Replacement and repair of trapezium wipers VAZ 2110, 2111, 2112

Replacing the windshield wiper motor and trapezoid

The design of the windshield wiper on the VAZ 2110 is quite reliable and during normal operation the motor and the trapezoid itself can easily move all 300,000 km, which has been proven by the personal experience of many owners. But there are also exceptions to the rules.

It often happens that the splines are bypassed or the trapezoid structure simply breaks down. If you have such problems, the repair procedure will be discussed below.

To replace all the wiper parts, we will need the following tool:

• screwdriver flat and Phillips

10 mm socket head

• ratchet handle

To do this job, you first need to do some preparatory steps, namely:

1. Remove the windshield trim (jabot)
2. Remove the insulation and seal under the hood
3. Disconnect one end of the expansion tank rubber and move it to the side

Review

Many dozens of car owners agree that the windshield wiper motor of the VAZ 2110 is quite frail - both in old and new modifications. Moreover, its operation depends on many parameters: the condition of the wiper rubber bands, wind, the amount of water pouring onto the glass, the voltage supplied to the wiper motor. Usually there are more complaints about the front window wiper, but the rear window on models 2111 and 2112 also has exactly the same gear motor.

When all the preparatory steps are done, everything will look something like this. The arrows at the top show the attachment points of the two nuts:

You need to unscrew them, of course.

After this, we disconnect the clamp securing the expansion tank and, lifting it up a little, move it to the side to gain access to the third trapezoid mounting nut.

After this, the nut can be unscrewed; it is located at the very bottom:

After you have dealt with this, you can carefully turn the trapezoid and remove it from the left side, slightly bending the metal frame below the windshield to the side (the force required is very small - there is no point in talking about any real bending!)

And lift it almost all the way to take it out:

All that remains is to disconnect the power plug:

And now you can finally remove the entire structure of the trapezoid and the wiper motor from the bore. If you need to disconnect and replace one motor, then in principle there will be no difficulties with this - just unscrew it and replace it.

Installation of all removed parts occurs in the reverse order. It is worth mentioning the prices of these spare parts. The cost of a trapezoid assembly with an engine for a VAZ 2110 is about 2000-3000 rubles from the manufacturer AvtoVAZ. Chinese analogues cost about 2000 rubles.

Rear window wiper

The rear electric motor can also be removed and a new one installed. To do this you need:

1. Remove the holder and rear wiper blade;
2. Remove the rear door from the upholstery;
3. Remove the battery negative terminal wire;
4. Disconnect the terminal block from the windshield wiper motor wiring;
5. Loosen the nuts securing it to the door (there are 3 of them) and dismantle the motor;
6. Install a new electric motor. Replacement is in reverse order.

Rear wiper motor gearbox for VAZ 2112

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 corrected.

Principle of operation

Most often, plastic bushings wear out in trapezoids.

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:

1. The windshield wiper motor uses the finger, which drives the trapezoid itself.
2. 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 .

Device design

The design of the windshield washer on the VAZ 2101 consists of a gearmotor powered by an incoming current that drives the washers, a switch, a switch, a relay for switching on the intermittent mode, an additional relay, etc.

Glass cleaner device

The node consists of:

1. Windshield wiper trapezoids: with its help, the motor transmits movement. It wears out quickly, so sometimes repairs to the trapezoid are necessary.
2. An electric motor drives the wipers of the VAZ 2110. If the motor burns out, the entire unit will fail.
3. The windshield wiper pump pumps cleaning fluid. If the electric pump breaks down, then, despite the operation of the wipers, the windshield will not be cleaned.
4. The purpose of the tank is obvious - window cleaning liquid is poured into it.

Thanks to the electric motor, the wipers on the VAZ 2110 can operate in three modes:

1. Intermittent. The switch lever is in positions II and III.
2. Constant - with a low speed of movement of the brushes. The switch lever is in position IV.
3. Constant - with fast movement of the wipers. In this case, the shift lever is in position V.

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:

1. Windshield wipers begin to do their immediate job poorly. This occurs due to the weakening of pressure.
2. An unusual noise is heard during operation.
3. A backlash appears, which can be determined even visually, since the glass will be difficult to clean.
4. It happens that the brushes move in one direction easily, but back with difficulty, constantly slowing down.

All these problems lead to the fact that the windshield remains dirty, with streaks and smudges.

Repair kit for VAZ-2110

Most often, plastic parts are destroyed in the trapezoid. In this case, a repair kit can help.

When purchasing a repair kit, pay attention to the part number.

If metal parts are damaged, you will have to replace the entire trapezoid. As a rule, the trapezoid is destroyed as a result of an accident, or due to careless handling of the windshield wiper system.

Causes of malfunction

Therefore, if the brushes are completely frozen, or only squeak, the root cause should be sought in the electric motor. Not forgetting that in addition to electrical problems, there may be mechanical problems.

The most common ones are:

• When you turn on the windshield wiper, you can hear the motor running, but it only jerks or remains motionless. First of all, you need to suspect that the nut securing the crank to the gearbox axle has become unscrewed or loosened;
• If the windshield wipers operate but are not synchronized, the leash may be the culprit. Most likely, the nut securing it has become loose. Before tightening it, you need to put the wipers in the correct position.

If the electrical part is faulty, the symptoms will be:

• The wipers work slowly, stop wherever they want, and do not want to take the lower position. The limit switch may be to blame for this. Its adjustment consists of bending the contacts. If such repairs do not help, then the entire electric motor assembly needs to be replaced, since it is sold only together with the gearbox;
• Intermittent mode is turned on, but the brushes work without stopping. Most likely the relay has failed and needs to be replaced. This is definitely a relay if on a VAZ, when the intermittent mode is on, the noise of the rotating armature of the wiper motor is inaudible. But if the replacement did not help, the contacts of the limit switch may have oxidized or burnt;
• You turn on any of the modes, and you only hear the thermometallic fuse click. The brushes “stand still” and the anchor is also inaudible. First of all, check to see if the brushes are frozen and therefore do not move. By the way, fuse F5 often blows in this case. Another possible reason is that the anchor burned out;
• The electric motor does not work, although both fuses are intact. It is necessary to check all the contacts that the drive has, as well as the motor. Perhaps the brushes are stuck or the armature is burnt out.

Having skillful hands and basic knowledge of how the wiper mechanism works, there is no need to contact a paid service to make repairs or change windshield wipers. Replacing the windshield wiper motor on a VAZ 2110 is also quite simple.

Parsing is carried out in this way:

• Remove the dashboard;
• On the left we find a relay screwed to the body. If the relay turns out to be faulty, then repair is unlikely to help it; a replacement is needed;
• We check the fuse responsible for the wiper drive;
• We disassemble the steering column to inspect the switch. If it turns out that the switch has insulation damage or other problems, it means it needs to be replaced;

• We unscrew the motor from the body and check for functionality. If there is a minor problem, it can be repaired, or perhaps it will need to be replaced, along with the relay. There is no point in repairing the relay separately - its cost is cheap;
• Inspect the drive; one of the possible faults is that its pulley has broken.

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.

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.

Replacement procedure

So, you have chosen a gear motor for your VAZ - one of the first three. Let's look at how it is replaced. When performing this work, there is no need to disassemble the entire windshield wiper system. We proceed like this:

1. Disconnect the negative terminal from the battery;
2. Having noted the position of the brushes on the windshield, unscrew and remove the levers;
3. Remove the cover from the fairing;
4. Unscrew the nut securing the crank mechanism bracket to the motor axis;
5. Unscrew and remove the bracket itself. It is secured to the body with 3 bolts;
6. We remove the non-working or poorly functioning motor from the studs;
7. Replacing the old one with a new one is done in the reverse way.

Replacing the trapezium wipers of a VAZ 2110

I don’t think anyone will argue with the fact that good visibility is necessary to drive safely. To do this, it is necessary that the mechanism driving the brushes works, the trapezoid of the wipers is in good working order, but the brushes themselves must be in good condition and appropriate for the time of year.

Bad weather reminds us to regularly replace our windshield wiper blades. Some manufacturers of these extremely important parts recommend changing brushes once a year. The fact is that under the influence of the environment, rubber inserts gradually dry out and lose their elasticity. Hard rubber works like a scraper, leaving streaks and streaks on the glass. Run your finger along the blade of the eraser; if it is worn out and dull, you need to replace the brushes. Don’t skimp on small things and replace dry or worn wipers before the slushy season sets in.

Replenish the washer fluid supply in the washer barrel in a timely manner. To avoid poisoning from toxic pores, buy only proven glass cleaning liquid.

How to care for your wipers to extend their lifespan

To ensure that your wipers last as long as possible, follow these tips:

• Wipe dirt-stained brushes with a clean, damp cloth or sponge. This way you will not only get rid of dirt, but also protect the glass from scratches.
• If the front glass is covered with a layer of dust and the car washer fluid has run out, do not turn on the cleaner. This will also cause scratches on the glass.

• In winter, especially during snowfalls, do not leave the wipers leaning against the windshield - they will freeze. It is better to raise the leashes so that the brushes are suspended.
• If the windshield wipers are still frozen, do not under any circumstances try to tear them off by force. This will only damage the rubber band. Start the engine, turn the heater on to blow the windshield and wait until it defrosts.
• You should also not knock ice off the frame or brush. Gently bend the elastic until it peels off in small pieces.
• When replacing wipers, place some thick cloth on the windshield. This will protect it in case the spring-loaded leash slips out of your hands.

Types of wipers

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.

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... .

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.

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.

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.

What affects the condition of the trapezius

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.

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.

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.

Replacement process

The easiest way to get rid of problems with VAZ-2110 windshield wipers is to contact a service station. There the trapeze will be replaced in an hour or an hour and a half. But if unscrupulous repairmen notice that the owner does not understand the cause of the breakdown at all, they can repair the car for half a day, saying that the problem is very serious.

Therefore, the best option to save money is to replace the part yourself. This process works as follows:

First of all, you will need to dismantle the old trapezoid. To do this, you will have to disassemble and remove the windshield wiper arms. To do this, you will have to unscrew two nuts with a 12mm wrench.

Care must be taken when removing the arms, as the powerful springs create a problem during removal. It is better to bend the leashes first.

After this, the plastic part is removed

To do this, the screws are unscrewed.

The next stage includes removing the plugs and other fasteners.

You can reach the trapezoid only after removing the plastic parts of the casing. The trapezoid is attached to the motor. It will also have to be dismantled.

The trapezoid, together with the motor, is attached to the body using a bracket. You need to disconnect them.

A new spare part must be assembled before installation, since it is in a disassembled state. When connecting parts, you need to make sure that all parts are aligned and adjusted. Only after this are the nuts tightened.

Before installing a new trapezoid, it is advisable to lubricate all its rubbing parts with graphite lubricant. Some advise using lithol, but it loses its properties at sub-zero temperatures.

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.

Plastic bushing repair

If you can’t find a repair kit specifically for your model, don’t despair.

The main thing is to cool the drill frequently, otherwise the plastic may become deformed. If the sleeve does not fit in outer diameter or length, it can be sharpened with a file. The old trapezoid is disassembled, after which it is necessary to install new elements to replace the worn ones.

Before installing the frill, we check the operation of the new trapezoid.

Using a repair kit will reduce costs, but increase labor costs. Therefore, every VAZ-2110 car owner chooses the best option for himself. Replacing a trapezium yourself can be done alone in 2–3 hours, the main thing is not to damage the plastic elements.

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.

Helpful information

Before purchasing a part, you need to find out which trapezoid is needed: there are “old” and “new” samples, indistinguishable in appearance. However, there are quite serious internal differences, which makes it impossible to install the “wrong” trapezoid.

However, our mechanics found an interesting way: a small modification (removing “extra” fastening studs on both sides of the body) solves the problem.

Moreover, experts advise installing a trapeze from Priora on a VAZ 2110 - in this case, a rework is also needed, but some cost savings are achieved (spare parts from Priora are cheaper). The modification consists of replacing the wiper arms ( on the VAZ 2110 they are slightly smaller

In addition, the connectors for connecting the electric motor are different. Here you need at least minimal knowledge in electronics, because you will have to install new wiring, reliably insulating it.
