Repair of trapezium wipers VAZ 2110 - replacement of trapezoid wipers

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:

• flat and Phillips screwdriver;
• 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.

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.

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. When removing the levers, you need to be careful, since powerful springs create a problem when removing them. It is better to bend the leashes first.

Disconnect the wiper motor gear pads.

Unscrew the nut of the left trapezoid fastening.

Unscrew the nut on the other side.

Unscrew the fastening of the gearmotor bracket.

Remove the trapezoid from the studs and remove it.

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.

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.

Wipers do not work on VAZ 2110

If it's snowing or raining outside, wipers become indispensable elements of the car.

Wiper elements for VAZ 2110

In our material we will talk about the mechanism of the VAZ 2110 wipers, discuss the main reasons for their malfunction, the issue of repair and the search for alternative options to standard windshield wipers.

Device design

Wiper circuit

First, let's try to understand how the windshield wiper circuit on the VAZ 2110 works and what components form a solid unit called a windshield wiper.

Where does which wire go, or just a diagram

Connecting wipers and washer

“Plus” power is supplied from the ignition switch through fuse No. 2 at 10 Amp of the mounting block. The permanent “plus” goes along the black and yellow wires to contacts “4” of the connectors of the gear motor and the steering column switch. It should not disappear even when the switch is in the “off” position. The blue wire supplies “+” 12 V power to the motor when the switch is in the “continuous mode” position. On the blue-white wire, in the “off” position there should be a “minus”, and in the “continuous mode on” position the “minus” is turned off. This is done to slow down the motor when the power to the closer is turned off.

The red wire supplies the relay with “+” 12 V from the switch when the intermittent mode is turned on. At the moment of operation, contacts “2” and “4” close, and “1” and “3” open, the motor starts working and the brushes make one or two movements. Then “+” 12 V is turned off, and contacts “1” and “3” are closed to each other and to “minus”. The motor stops for a few seconds and then the cycle repeats.

Why the wipers don't work

At some point, the car owner may notice that his wipers are not working. This may manifest itself in their complete stop or creaking operation.

Trapezoid Compatibility

First of all, look for the reason in the electric motor. But remember that mechanical problems also happen.

The most popular mechanical breakdowns of wipers:

• When the cleaners turn on, the sound of the motor is heard, but the brushes do not move or twitch slightly. Most likely, the nut securing the crank to the gearbox axle has lost its grip or has become completely unscrewed.
• Non-synchronous operation of the windshield wipers indicates a problem with the drive. Again, check the locking nut. When tightening the nut, be sure to first place the brushes in the correct position.

As for problems with the electrical component, they manifest themselves as follows:

• The wiper moves very slowly, stops, then starts working again, does not stubbornly go to the lower position. Check the limit switch. By bending the contacts, it is adjusted in this way. If such a measure does not bear fruit, replace the entire VAZ 2110 wiper motor assembly, since the gearbox is built-in;
• You have turned on the intermittent mode, but the brushes work non-stop. Here the problem lies in the relay, which needs to be replaced. If when you turn on the device you do not hear a sound from the rotation of the motor armature, then the relay is 100% to blame. If not, then check for burns and oxidation on the contacts;
• When choosing any mode, you can only hear the clicking of the thermometallic fuse. At the same time, the anchor and brushes remain in place. Check to see if the brushes are frozen because of the frost and that’s why they don’t move. Either fuse F5 has blown, or the armature has burned out;
• The electric motor does not turn on, although the fuses are good. Check the quality of contacts. This often causes a stuck brush or a burnt armature.

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.

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.

Windshield wiper repair

In practice, repairing wipers on a VAZ 2110 is not at all difficult if you have at least basic experience in working with a car and its electrical components.

Unscrew the fixing nut

First, let's figure out how to remove the wipers on a VAZ 2110. The design provides several fasteners, by unscrewing which you can easily remove the wipers themselves.

But with disassembling the windshield wiper assembly, everything is a little more complicated. It is analyzed as follows.

1. Remove the dashboard.
2. On the left side, find the relay that is attached to the body. If it is broken, there is no point in repairing it. Just install a new relay.
3. Next, check the condition of the fuse that controls the operation of the windshield wiper drive.
4. Disassemble the steering column to allow you to examine the state of the switch. If the insulation is damaged or there is other damage, replace the unit.
5. Unscrew the electric motor from the body and check it in action. If the damage is not serious, it can be repaired. It's better to immediately replace it along with the relay.
6. Check the drive. It is not uncommon for a pulley to break on it, which is why the device has to be replaced with a new one.
7. Make sure the trapezoid is in good condition. It may be necessary to replace the windshield wiper trapezium on a VAZ 2110 if, during operation of the car, the lubrication of the device has deteriorated and all kinds of debris and water have gotten in there. If the lubrication does not work properly, the plastic bushings of the hinges wear out, causing play and increasing resistance during operation of the device. The trapezoid itself serves to transmit force from the electric motor to the windshield wiper arms.

Refinement stages

Wiring

It is easy to modify or replace wipers. To do this you need to take several sequential steps:

• Disconnect the negative cable from the battery;
• Pull the wiper towards you;
• Remove the existing brushes;
• If there is a decorative trim, remove it;
• Unscrew the mounting bolt, thereby removing the old wiper;
• Compare the dimensions of the old and new cleaner;
• Ideally, the new device should not exceed the old one by more than 20 millimeters;
• Reverse the assembly procedure.

As you can see, changing windshield wipers is not difficult. But with the repair procedure, everything is somewhat different. But following the instructions, even an inexperienced VAZ 2110 owner will be able to do everything with his own hands.

Today, no one can be surprised by the presence of a family’s own car. Manufacturers are trying to make their “product” as safe as possible, and this applies not only to the engine and the components that provide movement. The issue of safety sometimes directly depends on the cleanliness of the glass. If the windshield and rear windows are not clean enough, or are covered with drops of water or snow, then you will strain your eyes more and more to fully see the situation on the road. After an hour of driving like this, your concentration will decrease, and this threatens an accident. How can you make sure nothing bad happens? The correct answer is to monitor the condition of the windshield wipers, in particular the trapezoid. This is what we will talk about.

Useful information about the windshield wiper trapezoid

The most important element of the windshield wiper system is the trapezoid. It is this element that is responsible for converting the rotational movement from the electric drive shaft into the translational movement of the wipers. If the trapeze works correctly, then the safety of your movement in bad weather conditions will be ensured. The design of the windshield wiper is quite simple, but reliable and wear-resistant. The main elements of the system are:

- brush and leash;

The design of the trapezoidal wipers on cars from different manufacturers is almost the same. The difference can only be in the dimensions and shape of its various parts. The main elements that create this node are:

Using calculations, designers determine what the profile of the trapezoid links should be. Thanks to this, the structure forms the necessary safety margin, that is, the integrity of the system is maintained when the brushes move. In order to minimize losses due to friction, and to optimize the energy consumption of the electric drive, the trapezoid connecting elements are made of a material based on polyformaldehyde. It produces an extremely low coefficient of friction and is characterized by a high level of wear resistance. To protect metal elements from corrosion, they are coated with a galvanic layer.

When is it necessary to replace the windshield wiper trapezoid?

The incorrect operation of the windshield wiper trapezium, as well as the presence of damage on it, is indicated by malfunctions in the operation of the wipers themselves. For example, they may move too slowly regardless of the operating mode, or stop spontaneously while cleaning the windshield and rear windows. Another clear indication that the wipers are faulty is intermittent movements of the brushes, jumps, and a characteristic sound from the wiper during operation. The main reason for such malfunctions is the presence of oxide on the driver drives in the trapezoid bushings.

It is the oxide that prevents the wipers from rotating normally. If this problem is ignored, then the electric motor, which is subject to a significant load, may also break down, and this entails the possibility of the electric motor’s armature burning out. If there is play in the windshield wiper arms, that is, the arm hits the hood, then rest assured that the trapezoid bushings have worn out.

If you notice even a hint that the windshield wipers are not working correctly, then diagnose the system as soon as possible, and, if necessary, repair or replace the broken unit.

Otherwise, the risk of getting into an accident on the road increases greatly. The need to pay attention to the windshield wiper trapezoid may be indicated by low pressure in the system. If the wipers do not completely remove snow or water, then there is a problem with the pressure.

In order to understand what exactly needs to be done with the trapezoid - change or repair - it is necessary to carry out diagnostics. If you decide to replace the trapezoid, then the new mechanism must be selected correctly. Two trapezoids from different manufacturers can be very similar in appearance, but attached in different ways. The sizes of the leads and the types of connectors for connecting to the electric motor can be different. The conclusion from all this is simple - buy a trapeze from the original manufacturer specifically for your car model.

Alternative solutions

Most car owners of the domestic “ten” are accustomed to replacing worn out and faulty windshield wipers with similar ones.

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.

Today it is fashionable to use frameless wipers, especially from Bosch. Their advantages lie in their compactness and a special, reliable leash mechanism.

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.

How to determine that a trapezoid is “kirdyk”

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.
