Wiper design
The main parts of the windshield wiper are the supporting frame and the cleaning element.
Wipers with metal frame
The supporting frame is made of metal or plastic. Wipers with a metal frame are more durable and strong. This frame is used to make winter windshield wiper blades.
Wipers with plastic frame
There is another type of brush design - frameless brushes. The frame in such brushes is a cleaning rubber band and the wiper itself is made entirely of rubber.
Frameless wipers
The cleaning element is made of soft rubber or silicone, which ensures a tight fit to the windshield and excellent cleansing of moisture.
Types of wipers
- Classic.
The design consists of seven metal “rocker arms” arranged pyramidally. The largest arc holds two smaller ones, which, in turn, hold even smaller ones and are attached to a rubber blade. This design allows the downforce of the wiper to be evenly distributed. Slowly going out of fashion, these wipers are falling in price every day, while performing their functionality very well in the warm season. The main enemy of such a wiper is snow. But it is impossible to say that these brushes are worse in functionality than frameless ones. The pressing effect of such a design loses its properties over time. Therefore, it is better to change the brush frame itself after a few years.
- Frameless.
The “rocker arm” system for this type of wiper is replaced by a thin metal plate that passes through the entire length of the brush. It is a frame, despite the so-called frameless classification. They tolerate snow better, but this design has a disadvantage - the distribution of downforce here is worse than that of “rocker arms”. In the cold there is a shrinking effect. The advantages of these brushes over the previous ones can be called design. Although the taste and color as they say... .
- Winter brushes.
They repeat the classic summer design, but all its moving parts are hidden under a rubber cover. But these brushes are not very suitable for summer, since the casing causes too much windage. If the speed is above 90 km. at an hour, the brushes begin to move away from the glass. As good as such brushes are in winter precipitation, they are just as bad in summer precipitation.
- Hybrid.
These brushes are the latest development for today. Metal “rocker arms” here replace three plastic arcs, they also act as a winter cover, thereby allowing these wipers to be called hybrid. Another distinctive feature of these wipers is improved aerodynamics. Headwind increases downforce. Although in such a design there is something to freeze on.
In conclusion, we can say that in winter it is better to use winter wipers, and for summer any wipers except winter ones are suitable. It's up to you to choose. In any case, new wipers, no matter what design, are better than those that do not perform their functions at all.
What is a windshield wiper trapezoid and what is it for?
The trapezoids are around here somewhere!
The wiper trapezium is a special unit that converts the engine impulse into forward movements of the windshield wipers.
Simply put, it is she who is responsible for their movement along the windshield or rear window of the car. Since weather conditions are often unpredictable, and the windshield must provide complete visibility, failure of this part must be quickly identified and repaired.
Principle of operation
Most often, plastic bushings wear out in trapezoids.
This is interesting: What happens if you pour oil into the engine?
Although, at first glance, it seems that the movement of the brushes occurs directly, in fact, a trapezoid, which is an electromechanical unit, is responsible for it. It works on the following principle:
- The windshield wiper motor uses the finger, which drives the trapezoid itself.
- Due to the connection of the gearbox and shafts, oscillatory movements occur, causing the brushes to move along the glass, cleaning it.
It often happens that the trapezoid fails. This happens especially often after or during the winter season. Some inexperienced VAZ-2110 owners turn on the “brushes” without bothering to clear the snow from the glass. Often the wipers freeze to the glass, and an attempt to move them ends in breakage. To prevent this from happening, you should always check the brushes before turning them on in winter for freezing.
How to determine that a trapezoid is “kirdyk”
Kirdyk is a slang word meaning an extremely bad situation.
It happens that the retaining ring of the bushing breaks and the rod simply flies out.
The slightest disturbance in the operation of the trapezoid can lead to incorrect operation of the wipers. Usually this part is replaced with a new one, although in some cases you can get by with installing a repair kit. Its cost is significantly lower than the price of the entire part, although repairs will take much more time. Here is a list of the main signs by which you can determine that a part will soon fail:
- Windshield wipers begin to do their immediate job poorly. This occurs due to the weakening of pressure.
- An unusual noise is heard during operation.
- A backlash appears, which can be determined even visually, since the glass will be difficult to clean.
- It happens that the brushes move in one direction easily, but back with difficulty, constantly slowing down.
What affects the condition of the trapezius
The main cause of all problems associated with the trapezoid is the location of the mechanism. The wiper motor and trapezoid are located directly under the glass.
Dirt, small abrasive particles, water and washer fluid constantly accumulate in this area.
This leads to wear at the moving joints and loss of lubricant. Active wear of the plastic bushings of the hinges is observed, backlashes appear, resistance noticeably increases during operation and the load on the motor increases. In such conditions, the trapezoid for the wipers and the motor quickly fail.
As a rule, the VAZ 2110 trapezoid requires revision every 2 years. Such an inspection should mean cleaning the trapezoid from dirt and additional lubrication. If this is not done, after 5-6 years the trapezoid will need to be replaced or repaired (a trapezoid repair kit is used).
The wiper motor and trapezoid are located directly under the glass, so some of the water or washer fluid falls on them. In addition to water, dust, dirt and various small debris get there. All this leads to a change in the properties of the lubricant and deterioration in the performance of the trapezoid. When the lubricant loses its properties, the plastic bushings of the hinges begin to wear out, resulting in backlash and increasing resistance during operation.
Trapezium wipers - replacement for VAZ 2110
The trapezium of the wipers transmits the force from the engine to the windshield wiper arms. The best quality of windshield cleaning will be only if all elements of the wipers are in working order. If the trapezoid hinges are clogged with dirt or the lubricant has dried out, the motor energy will not be enough for proper cleaning. Therefore, owners of cars of the tenth family are forced to repair the trapezoid once every 5–10 years in order to avoid deterioration in the performance of the wipers.
Spare part selection
The catalog number of the original wiper trapezoid is 2110-5205010. Give preference to trapezoids from manufacturers:
- Balaton;
- At program;
- Startvolt.
Part of the old and new sample
Selecting a new part for a VAZ-2110 is not such a simple matter. Not everyone knows that there are old and new trapezoids.
The old-style trapezoid rods are secured with two studs.
The new type of rods are installed without problems if you remove one pin.
Therefore, it is better to remove the old part and take it to an auto parts store. They are not only attached differently, but also differ in the connectors through which they are connected to the motor. If you can’t find an old-style trapezoid, and this is exactly what you have, you’ll have to redo the system or look for a used part.
- As a rule, trapezoids of a new type are available for sale from various manufacturers. One of the popular models has the article number VLT2110–5205010-Р.
If the windshield wiper motor is working properly, you can only change the trapezoid itself.

Do-it-yourself modification and replacement of wipers
Which wipers are better is up to the car owner to decide. Those installed on the VAZ 2110, as well as on the UAZ, do their job well from the factory, but it can be modified with washers from other companies that are of higher quality. Many people are attracted to frameless brushes - this is a good option. They are compact in size and equipped with a special leash mechanism. True, they do not look very attractive on the VAZ 2110, since the fastener to the standard washer arm turns out to be massive. Therefore they need improvement.
Frameless car washers
To perform a replacement or modification, you must perform the following steps:
- First you need to disconnect the negative terminal on the battery.
- Then you need to tilt the mount towards you and remove the brush.
- If there is a decorative trim, it must be removed.
- By unscrewing the bolt, you can remove the old brush.
- Before replacing parts, be sure to check the dimensions of the new washer with the old one. It is advisable that the new one does not exceed the size of the old one by more than 2 cm.
- Installation of the new kit is carried out in the reverse order.

After upgrading, you should check the functionality of the unit: whether the brushes creak, how they work when switching modes. At high speeds of the windshield wiper motor, the wipers should work quickly, at low speeds - slowly. In addition, they must support intermittent operation.
Sorry, there are no surveys available at this time.
Replacing the trapezoid
The replacement process is simple, but it involves manipulations that require increased attention and accuracy - there is a danger of damage to neighboring components and mechanisms.
We de-energize the car by removing the “negative” terminal. We remove the special wind cover (the so-called “jabot”) and the expansion tank. The latter must be removed at an angle - there is a possibility that some of the coolant will spill out, so it is useful to first drain some of it into a previously prepared container.
Then you need to turn off the gearmotor
. To do this, remove the corresponding connector. Carefully pull out the trapezoid (depending on the year of manufacture, it can be attached to two or four studs) and carefully remove it from the air supply box. That's it, the work is completed.
Installation of a new trapezoid is carried out in the reverse order.
How to remove the windshield wiper trapezoid
To remove the trapezoid you will need:
- key to 10;
- thin flat screwdriver;
- crosshead screwdriver.
First of all, you need to remove the wipers. To do this, you need to remove the plastic pads and unscrew the nuts with which they are attached to the trapezoid studs. Then unscrew the screws and side fastenings of the protective casing (jabot) and remove it. If the fasteners do not come out, treat with WD-40. Before removing the casing, make sure to remove all screws, bolts and nuts. If the cover does not come off, look for a fastener that you did not remove. Lifting the frill, disconnect the washer fluid supply tube from the tee, and then move the casing to the side.
Remove the belt that supports the radiator tank and move the tank to the side. Then pull out the partition (sound insulation), which is located behind the tank. Don't forget to remove the washer fluid supply tube from it. Disconnect the electric motor power connectors. After this, unscrew the bolts securing the trapezoid and electric motor. To remove the trapezoid, you must either struggle for a long time, coming up with various options, or place a thin flat-head screwdriver under the far end (relative to the motor) of the lower rod of the trapezoid and pull out the entire structure as if on a slide. You can also turn the left edge of the trapezoid clockwise and pull it out, then remove the engine.
Putting the trapeze in place
Usually, installing the trapezoid into place does not cause difficulties. Insert it and secure with bolts. Do not overtighten the motor mounting bolt; the motor may need to be turned slightly to get the trapezoid to operate smoothly. After making sure that the trapezoid is working properly, tighten the electric motor mounting bolt, install and secure the sound insulation, frill (do not forget to connect the washer tube), and the expansion tank. Insert the plastic plugs and install them in place, install the arms with brushes and check the operation of the wipers in all modes.
Step-by-step replacement process
- Using a slotted screwdriver, remove the rubber caps and unscrew the two nuts securing the wiper arms. Ten head nuts.
- Remove the wiper arms by pulling them towards you by hand.
- Using a slotted screwdriver, remove the four plastic plugs and remove the four Phillips screws. Screws secure the frill trim under the windshield.
Using a Phillips screwdriver, unscrew the seven screws securing the engine shield insulation to the frill trim. The fastening screws are located along the entire length of the insulation.In the corners on the right and left, unscrew the frill under one nut. Ten head nuts.
Lift the cover up and move it to the side.
Lift the coolant expansion tank up and to the side. There is no need to remove the hoses leading to the tank.
Unscrew the two nuts securing the trapezoid to the crossbar under the windshield.
In the depths, unscrew the last bolt securing the trapezoid and remove it along with the motor. Ten head bolt.
If necessary, unscrew the three bolts securing the motor and move it to a new trapezoid.

Trapezoid repair
During repairs, it is necessary to clean all elements of the trapezoid from dirt and inspect the studs. If wear is detected on their ribs, the trapezoid will have to be replaced. Repairing a trapezoid involves replacing the plastic caps. To do this you will need a repair kit and boiling water. First, disassemble the trapezoid using a pry bar or a heavy-duty flathead screwdriver as leverage. After this, cut off the old plastic caps. If you can’t cut it, use side cutters and bite off the caps piece by piece until you can pull them out of the trapezoid rods. You can also hold the ends of the trapezoid in boiling water, 2 to 3 minutes is enough, then push the caps out of their seats.

Three types of trapezoids were installed on cars of the “tenth” family - VAZ 2110, 2111 and 2112, which differed in minor details. Therefore, there is a possibility that either the trapezoid rods or the caps will have to be adjusted. Remove the cap and inspect it. If there is a fixing protrusion on top of it, check the recess for it on the rod seat. If there is no notch, you will have to either cut off the protrusion on the cap (does not affect the performance and reliability of the trapezoid) or saw through it in the draft. If there is no protrusion on the cap, no adjustment will be necessary.
Clean the rod and seat, then lower the cap into boiling water for 10 - 15 seconds. After this, it will soften and easily fall into place. Do not install a cold cap as this will destroy it. After the cap has cooled completely (20 minutes), the rod is ready for assembly. Before assembly, lubricate the bushings with graphite grease.
Check the serviceability of the electric motor. To do this, disconnect it from the trapezoid (you need to unscrew the fastening nut) and connect it to the car battery. When working, it should make a low buzzing sound. If you don't know how to connect the motor to the battery, then connect it to the power connector. Turn on various operating modes of the electric motor for 10 - 15 minutes. After that, feel it. If the motor gets hot, it needs to be replaced. An electrical technician can try to repair this device, but regular drivers and car enthusiasts need to replace it.
Repairing a trapezoid using a repair kit
If the bushing in an old part is simply worn out, it is not necessary to change the entire trapezoid. It is enough to simply repair it using a repair kit. As a rule, it has everything you need. To repair the trapezoid, you will also have to remove it. When removing the wiper arms, you must try to act extremely carefully, otherwise you may damage the glass or paint on the edge of the hood.

Recommendations
Often the wipers on the VAZ 2110 begin to work poorly as a result of problems with the electric motor, and not the trapezoid. For this reason, when servicing or replacing the trapezoid, it is important to check the serviceability of the electric wiper motor.
- To check the wiper motor, you need to disconnect it from the trapezoid by unscrewing the mounting nut. The motor is then connected directly to the battery or via a standard power connector. A low buzzing sound during operation is considered normal. At the same time, noise, grinding and crackling when power is supplied are unacceptable. We also recommend reading the article on how to replace windshield wiper blades. From this article you will learn about the features of replacing wiper rubber bands, as well as what you need to consider when performing this procedure.
- Experts also recommend turning on different operating modes so that the engine as a whole runs for about 10 minutes. Next, you should feel the motor. Strong heating will indicate that the wiper motor will soon fail and needs to be replaced. It is also possible to repair the motor, but it is easier and faster to purchase a new device, since its cost is not high.
Finally, we note that the VAZ 2110 windshield wiper requires regular trapezoidal maintenance. At a minimum, cleaning from dirt and lubrication is necessary. This allows you to significantly increase the service life of the mechanism and reduce the load on the electric motor, increasing its service life and productivity.
Main malfunctions of the mechanism and ways to eliminate them
When is windshield wiper motor repair required?
Before removing, checking the motor and replacing it, familiarize yourself with the main faults of the unit:
- The device does not function, the safety element does not work either, but its integrity does not work. In this case, you must first diagnose the integrity of the wiring and contact connections, and if damage is detected during the diagnosis, they must be eliminated. If everything is fine with the wiring, then you need to check the steering column brush switch; it is quite possible that it has failed. Naturally, the problem may also lie in the electric motor, for example, its contacts are burnt or the brushes are acidified; if this is the case, then it will need to be repaired or replaced. It would not be superfluous to diagnose the wiring that goes to it and the block. It is recommended to clean the safety element or replace it if cleaning does not produce results. If after performing all these steps the system still does not work, then you will need to diagnose the integrity of the winding of the so-called motor armature. If the diagnostics show that the circuit is missing, then either the armature or the entire electric motor assembly is replaced.
- The brushes do not work, while the safety element is working, and the fuse in the power circuit regularly fails. In this case, the levers are diagnosed - perhaps they cannot work as a result of deformation or freezing of the brushes to the windshield. It is much worse if the failure of the unit is caused by a short circuit in the armature circuit, then you will have to decide what to change specifically - the armature or the gear unit.
- The device does not operate in intermittent mode. As a rule, such a malfunction is caused by a failure of a relay or switch. In both cases, it is better to replace the failed mechanism.
- The wipers operate intermittently but do not stop. In this case, the problem, as a rule, lies in the inoperability of the relay or limit switch. If the reason is the switch, then most likely the spring plastic is not pressed to the end by the gear, and in this case it will just need to be bent (the author of the video is Igor Ivanov).

If the wipers stop turning on
When the VAZ 2107 windshield wiper stops working in both positions of the mode switch, you should start looking for the fault with the wiper fuse. It is installed in the electrical network to protect it from overloads that occur during malfunctions, short circuits or increased load on the wiper motor. If the fuse is working, you should check its contacts. Often they are highly oxidized and prevent the passage of current. Cleaning the contacts is simple - you need to remove the fuse and clean the contacts with a knife, screwdriver or sandpaper. Usually these actions are enough, but sometimes the reason lies in a malfunction of the relay, switch or motor. But more on that below.
If the wipers do not work intermittently
This problem is associated exclusively with a malfunction of the VAZ 2107 wiper relay. The cyclic operation of the wipers is ensured by closing/opening the relay contacts and, accordingly, the power supply circuit of the wiper motor.
The test should begin by monitoring the power supply to the relay block. This is done like this:
- remove the relay;
- turn the wiper switch to the intermittent position;
- Use a control indicator to check the presence of voltage at the terminal.
If there is no voltage, it is necessary to replace the switch or repair the open circuit. If voltage is supplied but the relay does not work, the latter must be replaced. The design of the relay does not provide for the possibility of repair.
If the wipers do not stop at the lowest point
Sometimes when you turn off the wipers, the brushes stop not at the lowest point of the trajectory, but in another arbitrary place.
The problem lies not in the VAZ 2107 wiper relay, but in the drive gearbox. It contains a limit switch actuated by a cam. The operation of the cam controls the position of the brushes after turning off the power on the switch lever. Gearbox failure most often occurs in winter, when the driver turns on the wipers that are frozen to the windshield.
To replace the gearbox, you must dismantle it along with the engine and install a new one.

If power is supplied but the engine does not run
There are several reasons why the engine may not work when power is applied. The most common are shearing or wear of brushes or failure of windings. The brushes can wear out over time, or they can freeze to the contacts and break when the VAZ 2107 wiper relay is turned on and power is supplied to the engine. The winding most often burns out when the motor is overloaded. To check, repair and replace the gearbox with the windshield wiper motor, it is necessary to remove the unit from the vehicle.
Let's summarize
Replacing a trapezoid without experience in car maintenance will take approximately thirty minutes. The price for replacing a VAZ 2110, 2111, 2112 trapezoid at service stations is from 500 to 1000 rubles.
