damper gearmotor involves dismantling it and installing a new analogue

We described above in the article how to remove the device from the car. As for the installation of a pre-purchased micromotor gearbox, it is performed in the reverse order of removal

Replacing the heater radiator on a Priora with air conditioning

After some time, the manufacturer began to equip its cars with air conditioning (climate control), for example, HALLA or Panasonic (article: 21703-8101012). The design of the new Priora heater from a maintenance point of view turned out to be much more convenient. Now, to replace the stove, you do not need to dismantle the frill, windshield wipers, heater or vacuum brake booster.

It is only necessary to: remove the sound insulation of the engine shield, remove the engine air filter hose and the seal in the area of the heater radiator hoses . All! Drain the antifreeze and remove the radiator towards you, towards the engine.

Video instructions are attached:

Thus, replacing the radiator of a Priora stove depends not only on the type of heater, but also on the chosen method of replacing it. How did you remove the heater radiator on your car? Which method suits you best? Let us remind you that solutions to other problems with the stove can be found in this article.

The heater of modern cars operates quite quietly, without creating discomfort for the driver and passengers. If, when you turn on the fan, extraneous noise appears: crackling, squeaking or rustling, you need to fix the problem at a service station or yourself. What to do if the Priora stove is noisy?

Life hack: gear motor and other components of the Priora car heater

If the windshield of a Lada Priora car is fogged up and looks as if it was smeared with greasy hands after eating pirazhki - driver, beware, your heater is leaking! Maintaining normal temperature in the cabin at different times of the year is necessary in order to feel comfortable behind the wheel. In winter, the stove on the Priora saves you from freezing, which provides the heat a person needs. But you need to take care of it and prepare it for winter in the summer, because being left without heating in winter is not the greatest pleasure. The sore spots in the system that break down more often than others are the gear motor and the heater damper. Priora is a warm car - the original DAAZ is very good, it warms, and is warm in winter, because its radiator has the correct structure and fluid circulates inside. If you install the Chinese Luzar, you will freeze at -20 - I checked it personally. I put this luzar on, then took it off. The heater radiator is available for cars with and without air conditioning. The structure of the node is slightly different.

The stove block of the Priora car is indicated below in the figure. As you can see, in addition to the block, the entire assembly consists of many spare parts. On the Priora, the stove has a conventional design - having taken the time to diagnose, you need to completely check the entire system in order to make an “investment” in the future - in winter you will need to look for a heated garage for repairs. If the Priora blows cold air or does not heat well, these are signs that something is wrong inside, and this malfunction needs to be sorted out.

Operating principle of the stove

The heater is controlled by a controller, from which a signal is received to turn on the stove. The driver sets the temperature in the cabin. If the temperature sensor detects that the temperature has dropped below the set level, the controller sends a signal to change the opening width of the stove damper. In some cases, an electronic failure occurs; instead of hot air, cold air is supplied.

The principle of operation of the stove - what it consists of on Priora, article numbers

For the VAZ-2170 restyling, two types of heaters were installed - with a Panasonic control controller or with an NSS control controller. The last type contains the following parts:

air recirculation damper gearmotor (21700-8127300-10);
Priora car heater fan (motor) (21700-8118020-10);
air filter (21700-8122090-00);
motor speed controller (2170-38127025-10);
heating system damper motor (21700-8127200-10);
heater radiator (21700-8101060-10);
outlet hose (21700-8101208-00);
outlet pipe (21700-8101200-10).

As for the second option from Panasonic, the device around the radiator of the heating system on the Priora is slightly different:

recirculation valve (21700-811908-00);
fan (stove motor) (21700-8118020-10; 21700-8118020-00);
vacuum hoses with check valve (21700-8119100-00);
solenoid valve (21700-8119130-00);
air filter (21700-8122020-00);
inlet pipe (21700-8101200-00);
damper gear motor (21700-8127200-00);
radiator temperature sensor (21700-8101250-00);
radiator (21700-8101060-00);
outlet hose (21700-810120800).

The pre-restyling car has a lot of parts from the “tens” - even the gearmotors are different. Much was inherited from the VAZ-2110, and the first cars before restyling were almost completely equipped with its heater. The assembled stove for the VAZ-2170 Priora pre-styling received catalog number 2111-8101012-10, a more updated version – 2170-81010-12. Price from 5500 rubles.

The device is as follows:

air flow reducer (2170-81271-00);
air temperature sensor (inside the car) (11186-81280-50);
control unit (switches that are built into the central console to set operating modes) (21703-81880-20);
resistor for setting the motor speed (2123-81180-22);
heater motor (2111-81180-20);
damper gear motor (2110-81272-00);
air filter (2110-81220-20);
radiator (2110-81010-60).

The heating radiator of the Priora car can operate in two modes: automatic and manual.

The manual mode is performed when a person independently sets the desired temperature in the cabin on the control unit.
The automatic mode operates almost constantly - the required and actual air temperature is checked and the control controller issues a command to change the damper angle, supply hot or cold air to bring the temperature to the set level.

When the driver adjusts the settings on the control unit, the resistor sends a signal with the necessary data to the motor. The fan can produce maximum power, although the resistor will not be used to its maximum. The same process with the direction of air - the driver sets it, and the gearmotor sets the desired position of the damper.

By its principle, the heating device “lies next to” the engine cooling system. When the driver turns it on, the heater tap opens, and hot coolant moves through the pipes, which passes through the radiator of the Priora car’s heater and returns back. This increases the distance over which the coolant circulates.

Therefore, turning on the heating is one of the ways to cool the engine. It will really become hot in the cabin, because all the heat will be directed there, and the engine will give off this heat more and more, the temperature of the coolant will drop.

Malfunctions

For normal operation, the heating system needs: tightness, integrity of parts and normal antifreeze. The first step is to check the relay and fuse - after all, this unit contains electrical appliances inside. If the unit's electrical network is not in contact with the ECU, there is no point in turning the controls on the heater control unit.

The heater fuse on Priora has the number F9. In order to get to it, you need to remove the plastic plug above the driver's left knee (under the headlight switch) by unscrewing three bolts around its perimeter.

Once the fuse has been inspected and no deficiencies have been identified, further diagnostics can begin.

Perhaps the most annoying thing in any car is the situation when, even at the hottest summer temperatures, the heater does not turn off. This happens because the damper does not block the air flow. The heater damper on the Priora is controlled by a gear motor, which stops after its operating life has expired - it will have to be replaced.

While driving a VAZ-2170, you should carefully look and listen to what you see and feel. If heat should come from the cracks, but it doesn’t, then something is wrong with the seal or the damper gear motor. For example, if the glass becomes greasy, as if it was smeared with your hands, it means that the heater radiator is leaking. However, these are not the only signs of a heater failure.

Priora: the stove blows cold air, does not heat - reasons

When cold air comes from the heating system and turns into the air conditioner, the following possible malfunctions are considered:

The heater hoses do not supply coolant, or the radiator itself is not efficient enough and does not take heat from them.
The air filter is dirty. If there is no new part nearby, try removing the filter and then starting the heating system without it.
The damper gear motor is stuck.
The control unit (switches) is broken.
The temperature sensor in the cabin has broken (it is located under the roof).

The shutter does not move, and the modes: face, legs, glass do not work

Reasons for this problem include:

Faulty air distribution gearmotor.
Inoperative control controller (CU).

The stove blows hot air when turned off.

The most likely reason for this behavior of the heater is a failed damper gear motor.

It’s noisy – what to watch

When you hear an unknown noise, you need to check the heater motor bearing. The noise is caused not so much by the bearing, but by small debris that has gotten under the motor blade.

The stove does not blow and does not even turn on

There are only two reasons why air does not escape from the heating system of a Lada Priora car. When the interior heating does not work, you need to check fuse F9 and the switches on the center console - perhaps they are simply broken.

Replacement: how to remove (change) the stove on a Priora with and without air conditioning

Replacing a stove completely is rarely done; components are mostly changed. Often the main reason for disassembling the heater on a Priora car is replacing the heater radiator. When it ceases to be airtight and no longer works as efficiently, it is necessary to begin repairs. In order to remove the heater on a Priora car without air conditioning, you will need a set of wrenches (socket and socket wrenches) and a Phillips screwdriver. As the system is disassembled, it is worth inspecting all parts and replacing worn ones. Perform the work according to the instructions:

Remove the negative from the battery.
Remove the lower windshield seals and engine sound insulation.
Loosen the clamps that hold the pipes adjacent to the heater core, and then disconnect them. First place a basin under the pipes to drain the coolant. After the liquid has poured out, cover the pipes with a rag.
Start wiring. Unclip the latch and disconnect the motor wires. Then de-energize the additional resistor.
The wires that go to the damper drive motor are secured with a clamp. You need to bite it and then disconnect the wire.
Next, we proceed to dismantling the heater itself. Take a “ten” socket wrench, remove three screws with it, and remove another screw with an “8” wrench.
Next, move the wiring harness from the heater to the side (attached to a small bracket).
Now, from the passenger compartment under the dashboard, unscrew the third nuts securing the brake pedal with the “13” key, and then move it to the side.
Pull the block towards you.
Install a new heater instead of the old one if necessary.
When you are concerned that the heating is not blowing correctly - not in the required mode - you will have to check everything again during dismantling.
To remove the heater on a car with air conditioning, follow these steps:
Also remove the negative terminal, then the lower windshield seal, and the engine sound insulation.
Unscrew the screws covering the heater radiator.
Also carefully remove the pipes: the coolant must be drained into a prepared basin.
Slowly and smoothly pull the radiator up until it comes out of the mounts.
Install the new radiator in the reverse order.

Lada Priora has Panasonic or Halla air conditioners. They differ only in the fastening, so there will be no difficulties when replacing the heater radiator.

the stove is completely stuck!!! | Topic author: Jarrid

Good people, help! The stove fan does not blow at times! And now it’s winter, sometimes it’s impossible to travel...it’s cold(!!

Denis (Hildagard) look at the fuses, contacts, edge of the motor pi.da

Max (Makbul) Alexander, good day, if the stove does not blow at all at times, not at any speed, but sometimes turns on, you need to clean the motor, the brushes have poor adhesion to the rotor, and if it only works on four, then the resistance needs to be replaced. I suffered for a long time myself, is Kander standing on it?

Nikolay (Aubeline) there was such a piece of crap, it doesn’t work turning on the heater speed sometimes + windshield wiper and heater, replaced the relay everything is fine

Sergey (Jerica) I had the same situation: sometimes when starting the car the heater did not turn on, you started driving and it turned on. I changed the heater fan and everything is ok!

Alexander (Raheem) Max, thank you! Yes, the Conder is worth it! Is it difficult to remove the stove?

Volodya (Paolo) if you are with a conder you will suffer

Max (Makbul) Alexander, there’s nothing complicated, half an hour of dancing with a tambourine, you get to the motor, remove the grille, frill, insulation, then you will need to saw off the air intake casing to the right of the motor, remove it, unscrew the motor itself, three screws, pull the motor out a little, it pulls out it’s tight because it sits on rubber bushings, all that remains is to remove the volute, unscrew two screws on the volute, one on top of the other on the left side, and also saw the volute to the right of the upper screw, to the right in order to maintain the rigidity and tightness of the structure. The bottom also needs to be sawed, but I didn’t saw, it’s not very convenient, when I pulled it back, it broke off on its own where it was needed. you pull out the motor. It took me 20 minutes to do everything. When assembling, I covered the cuts with black plasticine.

Max (Makbul) autolada.ru/viewtopic.php… read it, there is a photo there.

Max (Makbul) you can also type into the search engine “the heater motor of the Lada Priora station wagon is dying”

Max (Makbul) Sergey, you could just clean the old motor and that’s all. at no cost.

Alexander (Raheem) Max, thank you very much! I will try!

Max (Makbul) please contact me :))

Seryoga (Gaddiel) Max, hello. The stove only works at speed 4. Changing the resistance did not help. There is a condenser.

Max (Makbul) Seryoga, Kander Panasonic? Either the resistor is faulty, or the speed controller is faulty. Maybe the motor is already tight, the resistance is immediately burning. For prevention, when you start the car, immediately put the heater on four, the motor will work past the resistance, turn it and you can reduce the speed, this is what the resistance is for. on Panasonic it costs 4500. It’s like 800, it’s expensive to change. Do the motors stop on the 4?

Sergey (Jerica) Hello Sanya. I recently had a similar problem, as well as a friend. The root of the evil is in the fan chip, it just doesn’t fit tightly. Turn on the stove and try to move it. It’s just difficult to crawl up if the air conditioner is included in the package.

Alexander (Raheem) Sergey, thank you, I installed a new stove!

Vanek (Shirlee) guys, help out, the stove doesn’t react at all to cold, i.e. it’s running hot. What should I do?

Konstantin (Lorne) Hello, tell me the Priora is 11 years old, the stove was working, stopped, started the stove, it doesn’t make noise, the air conditioner is not so hot... it doesn’t blow at full speed, the air conditioner is the same, even the light on the air conditioner regulator does not light up... the motor can be heard but hums very faintly? ? what could it be?

Sergey (Jerica) Kostya, hello. The whole problem is in the trick, cat. Connected directly to the fan under the windshield on the right. In order to get to it you need to remove the frill and wipers. Try to move it. Your hand will get through. Ideally, insert about three thin wire hairs into the chip itself. It will lock in. And it will stop “moving away” from the vibration. The chip melts while the stove is operating. The voltage on the stove fan is probably to blame. You can fix it yourself. The main thing is patience. Priora was collected by enemies. Where the hell are you going? That's why I bought a Skoda.
