How to change the rear wiper of a VAZ 2114 to the correct size


How to remove the rear window wiper (rear wiper)?

Samar models such as VAZ 2113, 2114 are equipped with a rear window wiper. But it happens that the wiper motor, drive teeth, etc. break. In this case, you will need to disassemble and remove the windshield wiper mechanism, and we will help you with this. But before that, you need to find the exact problem, so we suggest you familiarize yourself with other causes of the malfunction: The rear windshield wiper (wiper) does not work. What to do?

How to remove the rear wiper?

To remove the wiper, you need to do two steps:

  • remove the wiper itself from the top of the trunk lid;
  • remove the wiper motor/gearbox from inside the trunk lid.

Let's look at these two steps in more detail below:

How to remove the rear wiper?

We will need: keys for “10”, “24”; flat screwdriver.

  1. First of all, use a flat screwdriver to lift the protective cover of the wiper arm mounting.
  2. Using a “10” wrench, unscrew the fastening of the windshield wiper arm and remove the arm itself.
  3. Next, using the same flat-head screwdriver, remove the black O-ring. (Pay attention to the condition of the O-ring: if it is cracked or burst, it needs to be replaced.
  4. Then, using a “24” key, unscrew the nut that appears, securing the motor to the trunk lid. Remove the sealing rings. If the rings are damaged, they must be replaced. Damaged o-rings can cause water to penetrate into the gear motor, resulting in its failure.

Also pay attention to the condition of the teeth of the gear motor rod: if the teeth are worn out, then this is the reason for the wiper not working: the gear motor turns, but does not engage the wiper, but slips.

How to remove the gear motor?

  1. Open the trunk lid and remove the plastic trim, having first pulled out the clips that secure the trim.
  2. Disconnect the wiring block from the gear motor.
  3. Using a key set to “13”, unscrew the two fastenings of the gear motor and remove it.

How to install a rear window wiper?

Installation proceeds strictly in the reverse order, after first replacing the rubber seals. Also, when installing the casing, it is recommended to use new clips, since they are inexpensive.

Tips for use

  1. Before use, it is advisable to treat them with soapy water.
  2. Monitor the quality of liquids with which the brush comes into contact during its operation, use them only in accordance with the instructions.
  3. Rinse frequently with water to remove large dirt particles.
  4. Lubricate the hinge joints periodically.
  5. Prolonged exposure to frost and sun will shorten its service life. And therefore, in the summer, when parking for a long time, it is better to cover the car or at least cover the windshield. And in winter, the car should be in the garage.
  6. Wash your windshield more often; this service is free at many gas stations.
  7. If the glass is covered with ice, do not use windshield wipers; it is better to clean it manually with a special scraper.
  8. In cold weather, during long periods of inactivity, you need to raise the wipers so that they do not freeze.
  9. Try to buy brushes only from well-known manufacturers, they will pay for themselves.
  10. It is not recommended to use windshield wipers without windshield washer.

These tips will help many beginners save money. After all, simple car maintenance work can be done on your own. This is both more pleasant and more reliable sometimes. We wish you to see the road equally well in any weather. Safe and clear road!

Replacing the rear wiper and wiper blade

This procedure will be necessary for all car owners who have a rear wiper, either a station wagon or a Lada Kalina hatchback. For this work you will need a 10 mm wrench and a screwdriver (any).

How to remove the windshield wiper

First of all, we need to lift up the protective metal cap, under which there is a fastening nut.

After that, take a 10mm wrench and use it to unscrew the nut. Please note that there is a small washer under it to prevent it from being dropped. Moving the wiper a little, we pull it towards ourselves and it can be removed without much difficulty.

Removing the rear wiper blade

The whole procedure is carried out with the wiper removed, it’s not all very convenient to do, but it won’t be difficult to figure out. You need to pull the brush itself, and at the same time use a screwdriver to slightly release the latch, which is marked in the photo below with a yellow arrow.

Putting it back is much easier; you just need to insert the brush into the place where it is attached and press with a little force until it clicks.

Windshield wiper trapezoids


Replacing the Windshield Wiper Trapezium The main reason that you need to replace the windshield wiper trapezoid is the slow operation of the wipers. The trapezoid is also replaced in case of serious mechanical damage. To replace it, you must adhere to a certain technological sequence.

  • Under the hood, the wires connected to the fuse block are disconnected.
  • The protective casing covering the heater fan is removed.
  • The stove filter is removed.
  • The heater motor is disconnected. You just need to move it to the side, there is no need to remove it.
  • The decorative trim is removed from the wipers.
  • Under the protective rubber cover there is a nut that secures the windshield wiper.
  • The cover lifts slightly and it unscrews. The janitor is removed.
  • The wiper shaft is freed from rings and gaskets.
  • The second windshield wiper is removed in the same way.
  • Under the hood, the bolts securing the trapezoid to the body are removed.

It will not be possible to immediately pull out the released trapezoid. The fuse box will interfere, as well as the heater motor. To remove the trapezoid, you can use two exits.

  • Remove the fuse box by unscrewing the nuts securing it, and remove the heater motor.
  • Disconnect the gear motor from the trapezoid. Remove the gear motor one by one, and then the trapezoid.

When disconnecting the gear motor from the trapezoid, it is necessary to remember and mark the location of the crank. A marker will be useful for this purpose. Only after this can you unscrew the mounting bolts and disconnect the motor from the trapezoid.

What types of rear wiper blades are there?

A car is an expensive pleasure. And this is not at all connected with its market value, but with the need to periodically replace all consumables and parts. This even applies to windshield wipers, or wipers, as we used to call them. After all, the constant interaction of windshield wiper blades with dust, dirt and water leads to their wear. And in a worn-out state, they are as useless as milk from a goat. Well, driving a car with dirty windows is the same as driving with your eyes closed.

So car owners have to go to a special store and buy wiper blades. Fortunately, at least their replacement can be done without outside help and expensive professionals. So today we decided to help you in a similar situation and tell you how to replace the rear wiper blade.

We study the causes of rear wiper blade wear

If a car is used regularly and under a variety of weather conditions, as well as on sections of the road of varying complexity and pollution, over time even its main “organ” - the engine - wears out. Therefore, wear of the rear windshield wiper blade should not surprise you, especially since they always have to interact with external conditions. What role do windshield wipers play on a car?

The immediate task of these devices is to provide a good view of the space in front and behind the vehicle. In turn, this factor is directly related to road safety. So the windshield wipers, just like the seat belt, are the most important elements of the car that save the life of the driver.

Why do we turn to the rear windshield wiper and not the front ones? If you are an experienced car owner, you have probably noted more than once that it is the rear wiper blade that wears out faster, which is why it has to be replaced more often. And since the rear and front windshield wiper blades are attached almost identically, a description of the process of replacing one will help you successfully cope with replacing the other.

A variety of reasons can lead to wear of the described parts. This is mainly due to the aerodynamic features of the car. While driving, the wind blows dust and dirt off the windshield. Even raindrops can fly off of it on their own. At the same time, all this is carried back and settles on the rear window. Also, dust constantly flies here from under the wheels of the car, and particles of fuel and lubricants from the exhaust pipe settle. So it turns out that the rear wiper has to work two or even three times more intensely than its front brothers. And the driver is forced to change the rear windshield wiper blades from time to time.

Main problems

Signs by which you can understand that the VAZ 2115, 2113 or 2114 generator brushes need to be replaced are:

  • the battery does not charge or runs out of power quickly;
  • warning lights on the dashboard are flashing;
  • voltage failures;
  • on-board electronics turn off or there is not enough power for its operation;
  • the headlights begin to flicker or their light has become dim.

All these signs indicate brush wear. The following message appears on the instrument panel.

Why the VAZ-2114 wipers don’t work and what to do


The windshield wipers on a VAZ car must ensure that the windshield and rear glass are cleared of precipitation that prevents the driver from concentrating on the road. If the windshield wipers do not work on your VAZ-2114, then it is unsafe to drive onto the road in rainy weather. To quickly solve the problem, you can try to repair them yourself. Any successful repair requires knowledge of the design of the broken unit.

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?

  1. 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.
  2. 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.

Design of the VAZ-2114 windshield wiper

The windshield wiper on the VAZ-2114, as well as on other models, consists of the following components:

  • drive (electric motor with a long shaft);
  • gearbox;
  • lever system (trapezoid).

It is the last part that drives the wipers.

A worm is cut into the front of the electric motor rotor, which drives the main gear of the gearbox. When the windshield wiper turns on, voltage is supplied to the electric motor and the shaft begins to rotate, driving the gearbox. Thanks to it, the levers move, to which the ends of the wiper housings, located on the outside of the car body, are attached. There is a special hook at one end of the shaft. With its help, the moving contact of the windshield wiper stops in the extreme position is controlled.

Reasons why wipers fail

The service life of automobile windshield wipers is determined by:

  1. The quality of the materials used in their manufacture.
  2. Conditions of use.

The elastic materials from which wipers are made fail as a result of prolonged exposure to:

  • solvents included in the special liquid poured into the car washer reservoir;
  • chemical reagents that utility services use to clean road surfaces in the winter;
  • active chemicals used in car washes;
  • high and negative temperatures;
  • ultraviolet radiation (direct solar radiation).

As a result of the influence of all these factors, the material of the windshield wipers loses its elasticity over time, becomes cracked and no longer adheres tightly to the windshield.

The need to replace car windshield wipers is determined by the presence of water residues on the windshield during rain, snow or mud.

Wiper control

The wipers are controlled from a switch mounted on the steering column, which allows the wiper to operate in several modes, necessary in different weather conditions. The VAZ-2114 car has three types of wiper movement:

  • intermittent mode;
  • constant low speed of movement;
  • constant high.

Often in VAZ cars the windshield wiper does not want to work in only one mode, so you need to know not only the design, but also the mechanism for controlling the glass cleaning system.

Intermittent mode begins to operate in the first and second positions of the switch. A relay located on the circuit board of the car and designated in the diagram as “Short circuit” is responsible for its operation. In the third position of the switch, the wipers operate in constant mode at a low speed. To switch the wiper to constant high-speed mode, you need to turn on the fourth position.

Do-it-yourself replacement of the Lada Granta windshield wiper drive - step-by-step instructions

1. First of all, remove the wipers. This is done in the following way: it is necessary to remove two decorative plugs, under which there are mounting nuts with a key size of “13”, they must be unscrewed, and the windshield wipers must be removed from the slots along with the brushes and leads.

Note: After removing the wipers, do not turn them on so as not to have to worry about adjustments during assembly.

2. Next, you need to remove the frill (decorative plastic trim), for this you will need an “asterisk” - TORX T20.

Note: Some mounting screws are hidden under decorative caps.

3. Using a “10” key, you need to unscrew the nut (on the right), as well as 2 bolts (on the left) securing the trapezoid.

4. Now you can turn off the power; to do this, disconnect the wire from the battery and disconnect the connector. Now you can safely remove the entire trapezoid assembly.

5. Next, everyone can do their own depending on the need, some will have to replace everything, and for others it will be enough to wash everything and lubricate it properly.

6. After completing all the necessary work, you can perform assembly; it is performed in the reverse order.

The new trapezoid works properly, while the cleaning area has increased (within the limits of what is permitted), it does not rub or touch anything anywhere

Causes of malfunction and their elimination


It often happens that the wipers do not respond to switching modes. If you turn on the wipers and when you switch the lever you do not hear the sounds of the electric motor or the clicks of the relay, the reason may be hidden in three places:

In such a situation, you first need to check the functionality of the fuse. It is located on the circuit board designated F5. You can check its working condition using a conventional tester. You also need to check the bimetallic fuse located in the purifier gearbox. If the wipers on a VAZ-2114 stop working in winter, there is most likely one reason - severe frost. The same fuse prevents the windshield wiper from turning on in case of overheating or freezing of the blades to the windshield.

Where is the generator located?

Engine VAZ 2114

How to change brushes on a VAZ 2114 generator? Before answering this question, let’s determine where the patient himself is. This is the simplest, but at the same time difficult question, because the generator is under the hood. But when you open it, the alternator is not visible there, because it is attached to the bottom of the engine and connected to the crankshaft by a separate belt. To see it, you need to be in front of the car and look into the left side of the hood behind the engine. There you will also find a belt tensioner.

To easily replace the brushes, it is necessary to dismantle the generator, because this will allow you to check it more thoroughly as a whole. But if desired, this can be done without removing it. But then a number of problems arise that are associated with limited space and the inability to support anything with the second hand if necessary. In addition, you must be 100% sure that the problem is only in the brushes.

Removing the generator

Before starting to work with the elements and devices of a machine powered by electricity, it is necessary to disconnect the negative terminal from the battery.

In order to remove the generator, you need to loosen the tension bolt or mechanism and move the generator towards the engine with a pry bar or a large screwdriver. After which the belt can be easily removed. Next, you should loosen the mounting bolt with a head of 17. And freely remove the generator. Of course, before removing the generator, it is necessary to disconnect all terminals and wires from it.

Replacing brushes

Generator brushes VAZ 2114

Replacing brushes on a VAZ 2114 consists of the following sequence of actions:

  • disconnect the negative terminal from the battery;
  • disconnect the block with wires and the protective rubber cap;
  • unscrew the clamping nut and remove the power wires from the stud;
  • release three latches around the perimeter of the round plastic cover;
  • remove the cover and find the regulator with brushes in the water body;
  • unscrew the mounting bolts of the brush device;
  • remove the brushes with the regulator;
  • take new brushes and measure the size of the protruding graphite contacts, it should be at least 1 cm;
  • if the size corresponds to the required one, then it is necessary to check the regulator itself;
  • take new brushes and perform all the steps in reverse order.

When the relay is triggered, the electric motor does not start

The cause of failure of the electric motor may be either a blown fuse or the motor itself. Fuses must be tested for functionality. If they are in working order, you need to inspect the trapezoid located under the hood; perhaps it has become deformed or a foreign object has gotten into it. In severe frost, again, you should check whether the blades are frozen to the windshield.

If the trapezoid is normal and the wiper blades move freely, you should definitely check the electric motor. To exclude other malfunctions, it should be removed from the car and connected directly to the battery. If it starts working, then it’s time to look for the cause in the electrical circuit.

Deciding on a place

It is, of course, best to install frameless wipers in a garage or other covered area. You should place the necessary tool next to you; you won’t need much of it – just a couple of screwdrivers.

how to change frameless wipers
It is best to install wipers in the summer or, if it so happens that it is already cold outside, in a heated room. Firstly, some parts and fasteners are very small. And secondly, when installing or replacing wipers, it will be necessary to rinse the fasteners with water, which will immediately freeze in an unheated room in winter, which will significantly complicate the procedure.

Why does the rear wiper of the VAZ 2109 not work? Troubleshooting and repair

Windshield wipers, wipers, brushes are essentially the same thing. As a rule, we remember their existence only when it starts to rain or when another bird flying by promises us great wealth right on our face :-). It is then that we remember the existence of these miracle devices that can so easily and effortlessly do all the dirty work or simply provide us with normal visibility in the rain, necessary for safe movement.

According to the “law of meanness,” the wipers will stop working exactly at the moment when it rains, snows, or when the glass needs cleaning. But this doesn’t make it any easier; the fault needs to be eliminated, but before that it wouldn’t hurt to find it. In practice, it turned out that finding the reason why the engine does not start is much easier than understanding why the rear wiper of a VAZ 2109 does not work. To be honest, at first, I didn’t even know where to start and what to actually check, the mechanism is as simple as “two rubles” and what -there can be no failures, but the fact remains that the wiper does not work and does not react to anything.

As you may have guessed, today we will talk about the rear wiper, or more precisely, about why the rear wiper of the VAZ 2109 does not work.

So, let's figure out what, how and why.

Windshield wipers do not work: the motor turns and the blades are in place:

  • The reason for this may be poor contact or severe wear of the gearbox drive shaft.
  • The nut securing the trapezoid to the drive has come loose.

The rear wiper does not work and there is no sound from the motor:

  • Perhaps the steering column wiper switch has failed. Check the voltage on the wires with a tester.
  • The windshield wiper drive (motor) itself has failed.

How to replace wipers on a VAZ 2113-VAZ 2115?

Note! All wipers that are installed on cars of the Samara 2 family are replaced absolutely identically, that is, the front wipers are replaced in the same way as the rear one and there is not much difference in this (Only if your wipers are not different, if they are different, then the replacement accordingly will be a little different will be produced differently, but in general everything is done identically), so an example of replacement will be shown only on one front brush, by the way, when you choose a new brush for your car, try to take the same sizes (This is if you want to install a non-original one, just if dear, then you don’t even need to look at anything, it will fit 100%) as well as your old brushes, because if you go too far with the sizes, then when the brushes work, then they will touch the body, in addition to all this, they will There will still be connections with something to tear off from the central part, and this is already poor cleaning of the glass and most likely you will immediately replace the brushes with new ones!

Causes of rear wiper malfunction

  1. Steering column switch not working. It’s easy to check: turn on the rear wiper using the steering column switch and look at the voltage at + terminals 1 or 3 on the mounting block (see diagram). If there is no voltage, the steering column does not work . There is another option: we disassemble the steering column and check for a short circuit between contacts 53ah-53H. If there is a short circuit, then the steering column works .
  2. Not working gear motor. Either replace or repair a non-working gear motor. A non-working gear motor means a malfunction of both the motor itself: commutator, brushes, fuse, etc., and its components: crank, teeth. How to replace the rear wiper gear motor?
  3. The problem is in the wiring: either the wires going to the rear wiper gear motor have oxidized or broken. Particular attention should be paid to the weight of the gearmotor and its tightening. It would be better if you cleaned the mass again and attached it to another place. It is also possible that the wire may break at the junction between the roof and the trunk lid.

To check, it is better to check the presence of contact on the rear wiper block using a tester.

As for relay K3, it does not take any part in the operation of the rear wiper, which is a common mistake for beginners in car repair.

Possible washer malfunctions

In order for the wipers to work properly, a constant supply of water is necessary. To automate this process, a washer was made. There may be the following reasons for its failure.

  • The steering column switch has failed. To check this, you need to close the two contacts located under the steering wheel. Front contact 53ah-w, rear contact 53ah-wh. After this, measure the resistance. In case of low resistance or breakdown, the switch must be replaced with a new one.
  • The washer pump does not supply water. It needs to be changed.
  • The wire connecting the switch to the pump has broken.
  • The injectors are clogged with dirt. They can be cleaned with a sharp needle.
  • Relay K3 does not work.
  • The hose broke.

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.

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.
