How to disassemble the cigarette lighter on a Prior?

Reasons why the cigarette lighter does not work on Lada Priora

Over time, the unit may break and require repair. Why does the part fail? Among the common reasons why the Lada Priora cigarette lighter does not work.

1. Burnt out heating element. If you often have to connect high-voltage devices to the connector, such as a wheel compressor, the element itself can quickly fail and the fuse will trip.
2. Light bulb broken. There is a light around the hole that may stop working.
3. Oxidation or poor contact of the cigarette lighter. Over time, contact may be lost between the antennae of the part and the socket itself, as a result of which the element fails. To check this, you need to remove the fuse and then inspect it for oxides. Additionally, you should tighten the fastening antennae. The fuse is put in place.
4. The cigarette lighter connection wires have fallen off. Refers to “age-related diseases”. For inspection, you will need to remove the VAZ Priora cigarette lighter from its socket without touching the fuse. In the event of a malfunction, it is necessary to solder the fallen wires.
5. Inept tuning is also a cause of failure. Some owners buy low-quality splitters and load them to full capacity. This leads to increased load on the fuses. Promotes accelerated wear of the generator.
6. Blown fuse. A breakdown may occur due to a short circuit. To identify this fuse malfunction, you should connect the lamp to the connector. Then turn on the ignition. If it does not light up, then the reason is the fuse. The protective element needs to be replaced.

How to remove the cigarette lighter on a Priora yourself?

Even in a new car, after a short period of use, something can break. For example, the cigarette lighter or its backlight may fail. This type of breakdown especially occurs due to frequent use of the cigarette lighter. Nowadays, the cigarette lighter socket is used to connect devices such as a navigator, video recorder, vacuum cleaner, charging a laptop (phone), etc. to a power source. Therefore, it is not surprising that one of the first things to break in a car is the cigarette lighter or its component part. To determine the cause of the malfunction, it is necessary to dismantle it.

Possible causes of breakdowns

Before removing the cigarette lighter on a Priora, it is worth familiarizing yourself with the possible causes of its malfunction. Possibly to fix a problem. There is no need to remove the cigarette lighter.

If the cause of the breakdown is a fuse, then to replace it you need to remove the cover from the installation block and find the F13 mark - this is the fuse that is responsible for the cigarette lighter. Most often it can be removed without the help of an auxiliary key. Replace the blown fuse with a new one and replace the cover. The whole procedure takes no more than 10 minutes.

How to remove the cigarette lighter?

According to the instructions described in the Lada Priora repair and operation book, the cigarette lighter is replaced after removing the tunnel. And if you don’t have the necessary tools at hand, you’ll have to remove the seat. But there is a more simplified option, which few car owners know about. How to change the cigarette lighter on a Priora without dismantling the floor of the car?

Replacing the cigarette lighter on a Priora

Before any manipulations performed on the car, especially if they have to do with wiring, it is necessary to remove the terminals from the battery. Only after the car is de-energized can you begin to work.

To remove it, you will need to use a small flat-head screwdriver that is inserted into the hole inside the cigarette lighter. You need to press the screwdriver onto the latch (green) and turn the metal sleeve. Carefully remove the metal cigarette lighter cup by pulling it towards you. Once removed, the green plastic and wiring are separated from the cigarette lighter. Next, repairs are made, and then everything is put back together in reverse order.

If the cause of the breakdown is a burnt-out light bulb, it is necessary to dismantle the socket. When you press the filter lock, the entire structure is pulled out, after which the burnt out light bulb is removed and replaced with a new one. They assemble everything the same way, but in reverse order.

Replacing a cigarette lighter is not a complicated operation, and it is worth learning how to do it yourself. However, regular burnout indicates a problem with the wiring system, especially if it occurs without excessive loads. This fact cannot be ignored, since a short circuit can lead to serious consequences.

Connection diagram and node fuse

If the last problem occurs, you need to get to the shield located behind the front panel. Next, remove the plastic cover, gaining access to the fuse box itself. It is necessary to change the element numbered F13 - it is responsible for the cigarette lighter circuit.

Before doing this, you should pull out the connector going to the socket itself. To get to it, you will need to remove the decorative plastic from the front of the central tunnel. The connection diagram, as well as the pinout of the cigarette lighter and fuse are shown in the photo.

Serial number and part numbers

Before you begin repairing the cigarette lighter and disassembling the central tunnel, you need to buy a suitable spare part. There are different device options for the Lada Priora on sale, both original and not. Cigarette lighters from the AvtoVAZ factory have article number 21230-3725010-00.

When purchasing, you need to pay attention to the cost of the spare part. A cigarette lighter price that is too low indicates the use of low-quality materials. Such a part may burn out within several weeks after replacement. In addition, the item must be well packaged and have a certificate of conformity.

Device and how it works

The Lada Priora cigarette lighter is located in a standard place for domestic cars (VAZ, etc.) - in the central tunnel of the floor covering near the parking brake handle. The location in a visible place ensures ease of use of the device and accessibility of connecting wires from different devices. For comfortable use, the device is complemented by a backlight that turns on in the dark. The Priora 1 and 2 cigarette lighter designs differ in configuration and design, because... The nest is more compact than other VAZ models.

The design solution and operating principle of the cigarette lighter are standard. The cigarette lighter consists of a socket (a hollow cylinder made of alloy) and a metal socket. The cartridge is supplemented with a button, after pressing which the plus is connected to the minus by means of a spiral. The Priora brand cigarette lighter does not have a relay. The relay functions are performed using bimetallic elements built into the inner surface of the cartridge. After heating, the elements unclench, the spring presses on the cartridge, placing it in its original position.

How to change the cigarette lighter fuse

Knowing where the cigarette lighter fuse is located on the Priora, you can replace it without any problems. Service in auto repair shops is now quite expensive, so let’s figure out how you can do it yourself.

The most important condition is that you cannot install any home-made devices, such as, for example, wire or a paper clip, instead of the fuse. In addition, it is better to use domestically produced protective elements and not buy Chinese analogues, as they are of low quality. None of this is safe and can even lead to a fire.

Fuses and relays in Lada Priora, electrical diagrams

Lada Priora is another car in the line of new VAZ cars, which is gaining popularity among segments of the population. External similarities with the 10th model attract the attention of young people; the relatively low price is also a reason for purchase for most car enthusiasts. Along with the growth in popularity, the owners of this model are gaining experience in repair and maintenance, which is becoming more and more every year.

If your Priora has electrical problems, do not rush to get upset; first, check the fuses and relays in your Lada Priora. These are the ones that will be discussed in this article.

Fuse box in the passenger compartment of VAZ-2170, -2171, -2172

The fuse box in Priora is located at the bottom of the dashboard, on the left side of the steering wheel. To get to it, you need to open the cover, which is held on by three latches. Rotate each locking knob 90 degrees and pull the lid down and it will snap open.

Fuses in the interior mounting block

F1 (25 A) - radiator cooling fan . If your fan does not work, check its motor by applying 12 V directly to it from the battery. If the engine is working properly, then most likely the problem is in the wiring or connectors. Check the serviceability of relay K1.

The fan in the Priora usually turns on at a temperature of 105-110 degrees. Do not allow the engine to overheat, watch the arrow of the temperature sensor.

If the fan runs constantly and does not turn off, check the coolant temperature sensor located on the thermostat. If you remove the connector from the working sensor, the fan should turn on. Check the wiring to this temperature sensor, as well as the contacts of relay K1, move this relay, clean the contacts. If this is the case, replace it with a new relay.

F2 (25 A) - heated rear window . Check together with fuse F11 and relay K2. If the rear window does not fog up, the heating element threads may have broken. Inspect all the threads and if you find a break, seal it with special glue or varnish, which can be bought at car dealerships for 200-300 rubles. Check the connection contacts at the terminals to the heating elements at the edges of the glass, as well as the switch on the dashboard and the wiring from it to the rear window.

F3 (10 A) - high beam, right headlight . F4 (10 A) - high beam, left headlight . If the headlights do not shine on high beam, check the K7 relay and the headlight bulbs. The steering column switch, wiring or connectors may also be faulty.

F5 (10 A) - sound signal.

If the signal does not work when you press the steering wheel button, check relay K8. The signal itself is located under the radiator grille; you can get to it by removing the plastic casing from above. Check it by connecting the voltage to 12 V. If it doesn’t work, try turning the adjusting screw, or replace it with a new one.

F6 (7.5 A) - low beam, left headlight . F7 (7.5 A) - low beam, right headlight . When replacing lamps, be careful; there are separate lamps for the low and high beams, so they can be easily confused. It is better not to install lamps in high-power headlights; the reflectors may melt and the desired effect will not be achieved. Most low beam headlight problems that cannot be corrected by conventional means can be related to the light control module (LCM). The low beam relay is only available in cars equipped with a light sensor, it is located in the place of relay K1; on most cars this relay is not in the mounting block; the low beam circuit goes through the MUS block. It happens that the tracks in the block burn out; if there are problems, it is better to replace it with a new one. If the windshield wipers turn on spontaneously when the low beam is not working correctly, the problem is most likely in the windshield wiper control unit, located in the center of the dashboard, the topmost block, next to the radio, is best reached from the glove compartment, or by hand through the removed console covers at the feet.

F8 (10 A) - alarm signal . If the alarm does not work, also check relay K9.

F9 (25 A) - stove fan.

If your stove does not work in any mode, the problem may be with the stove speed controller or with the engine. Check the stove motor by applying 12 V voltage directly to it. If it does not work, remove it, open the cover and check the condition of the brushes. If the stove does not work only in the first modes, but works in the last mode, most likely you need to replace the heater resistance, located under the hood on the fan scroll.

The price of these resistors is about 200 rubles. Also check that the filter and all pipes are clean and that air flows normally into the stove. If the stove fan squeaks or turns with difficulty, try lubricating it. If the stove turns on and off, check the connectors and contacts in them, they could have melted or oxidized, in this case, replace the connector.

Cigarette lighter

The domestic auto industry is in no hurry to replace the cigarette lighter with sockets, so all our cars are equipped with its classic version. Lada Priora is no exception. Here it is located in a place of honor - the central floor tunnel, next to the parking brake handle.

This arrangement of the device was not chosen by chance. It is always in sight, you can reach it with your right hand without bending, it does not interfere, and it is impossible for your pant leg to get caught on it. For greater convenience, it is also equipped with a backlight, which makes it easier to find in the dark.

It is worth noting that the Priora’s cigarette lighter differs from previous models not only in location, but also in configuration: its socket is somewhat smaller than that of other VAZs.

Design and operating principle

The Priora's cigarette lighter is no different from the cigarette lighters of other cars. Structurally, it consists of a socket (a hollow metal cylinder) and a metal cartridge with a nichrome spiral inside.

The cartridge is equipped with a plastic button, when pressed, the “plus” is connected to ground through the spiral. The principle of heating the coil here is exactly the same as in an electric stove or iron, but unlike the latter, the Priora cigarette lighter does not have a thermal relay. Its task is performed by bimetallic “ears” inside the cartridge, which, when heated, expand, and the spring ejects the cartridge, setting it to its initial position.

Malfunctions

Like any other electromechanical device, the Priora cigarette lighter tends to break. Sometimes this can be caused by design defects, sometimes by malfunctions in the machine's on-board circuit, and sometimes by the fault of the user himself. Common cigarette lighter malfunctions include:

• sinking of those same bimetallic “ears”;
• burnout of the spiral;
• broken contact in the connector;
• fuse blown.

Malfunctions can also include the burnout of a backlight lamp, however, this is more related to a decrease in the level of comfort than to serious breakdowns. In addition, it does not in any way affect the operation of the device itself and can be easily eliminated by replacing the lamp.

The sinking of the lugs is characterized by the lack of fixation of the cartridge in the pressed position. It can be caused either by the low quality of the metal from which they are made, i.e. defect, or high intensity or long period of use of the cigarette lighter.

The problem is solved by bending the “ears” inward using a thin screwdriver, naturally after de-energizing the on-board circuit. If after a short period of use the problem occurs again, it is better to replace the cigarette lighter.

When the spiral burns out, the cartridge is fixed when pressed, but does not heat up. The fault is diagnosed by ringing it using a car tester. It is not recommended to restore the spiral, as this may lead to a decrease in its resistance, which will make unwanted adjustments to the operation of the on-board circuit. In this case, the cigarette lighter also needs to be replaced.

Contact failure can be easily determined by removing the tunnel lining and checking the condition of the connector. This malfunction is not critical and can be fixed independently in a few minutes.

But as for the fuse, it makes sense to consider this malfunction separately, since its malfunction is most often caused by the human factor.

Replacing the cigarette lighter and its backlight

The cigarette lighter itself is not difficult to replace, you just need to pry the antenna inside the cigarette lighter with a screwdriver and pull out the inner part, and then we take out the plastic itself with the lamp, prying it with a thin screwdriver on both sides and pressing on the antenna. In principle, if you have already purchased a new cigarette lighter, you can simply look at how it works and everything will become clear.

Additional block

Additional relays are mounted on a bar and located under the dashboard, near the front passenger's feet. To get to them, you need to remove the right tunnel lining. Next to the additional relays is the electronic engine control unit (ECU).

If its connector interferes with access to the relay, disconnect it by first removing the negative terminal from the battery.

Circuit breakers

F1 (15 A) – main relay circuit, starter interlock.

F2 (7.5 A) – power circuit of the electronic control unit (ECU).

F3 (15 A) – electric fuel pump . If the fuel pump has stopped pumping (this can be determined by the absence of a sound when the ignition is turned on), check together with relay K2. There may also be problems with the immobilizer, it blocks the pump, see information about F20. If the wiring, this fuse and the relay are good, most likely the fuel pump itself has failed. To remove it, you need to disconnect the battery, remove the rear seat cushion, unscrew the cover, ring and fuel hoses, then carefully remove the entire fuel pump.

K1 – main relay.

K2 – electric fuel pump relay . See above about F3.

Block in the engine compartment

The power fuse box is located in the engine compartment under the hood, near the left strut support. To get to it, you need to open the lid by prying the latch.

1 (30 A) - engine control system circuit . If there are problems with the electronic control unit, short circuits or other malfunctions, this fuse may blow out.

2 (30 A) - vehicle on-board circuit . 3 (40 A) - vehicle on-board circuit .

4 (60 A) - generator circuit.

5 (50 A) - electric power steering circuit.

6 (60 A) - generator circuit.

In case of any problems, it is important not to panic, to think soberly and logically. The most important thing is to diagnose and establish the cause of the breakdown. If you don’t have enough experience or nerves, it’s easier to sign up at the nearest car service center if it has a competent electrician.

I hope this article will help you deal with electrical problems and quickly fix any Priora malfunctions. If you have any experience or information, please leave a comment below, useful information will be added to the article.

Greetings. We will replace the cigarette lighter for the Lada Priora.

We will replace the cigarette lighter assembly and also replace the backlight bulb. To replace it, the floor tunnel is usually removed, we will show you how to do without it.

Tools:

• small flathead screwdriver

How does the fuse work for the Priora cigarette lighter?

The cigarette lighter fuses are made in the form of fusible elements. They are designed to open the electrical circuit in case of excess power or short circuit, and protect other machine systems.

Structurally, such a fuse is made in the form of a plastic case with a special thread or plate that conducts electric current. The body itself is a system for fastening a fusible plate (thread) to the contacts of a block connected to the main electrical circuit of the Priora. In addition, Priora fuses are usually installed in a protective housing.

Step by step replacement

1. Take out the cigarette lighter cylinder.

2. Using a flat-head screwdriver, pry up and remove the metal core of the cigarette lighter. It is best to do this from the inside so as not to damage the plastic.

If it doesn't come out, there may be clips on the inside of the core. They are most often metal. The photo below shows the location of the metal clips. Using a flathead screwdriver, you can bend them and remove the core.

If you are changing the cigarette lighter assembly, I think there is no risk of damaging something on it.

3. Remove the plastic bezel that is illuminated. This can be done using a flat-head screwdriver.

If your bezel backlight works and the bezel itself is not damaged, then you do not need to change it. Simply disconnect the non-working cigarette lighter core, connect a new one and put everything back together.

Power to the cigarette lighter comes through the terminal block. This means it is not difficult to replace it.

4. The backlight bulb is assembled with a plastic rim. To replace the light bulb, remove the small plastic cover.

Next, insert a flat-head screwdriver as shown below and pull the edge toward you. There is a small groove on the body and the light bulb is held in place by it. I think everything will be clear from the photo below, but if you have any difficulties, watch the video tutorial.

5. Remove the lamp from the socket and install a new one. The light bulb simply pulls out towards itself.

6. Install the socket with the new lamp into the rim. Be sure to align the grooves so that the cartridge snaps into place.

7. Install the small plastic cover.

8. Put the rim in place. There is a groove in the floor tunnel and a corresponding groove on the rim body. When installed, they must match and the light bulb must face backwards.

9. Change the cigarette lighter core and install it with the metal contact back until it clicks.

When installing, the contact should be backwards, just like the light bulb. Power is supplied to the backlight through this contact.

10. Install the cigarette lighter cylinder.

After reassembly, we connect the battery terminals and check the operation.
