VAZ 2114, 2115, 3113 wipers do not work: operating modes and windshield wiper circuit, causes of failure

The service life of the wipers on the VAZ-2115, as on any other car, is designed for a long service life. Various malfunctions, as a rule, appear due to improper use of this mechanism. Typically, such troubles occur in winter, when the blades simply freeze to the glass, and the driver, without noticing this, turns on the electric motor that powers the wipers.

Both the electrical and mechanical components of the windshield wipers can break down. Further in the article we will tell you about the features of troubleshooting wipers on a VAZ-2115.

Advice for car enthusiasts

When replacing windshield wipers with new ones, you should give preference to modern, frameless models.

They have such advantages as:

• higher reliability (compared to classic models);
• increased service life;
• absolutely silent operation (there are no squeaks common for frame wipers);
• effective cleaning of contaminants.

Such wipers will not only do their job more efficiently, but will also significantly transform the appearance of the car.

What does the VAZ 2114 fuse box look like?

The fuse box of the VAZ 2114 is the part that prevents the occurrence of a malfunction in the vehicle's electrical system - a short circuit. This vehicle has 2 independent fuse blocks. One is under the hood, the second is in the car interior on the left under the steering wheel. In the VAZ 2115 and other cars of this series (after the “ten”) the location of the block is identical, so there will be no problems finding it.

Fuse box diagram

The VAZ mounting block, which is located under the hood, is the main one. It is there that the fuses are located, which are responsible for the operation of the engine itself, the switch, the ignition coil, etc. But if the cigarette lighter on a VAZ 2114, the cooling system impeller, the stove or the dashboard backlight does not work, then you need to look for a damaged fuse under the steering wheel - namely there are keys for these electrical circuits.

The fuse diagram of the block (Image 1) under the hood is available on the body itself. It is enough to remove the cover near the windshield in the driver's area and look inside at the schematic diagram of what each of the fuses is responsible for. This connection diagram allows you to accurately determine which of them has burned out if one or more electrical devices do not work. There is also space for installing spare fuses. It must be taken into account that they are not the same. For example, the one that is responsible for the operation of the generator is rated at 15A, while the fuse that closes the audio signal circuit can withstand up to 30A. Those for side lights - 7.5A. And glass lifters are designed for 20A.

Repair

To troubleshoot problems with the wipers on your VAZ 2109, it is not at all necessary to contact a service station. The work can be done with your own hands, saving a decent amount of money.

Repair consists of performing several operations:

• Disassembling the unit;
• Troubleshooting;
• Eliminating the causes of purifier failures;
• Reassembly.

Dismantling

The first step is to learn how to remove windshield wipers. This will give you access to the device and all its components.

It is enough to follow the specified sequence of actions and first familiarize yourself with the wiper diagram in order to do everything correctly.

Scheme

1. First, disconnect the negative terminal of the battery to de-energize the car.
2. Remove the brush arms by moving them to a vertical position and unscrewing the fastening nuts. Unscrew the nuts carefully so as not to push the lever out. Otherwise, under the action of the spring, it will fly into the glass and break it.
3. By unscrewing the fasteners, the levers can be removed. It is not always possible to do this manually, so arm yourself with pliers. Be careful not to damage the threaded area. To avoid this, screw the nut back onto the splines, but not completely.
4. Remove the protective caps made of plastic from the slots on each side.
5. Unscrew the upper mounting nuts with the bracket and remove them. Under them there are rubber washers, which are also dismantled.
6. Lift the hood and disconnect the wiring harness that powers the wiper motor.

1. Unscrew the heater fan mounting screws and move it slightly to the side. This way, when dismantling the purifier, it will not interfere with you.
2. Remove the cover from the relay and fuse box. You need to remove not only the wiper relay, but also everything else. Otherwise, they will interfere with your further processes.
3. Unscrew the lower fastening nut of the mechanism, remove the plastic holder of the wiring harness from the electric motor from the hole in the car body. Now you can remove the holder so that it does not get lost during the repair.
4. All that remains is to push the mechanism roller inside, then lift the electric motor and the windshield wiper mechanism slightly up and to the side. This way you can easily remove the node.

Possible problems with front wipers

• Not a single wiper mode works, you can’t hear the gear motor operating.
• The intermittent wipers do not work.
• The wipers work slowly (poorly).
• The wipers (brushes) do not move, the gear motor works.
• The wiper switch does not work.
• The wipers do not return to their original position.
• The wipers do not work when the washer is turned on.
• Windshield wiper blades do not clean well.

Replacement/removal of windshield wiper elements:

• How to remove a trapeze?
• How to remove the windshield wiper gear motor?

Replacing the motor

In practice, replacing wipers on a VAZ 2114 may be necessary in several cases. The most common is the failure of the gear motor.

There are different reasons:

• The brushes constantly work, the shutdown relay does not work;
• Turning on the regulator does not allow the wipers to start;
• Sometimes the windshield wipers simply do not turn off when the corresponding buttons are pressed, etc.

To avoid breaking the teeth of the new gear motor due to the crank (the curved rod that connects the motor and the trapezoid arms), proceed in the following sequence:

1. Turn off the safety block.
2. Mark the crank position.
3. Disconnect the crank fasteners.
4. Unscrew the trapezoid fixing bolts.
5. Remove the motor.

Washer problems

Breakdowns and methods for eliminating them are different. Let's get to know them in more detail.

1. The steering column switch does not work. Make sure of this by closing two contacts under the steering wheel - front contact 53ah-w, rear - 53ah-wh, and then measure the resistance. If it is low, the switch is replaced with a new one.
2. There is no water flowing through the washer pump. It should also be replaced.
3. Dirt has formed in the injectors. Use a sharp needle to clean them.
4. The wire that connects the pump and the switch has broken. You understand that the only option is replacement.
5. Relay K3 is faulty. Again, you have no choice but to change the relay.
6. The hose ruptured and its integrity was compromised. What do you think should be done in such a situation? Absolutely right - change the hose.

Causes of malfunction

The reasons why injection-type wipers on the VAZ 21099 do not work are no different from those why carburetor wipers do not work.

1. The fuse in the mounting block has blown.
2. Relay is faulty.
3. The steering column wiper switch needs to be replaced or repaired.
4. The bimetallic fuse has tripped.
5. The wiper motor is broken.
6. The graphite brushes inside the motor are stuck or worn out.
7. The contacts in the electrical circuit connectors have jumped off or oxidized, as well as other problems with the wiring.
8. The mechanism itself is worn out or bent, fastenings are loose or unscrewed, and the teeth on the gears of the gearbox are damaged.
9. The windshield wiper limit switch does not work.

Why did the wipers stop working on the VAZ 21099?

It happens that one not too wonderful day your car presents another surprise. Of course, often a lot depends on the age of the car, weather conditions and how the car is used! But sooner or later the turn comes to the windshield wipers, popularly called wipers.

So why don’t the wipers of your VAZ 21099 work? A number of malfunctions are possible, from the simplest ones, which many are able to fix on their own, to more serious breakdowns, when the help of a specialist is required to diagnose the malfunction and solve the problem.

Common causes of malfunction

Why did the wipers start working slowly? This question is asked most often among VAZ owners. It just so happens that almost all cars of the 2109 model suffer from this disease. So why do the wipers not work? Why does the system wear out so quickly? Below is a list of the most common windshield wiper problems:

1. Damage to system levers. Even a slight change in the shape of these parts can affect the speed of the mechanism.
2. Faulty power cords. If there is not enough electricity supplied to the system, it is no wonder that it will slow down.
3. Foreign objects in the mechanism. Any pebble or blade of grass that accidentally gets into the device can cause serious damage, not to mention slowdown.
4. The blades are frozen to the windshield. In winter, you need to pay especially close attention to the mechanism if you do not want to tear off its frozen parts from the glass.
5. Short circuit in the winding or excessive contamination of parts. The structure must be carefully monitored; it must be cleaned from time to time and the winding changed if necessary.

But all these malfunctions most often have nothing to do with the slowing down of the windshield wipers on the car. Experienced car owners have long figured out what the true cause of windshield wiper failure is. Most often, the reason is that drivers do not take good care of their car. The VAZ needs especially close attention due to its design.

Dimensions

In fact, the size of the wipers on the VAZ 2114 plays a fairly large role in the quality and efficiency of glass cleaning.

Windshield wiper wiring diagram

Small brushes are also not good, because then the cleaning area is reduced and not the entire glass surface is cleaned, which would provide the required visibility for the driver.

Then what should be the size of these same brushes in the case of the “fourteenth” model?

• The windshield of the VAZ 2114 has two blades of the same size - 51 centimeters. The brush on the driver's side can be replaced with an element 53 centimeters long, but on the passenger's side it is important to leave 51 cm. Otherwise, a strip of cleaned water will remain on the glass between the driver and passenger.
• There is also a cleaner on the rear window of the VAZ 2114. But in this case, the size of the element is 30 centimeters. It is possible to install the wiper at 33 centimeters, which allows it to fit perfectly into the dimensions of the rear window. Some even install components at 40 centimeters, but in this case you will definitely have to increase the wiper stroke limit. To do this, remove the motor, shift the teeth by several units and put it in place.

Electric motor or gearbox

Useful : Detailed diagram of VAZ 2114 wipers

The most serious failure in the design of purifiers can be a malfunction of the electric motor and gearbox. Checking the motor is simple - remove the rods and connect it directly to the battery using wires. If there is no result or there is a grinding and noise during its operation, replace the motor with a new one. Under normal operating conditions, the gearbox is considered a fairly reliable element that rarely becomes unusable. The price of a new motor starts from two thousand rubles or more. It’s not worth buying a used motor with a gearbox, because... It is difficult to externally determine the service life it has served.

The working gearbox of the windshield wipers sets them in motion at high speed, so weak movement of the wipers along the glass can signal an imminent breakdown. A tip to increase gearbox life is to avoid moving the wiper blades by hand. Also, do not use them to clear frozen ice and snow.

How the windshield wiper works

On VAZ 2108, 2109, 2113, 2114 (hatchback body) cars a windshield wiper and rear window washer are installed. 2115 models there is no rear window wiper.

Electrical diagram of the rear wiper:

Windshield wipers have several operating modes: intermittent (work with a pause), low (first) speed, high (second) speed, one-time triple cleaning of the glass, operating mode with a windshield washer. The rear wiper operates only in one position and in conjunction with the rear window washer.
