Replacing the windshield wiper trapezoid (windshield wiper) on a VAZ 2110, 2111, 2112 may be required quite rarely, but still, after several years of using the car, car owners are faced with the fact that the trapezoid begins to work either intermittently or completely refuses to wave the windshield wipers in a heavy downpour. It is in this case that you will need to remove the trapezoid and see what the reason is... Perhaps the splines are eaten away, or maybe the motor is covered - it happens in different ways. Next, let’s look at how the wipers of a VAZ 2110, or rather the trapezoid, are replaced.

And so, in order to get to the trapezium of the wipers, you first need to remove the wipers themselves, and then remove the frill (unscrew the 4 fastening screws at the top and 7 at the bottom, as well as 2 nuts in the corners). To make it easier to access the windshield wiper trapezoid, you will need to remove the insulation trim in the engine compartment and move the expansion tank to the side. Then unscrew the nuts securing the trapezoid and the drive motor (two bolts on the sides and one on the bottom, and also disconnect the power plug for the wiper motor). Then, removing the trapezoid from the studs, turning it, we pull it out. Install in reverse order. It should be noted that for the tenth family two types of trapezoids are installed: old and new models.

The windshield wipers of the VAZ-2110 car themselves do not represent anything structurally complex. However, their failure, especially during heavy rainfall, can trigger an emergency situation. One of the main elements of windshield wipers or “brushes” is a trapezoid.

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.

Windshield wiper repair

To repair the unit you will need the following materials and tools:

• set of sockets and keys;
• screwdrivers;
• WD-40 liquid;
• old rags;
• trapezoid repair kit in case of need for replacement or windshield wiper repair kit for VAZ 2110;
• other parts requiring replacement.

To repair the windshield wiper, you need to disassemble it:

1. First you need to remove the instrument panel.
2. Next, you should find the VAZ 2110 wiper relay, which is screwed to the body. If it doesn't work, it needs to be replaced.
3. It is advisable to remove the frill so that it does not interfere with disassembling the unit.
4. Now you need to check the fuse that is responsible for the operation of the VAZ 2110 wiper drive.

The next step is to disassemble the steering column to check the switch. If it has significant damage, it needs to be replaced (the author of the video is “In Sandro’s Garage”).

1. Next, you need to dismantle the motor and check it. If replacement is necessary, replace the windshield wiper motor and gear motor assembly.
2. If the windshield washer reservoir or pump is damaged, it must be replaced.
3. Be sure to check the size and condition of the brushes: they must meet the standards specified in the manual. Their length is important as they must cover the entire surface of the windshield.

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

The weak point of this motor is that there are a fairly large number of contacts along the power circuit. This affects both the voltage and the possible causes of malfunctions: the contact on one link of the chain is lost or unstable, and stable operation of the windshield wiper is no longer possible. In this case, it is quite possible that the motor is not at fault. Therefore, before you decide that it needs to be replaced, check the contacts along the entire circuit.

• Fuse. Pay attention to the fuse, it may also be faulty;
• Performance. Next, you should check the switch itself for serviceability;
• Operating parameters. Using an ohmmeter, check the resistance in the circuit breaker between the terminals. If it shows “zero”, you need to change the breaker;
• Correct connection. Without turning on the wiper, measure the resistance between the fourth terminal and ground. It must also be zero. Otherwise, you need to properly restore the grounding;
• Voltage. Turn the windshield wiper to low speed and check the voltage at terminal five. It is equal to the battery voltage, but the gearmotor does not work? It needs to be changed.

Causes of malfunction of the VAZ 2110 windshield wiper motor

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.

Brushes

Standard VAZ-2110 brushes consist of three elements:

The frame of the device is made of metal and has a composite structure, which includes one main rail and two additional ones located on it. The brush is made of soft rubber. In the middle of its working surface there is a longitudinal protrusion (keel), which, in fact, cleans the glass. The brush is attached to two additional frame slats, fitting into their grooves. To ensure that the wiper slides easily across the glass, some manufacturers coat its working part with graphite.

In the center of the main rail there is a fastening mechanism with which it is attached to the leash. It is a guide into which the hook of the leash hooks and a plastic latch that secures the connection.

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 that will 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.

Only after this can the trapezoid be removed. The main thing is not to forget to disconnect all electrical connectors.

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.

Replacing the motor and windshield wiper trapezoid

Design of a windshield wiper on a VAZ 2110

it is quite reliable and during normal use the motor and the trapezoid itself can quietly move away for 300,000 km, which has been confirmed by the personal experience of many owners. But there are also exceptions to the rules.

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.

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.

Photo report on the removal and installation of the windshield wiper trapezoid on a VAZ 2110-2112

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. Publication 'Repair kit for windshield wiper trapezoid VAZ 2110': Repair of trapezoid. Chinese analogues cost about 2000 rubles.

Which brushes to choose

Having decided on the size of your wipers, do not rush to buy the first model you come across. The fact is that the auto parts market today is filled with fakes. By skimping on some 100 rubles, you can buy wipers that will work effectively for several days, and after that they will begin to creak and let water through. It is better to give preference to well-known manufacturers and make the purchase in a specialized store. As for the design, it’s up to you to decide whether to purchase “frameless” or regular ones. The main thing is that the fasteners fit.

The QG16DE engine uses a phased distributed fuel injection system. This means that each cylinder uses its own fuel injector (port injection), and fuel injection is carried out by the injector only of the cylinder in which the intake valves are in the open position (phased injection). The amount of fuel injected varies depending on the duration of the electrical pulse supplied to the injector solenoid valve from the electronic engine control unit (ECU). In general, the electronic engine control system performs the following functions:

• control of the moment and duration of fuel injection; • control of energy accumulation time in ignition coils and regulation of ignition timing; • regulation and maintenance of engine idle speed; • electric fuel pump control; • control of electric radiator cooling fans; • control of the air conditioning compressor clutch; • control of the solenoid valve for purge of the adsorber of the gasoline vapor recovery system; • control of the “CHECK ENGINE” indicator lamp; • interaction with a standard car anti-theft system (ATS) or immobilizer; • generation of diagnostic trouble codes and interaction with an external diagnostic device; • generating signals for the trip computer; • integrated engine/automatic transmission control to reduce shock when changing gears by reducing engine torque; • emergency operation mode, which allows you to continue driving if individual components of the ECM fail.
