Algorithm for replacing and repairing trapezium wipers on a VAZ-2110

A hot topic for owners of the corresponding model is replacing the windshield wiper trapezoid on a VAZ 2110. Experienced motorists know: this part is subject to rapid wear

, or rather not the part itself, but some of its components. In particular, the bushings are made of plastic. Whether the design is to blame for this, or some other defects, they wear out much faster than other mechanisms.

Meanwhile, the performance of windshield wipers is a guarantee of safety in bad weather.

Replacing the windshield wiper trapezoid on a VAZ 2110 is a necessary measure that has to be taken to maintain the wipers in working condition. At the initial stage, this problem manifests itself in a weakening of pressure - in other words, the windshield wipers cannot cope with flows of water or heavy snowfall. Returning to the original position is difficult; you can actually feel the strain with which the wipers move across the glass.

The presence of such symptoms indicates wear and tear on the trapezoid mechanisms.

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.

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.

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.

Alternative solutions

Often this happens because they do not see alternatives and are not familiar with them.

For all VAZ 2110 models, regardless of the year of manufacture, it is possible to install windshield wipers for the driver and passenger sides of the same size - 20 inches. The length of the brush is 508 millimeters.

But this size can be increased to 530 millimeters. It is not recommended to install more, since this way the windshield wiper will not be able to work effectively, and the drive simply will not cope with the load. As a result, too long brushes cause squeaking and jerky work. Plus, don’t count on a long service life of the wiper mechanisms.

The original windshield wipers for the 10 are quite good. But there are more expensive, but also more highly efficient, high-quality devices.

But as practice shows, on the windshield of the VAZ 2110, as well as other VAZ models, they do not look very nice, because the fasteners on the leash turn out to be massive. Although if you modify them a little, you will get a very good result.

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.

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:

1. 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;
2. 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:

1. 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;
2. 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;
3. 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;
4. 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.

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:

1. First you need to disconnect the negative terminal on the battery.
2. Then you need to tilt the mount towards you and remove the brush.
3. If there is a decorative trim, it must be removed.
4. By unscrewing the bolt, you can remove the old brush.
5. 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.
6. 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.

Electrical breakdowns are as follows:

1. The electric motor does not work completely . After turning on the wipers, you can’t hear them working and the wipers themselves remain motionless. The cause of this breakdown will most likely be stuck motor brushes - then they need to be returned to the correct position. Less often, the armature burns out - in this case, you will have to completely replace both the electric motor and the gearbox (they are sold only as a set).

1. You can't hear the electric motor running . The wipers also don't move. After they are turned on, only the click of the bimetallic fuse is heard. The reason for this in winter is almost always freezing of the electric motor brushes. Often after this, when persistently trying to turn on the wipers, the bimetallic fuse or, less often, the electric motor armature itself blows. This problem can be easily solved by simply thawing the brushes and removing moisture from them. In more serious cases, you need to replace it with a new fuse or the electric motor itself.

1. The wipers work, but in intermittent mode they continue to run continuously . At the same time, there are no sounds of alternating rotation of the electric motor armature. This problem is usually solved by simply replacing the control relay. But before doing this, you just need to check and re-clean the contacts of the limit switch - they sometimes oxidize or burn.

1. The work of the wipers is carried out slowly and with stops in unpredictable places of the working stroke. The windshield wipers do not occupy the lower position at all. In this case, the cause is most often the limit switch - you need to adjust it by bending the contacts. If incorrect operation continues, the electric motor will have to be completely replaced.

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.

Methods for attaching brushes

Before 1999, most car manufacturers used a type of mounting for OEM windshield wiper blades called a "hook" or "hook". This is a universal device in the shape of the letter “U”, which allows you to snap the brush into place and not worry about the reliability of its installation. The following types of mounts are currently gaining popularity:

1. Side pin - appeared in 2005 on BWM, Volvo and other cars. Allows brushes to be fixed using a special 22 or 17 mm side pin.
2. Button or “Push Button” is an adapter for standard 16 mm wide wiper blades. It is enough to snap the device into place for fastening, and to remove it you need to press a special button.
3. Pin lock - fixation of brushes using a special built-in lock. Used in Audi cars.

“Push Button” mounting scheme

This is not a complete list of types of fastenings. Each manufacturer can use their own designs for fixing brushes.

Despite the relative simplicity of windshield wipers, it is difficult to imagine a modern car without them. Drivers can control the operation of the wipers directly from the cabin, remove dirt and improve visibility of the road situation. And electronic systems automatically monitor the cleanliness of the glass, increasing the comfort and safety of driving without human intervention.

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.

Modify the windshield wiper relay

You should start with why this is even needed. In heavy rain, the wipers of the VAZ 2101 - 2107 do an excellent job, providing a fairly decent driving speed. But, if the rain drizzles disgustingly, hundreds of thousands of “classic” drivers curse the factory for the fact that it is impossible to select the required frequency of operation of the wipers.

As a result, it turns out that windshield wipers rub on dry glass for quite a long time, and there is nothing good about it. To neutralize this unpleasant phenomenon, you have to turn the wipers off and on manually.

There will also be those who will say that there are no difficulties in this - turn it off and on, yes, you can agree, but as soon as you drive at least a hundred kilometers, your opinion will change.

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.

1. 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.
2. 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.

Brush sizes

Standard sizes of windshield wipers for Grant:

• according to the technical manual, the size of the driver's wiper is 600 mm;
• The size of the passenger cleaner is 410 mm.

Alternatively, you can use longer windshield wipers:

1. On the passenger side, you can install a longer wiper, its size should be no more than 450 mm, this will allow it to engage a larger amount of surface.
2. As for the driver's brush, it is better not to experiment here. For example, if you install a 610 mm wiper, this will cause it to touch the car body during operation, and accordingly, a knock will appear (video author - TheLadaKalina 2).
