How to remove the wiper motor of a VAZ 2114

Removal, repair and installation of a windshield wiper

You will need: keys “10”, “24”, screwdriver.
1. Disconnect the wire from the “–” terminal of the battery.

2. Turn both brush arms to a vertical position and unscrew the nuts securing them.

3. Remove the blade arms from the windshield wiper rollers

Note. If the lever cannot be removed by hand, unscrew the lever securing nut without unscrewing it completely so as not to damage the thread. Using pliers, pull the lever off the shaft splines, completely unscrew the nut and remove the lever.

4. Remove one protective cap from both sides.

5. Unscrew one nut of the upper bracket fastening on both sides.

6. Remove the rubber leveling washers from both sides.

7. Open the hood and disconnect the wiper wiring harness connector. Then move the heater fan to the right along the compartment in front of the windshield (see “Removing and installing the heater fan”), otherwise it will interfere with the removal of the windshield wiper.

8. Remove the cover of the relay and fuse mounting block by releasing the cover latches.

9. Remove all relays from the block so that they do not interfere with removing the windshield wiper.

10. Remove the bolt from the lower fastening of the windshield wiper bracket.

11. Squeeze the plastic wire holder and remove it from the hole in the body.

12. Remove the holder from the wires so as not to lose it.

13. Remove the rollers of the windshield wiper mechanism from the holes in the body.

14. Move the windshield wiper so that its motor is in the wide part of the compartment in front of the windshield (heater fan installation location). Turn the windshield wiper and remove the wiper motor from the compartment. Slide the wiper towards the relay and fuse box and remove it from the compartment.

15. Unscrew the nut securing the windshield wiper crank...

16. ...and remove the crank from the gearbox shaft by prying it with a screwdriver.

17. Remove the three bolts securing the gearbox with the electric motor.

18. Remove the two screws securing the electric motor wires and disconnect the wires from the thermobimetallic fuse. Remove the engine from the bracket.

19. Remove the retaining ring from the gearbox shaft.

20. Remove the adjusting washers from the gearbox shaft.

Note. Mark the shims so that when reassembling you install them in the same places and in the same quantity.

21. Remove the three mounting screws...

22. ...and remove the gearbox cover.

Warning! When disassembling, do not unscrew the adjusting screw, otherwise the axial clearance of the armature shaft will be disrupted.

23. Remove the panel from the gearbox.

24. Remove the reduction gear.

25. Remove two screws (the second is located behind the gearbox housing)…

26. ...and remove the two cage nuts.

27. Remove the gear housing with brush holder from the electric motor housing.

28. Remove the armature from the engine housing. After disassembly, blow the motor housing with compressed air to remove carbon dust.

29. Remove the retaining rings from both rollers of the windshield wiper mechanism...

30. ...and adjusting washers.

31. Remove the rods from the wiper bracket and remove the adjusting washers from both shafts.

32. Remove the O-rings from the grooves on both sides of the bracket.

Note. Further disassembly of the rod system is impossible, since the rods are of a non-separable design: 1 – crank; 2 – short thrust; 3 – rod joint; 4 – rollers of the windshield wiper mechanism; 5 – long pull.

33. If the brush springs are damaged or have lost their elasticity, replace them.

34. Check the ease of movement of the brushes in the brush holder. They should move freely without jamming. Replace worn or chipped brushes. When replacing, solder the leads of the new brushes to the brush holder

35. Clean the collector with fine-grained sandpaper if it is dirty or has marks, scratches, etc. If the commutator is badly worn or burnt, replace the armature or gearbox with electric motor assembly. If you find traces of jamming on the armature journals, clean the journals with fine-grained sandpaper.

36. Replace a gearbox with severely worn or broken teeth.

37. Straighten bent rods. If this is not possible, replace the linkage assembly.

38. If the splines or threads of the rollers are damaged, replace the rod assemblies.

39. Clean burnt or oxidized contacts of the self-stop mechanism with fine-grained sandpaper.

40. Replace torn, cracked or loose rubber cushions and other rubber parts.

41. Reassemble and install the windshield wiper in reverse order, taking into account the following:

make sure that when installing the armature into the housing, a thrust ball is installed in the shaft recess;

42. Install the windshield wiper in the reverse order of removal.

How to remove wipers correctly?

Replacing wipers is a necessary operation during windshield wiper repair, which in the future should become a habit for every car owner.
The main reasons for replacing wipers: It is better to replace wipers twice a year, for example, in autumn and spring. If the summer was hot and dry, then the same wipers can be used throughout the whole year.

First, turn the brushes to a vertical position.
Then unscrew the nuts securing the wipers.
After that, the brush levers must be removed from the rollers.
Next, you need to remove the protective caps on each side.
Unscrew one more nut on each side.
Then remove the leveling rubber washers from each side.
Then open the hood and disconnect the harness blocks from the wire blocks. Do not forget to move the heating fan slightly to the right side of the compartment, since it will continue to interfere with us when we then begin to remove the windshield wiper.
We remove the fuse.
We take out all the relays.
Then unscrew the lower mounting bolt of the windshield wiper.
We compress the holder with a wire, pull it through the hole and remove it.
The rollers of the windshield wiper mechanism are also brought out through the hole.
Finally, carefully remove the windshield wiper from the compartment.

Attention! If during operation the windshield wiper leaves streaks, uncleaned areas, spots, gaps or stains, then instead of replacing the wipers, you can only replace the rubber inserts on the blades. You can do all this yourself. For proper replacement, read the instructions that will come with the rubber pad kit.

A gear motor is an ordinary electric motor capable of operating in different modes. In the case of the windshield wiper, it has 3 operating modes: Intermittent, 1st speed, 2nd speed. Also, the gear motor has a built-in bimetallic fuse, which is located either on its body or inside.

Signs of a dead gear motor:

If possible causes are discovered, do not rush to change the gear motor! First, check out the other possible causes of the malfunction by clicking on the link.

To remove the gear motor, we only need to unscrew 4 fasteners! But there are two nuances:

The crank is a curved rod from the motor to the trapezoid rods. If you do not install the crank correctly, there is a high probability of damaging the teeth on the new motor.

Open the hood, disconnect the wiring block from the fuse block to the gear motor.
We remember (indicate with a marker) the position of the crank.
We unscrew the fastening of the piston to the motor with a key set to “13” and remove it.
Using a “10” wrench, unscrew the three bolts securing the gear motor to the trapezoid.
We take out the gear motor.

How to install a gear motor?

After this, disconnect the block and install the motor taking into account the position of the crank mark.

Today we will talk about wipers again, but only this time we will figure out why the windshield wipers do not return to their original position and stop in the middle.

The most common causes of this malfunction are:

How to change the wiper motor on a VAZ 2114

Today I replaced the motor with a wiper, the old one was slowly but surely dying, the wipers could barely crawl across the glass, and the motor made a groaning sound;) I thought I would be tortured to change it, because I changed the trapezoid of the wipers in the fall, I cursed everyone and everything!), but Everything worked out fine, the motor can be removed without removing the trapezoid! We unscrew the 3 bolts that hold the motor on the trapezoid and then the lowest bolt on the trapezoid itself, where the mass is usually still screwed from it, then we bend the trapezoid up (don’t be afraid, nothing will happen to it, I did this twice today, because At first they sold me the wrong motor))) and we take out the motor, it’s clear in the place which way it needs to be turned! And we put everything back together in reverse order!

In the end, the sound didn’t change much from the motor, but at least it became a little more fun, but the speed of movement of the wipers became simply cosmic!)))) In general, I’m happy with the result, I should have changed it a long time ago, even when I changed the trapezoid, I was still assed))))

And yes, a little advice, when buying a motor, either take the old one with you to the store, or measure the diameter of the rod where the trapezoid sits, the first motor was sold to me and its diameter was smaller than on the original one, although it was marked 2115, in the end I bought 2108 - 21099 and the price was 300 cheaper than mine!) And it won’t work like mine to drive in positive weather in winter without wipers to the store to change the engine))))

Hello everyone, my dear readers and guests.

I replaced the wiper motor today, the old one completely burned out(

We unscrew the 3 bolts that hold the motor on the trapezoid and then the lowest bolt on the trapezoid itself, where the mass is usually screwed from it, then we bend the trapezoid up (don’t be afraid, nothing will happen to it, I did this 3-4 times today, because at first they sold me the wrong motor, then they sold me the missing trapeze))) and we take out the motor, it’s clear in place which way it needs to be turned! And we put everything back together in reverse order!

In the end, the sound didn’t change much from the motor, the old one became louder and then I think I’ll get used to it)))

In general, I’m happy with the result, although it’s such a tedious task, especially since pulling out the trapeze generally took 2 hours, while I was going to change it and buy a new one, the time didn’t pass noticeably. In general, you will see everything in the photo)))

Domestic fours, as the VAZ 2114 is commonly called among our motorists, are generally reliable cars. But, like any Russian-made vehicles, they have many shortcomings and shortcomings. Learn more about what malfunctions are typical for wipers, how the VAZ 2114 washer reservoir works, and how to repair the wiper device if necessary.

Device

Wipers on the VAZ 2114 are a fairly simple device. The entire structure includes a wiper arm as well as a rubber gasket.

In general, the cleaning scheme consists of the following elements:

the brushes themselves, designed to clean the windshield and rear windows;
a trapezoid that controls the synchronized movement of the wipers;
wiper motor, which sets the entire structure in motion after its activation via the steering column switch in the car interior;
level sensor - the washer fluid level regulator is designed to control the volume of consumables in the expansion tank.

The operating diagram of the cleaner on the VAZ 2109, in the four it is identical

Possible causes of wiper malfunction

What malfunctions are typical for the glass cleaning system:

The wipers are slow. In this case, it is necessary first of all to diagnose the condition of the trapezoid and, if necessary, repair it.
The steering column switch has failed - according to the diagram, this is the main control element. To diagnose the switch, you should close the two contacts that are located under the steering wheel, and then measure the resistance. In particular, we are talking about contacts 53ah-w 53ah-wh. If the resistance is too low, or if the device has a breakdown, it will need to be replaced.
When the switch is turned on, the wipers start working, but no water flows to the glass. If the problem is the pump, which happens quite often, then it needs to be replaced.
In accordance with the operating diagram, if the brushes do not function, you need to use a tester to ring the wire that connects the switch to the motor. Perhaps the problem lies in a broken wiring.
If the water pressure on the glass is too weak, then it is necessary to diagnose the nozzles. As can be seen from the diagram, the nozzles are designed to disperse the flow of liquid across the glass. When using low-quality water, these elements quickly become clogged with dirt, so you need to try to clean them.
Relay K3 has failed - you just need to change it.
The hose leading from the expansion tank to the injectors has broken. If this is the case, then the hose will need to be replaced (author - PitStopMD channel).

The most common causes of this malfunction are:

The problem is with the contacts. Often the reason for this behavior is the contact group of the gearmotor, or a malfunction of the motor limit switch. Stop the wipers in the middle of their stroke without turning off the ignition, check the voltage at the connector of the wiper wires, it should be 12V. Check the condition of the fuse.

Violation of spline integrity. If the car is not new and the wipers often have to work, then a breakdown of the spline teeth of the windshield wiper blade or simple abrasion of the splines could be the reason that the wipers do not return to their place. Alternatively, the slots may simply click, causing the brushes to simply not return to their original position. As a rule, this breakdown is characterized by the fact that the engine makes noise, and the wipers themselves do not return to their place. It can be treated by replacing damaged gears or simple adjustments. To do this, you need to disassemble the windshield wiper gearbox, adjust the nearest one, lubricate them if necessary, check the contacts or completely replace the gear motor.

Equally common is windshield wiper malfunction associated with improper assembly of glass cleaning elements. Sometimes when replacing a windshield or repairing the blades themselves, the assembly is carried out incorrectly, after which a situation arises when the wipers do not return to their original position. Make sure the wipers are installed correctly in the slots, check the motor and trapezoid, it may be installed incorrectly

Pay attention to the crank of the windshield wiper transmission element; before disassembling one or another element, you must remember its location and do not confuse anything during assembly

The problem may lie in the unit (engine) itself or its switch, in these cases you will have to completely repair or replace the above items.

There can be many reasons why the wipers do not return to their place, from trivial to very complex, they are all quite difficult to predict and list, it all depends on the specific car model and the malfunction itself. If nothing works out for you, contact a specialist; the gas station will definitely help eliminate this unpleasant malfunction. This concludes our article on windshield wiper faults, until we meet again, stay safe.

Z.Y. If you know of any other reasons why the wipers do not return to their original position, you can share them through the comment form.

Windshield wiper repair

Since the system diagram is quite simple, repairing it at home will not be difficult. We will not describe the repair for a long time, since it can be performed without instructions, in particular, we are talking about replacing nozzles, hoses and a motor. In the case of a motor, when replacing it, you just need to disconnect the hose and remove it from the tank, replacing it with a new one. When installing a new pump, the contact surface with the tank should be treated with sealant to prevent the possibility of leakage.

We will dwell in detail on the repair of the trapezoid, since this part of the structure most often raises questions among owners of fours. As stated above, due to the inoperability of the trapezoid, the wiper blades will work slowly, so this element will need to be replaced. In principle, replacement is carried out in the event of mechanical damage to the device. In general, the replacement process is quite simple, but to perform the task correctly, you must follow the sequence of actions described below.

So, how to remove the trapezoid:

First, disconnect the wiring under the hood that connects to the unit.
Dismantle the protective casing behind which the heater fan is hidden. You will also need to remove the stove filter.
The stove motor must be disconnected from the on-board network; to do this, simply move it to the side. It is not necessary to remove this element.
Next, the cover is removed from the windshield wiper. Under the rubberized casing you can see the nut that secures the wiper. The casing itself should be lifted slightly - this way you can unscrew the nut without any problems, after which the windshield wiper can be removed.
After this, you need to remove the rings, as well as the sealing components, from the purifier shaft. The same must be done with the other wipers.
In the engine compartment you can see the bolts securing the trapezoid - they need to be unscrewed. At the final stage, it is necessary to dismantle the heater motor and unit or unscrew the trapezoid gearbox and then remove it.

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.

Next, we will consider these two stages in more detail.

Rear wiper removal process

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

First of all, use a flat screwdriver to lift the protective cover of the wiper arm mounting.
Using a “10” wrench, unscrew the fastening of the windshield wiper arm and remove the arm itself.
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.
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?

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

-windshield wiper gearbox

If upon inspection it turns out that the reason for the non-working wipers was the VAZ 2114 windshield wiper motor, then it should be replaced, which will require:

flat blade screwdriver;
a set of heads and handles (or a pair of keys for 10 and 13);
new gear motor.

The replacement itself in this case should be carried out in the following order:

Remove the ground (negative) terminal from the vehicle battery.

At this point, the process of disassembling the windshield wiper motor can be considered completely completed. Assembly and installation are carried out in the same order, but in reverse order.

When installing a new gearmotor, it is important to place the shaft in the correct starting position before connecting it to the crank. To do this, it is necessary to turn on the engine, not connected to the trapezoid, to the on-board network through a switch, switching the latter to intermittent mode. After stopping and stopping the crankshaft, it will be in its original position.

After completing the replacement of the wiper motor, you need to connect the negative terminal to the battery and check the operation of the wipers in all modes. If the problem persists (for example, the wipers move to their extreme position and stop), you should also check other components in the electrical circuit, such as control relays or keystone limit switches.

In conclusion, it is worth adding that in order to extend the service life of the wipers, it is necessary to periodically (for example, once a year) carry out their complete disassembly and inspection (for example, the presence of bending of the connecting rods or the appearance of the gaps in the moving joints). Such timely elimination of minor mechanical defects will reduce the load on the electric motor and, as a result, extend its service life.

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.

Windshield wiper motor - when repairs are required

Welcome, friends, to the DIY car repair website. Windshield wipers are an indispensable attribute of any car.

Whatever the car is - cheap or expensive, domestic or foreign, passenger or truck, it must have wipers.

The main thing is that they are in good working order and ready to work. In this case, the main element that is responsible for the motor function is the windshield wiper motor.

How does a windshield wiper motor work?

Most cars have two blades, which provide more effective cleaning of the windshield. A single wiper is usually mounted on the rear window.

The device operates in two or three modes, which allow the brushes to provide intermittent, slow or fast cleaning.

The overall design includes a wiper motor (a small motor with a gearbox), a brush return mechanism, a lever system and the cleaning rubber bands themselves. In parallel with the cleaner, you can use the windshield washer, which supplies water in the form of a directed jet.

One of the most unreliable elements of the system, which often fails, is the motor. If it breaks down, motorists do not know what to do and what the reasons may be.

Frameless wipers: features

This design does not have its own frame. Essentially, frameless wipers are a type of strip that has a steel plate inside it. Their appearance is in perfect harmony with any car, which cannot be said about the wiper frames.

These models do not belong to the economic segment. Such wipers are selected individually for different brands of cars. The curvature of the windshield of any car is determined by aerodynamic parameters. Therefore, the curvature of the wiper must also be appropriate.

That's why cheap wipers don't press well and the glass doesn't wash. It is impossible to repair such brushes. You just need to install new, better ones. Premium brushes will work perfectly regardless of the car model. However, they cost more than 1000 rubles.

A positive quality of frameless models is considered to be easier to clean the windshield wiper from ice in winter. Just fold them a couple of times and the ice will fall off instantly. These wipers have excellent aerodynamics. At high vehicle speeds, their downforce increases.

Motor malfunctions and solutions

Let's look at what to do if the windshield wiper motor does not work, and what can cause such problems. There are several options:

1. The electric motor does not work, the bimetallic fuse is inactive, and the fusible insert responsible for powering the wipers is intact. In this case, you need to check the serviceability of the wiring, the quality of connections of all contacts, determine any existing damage and eliminate them.

If everything is fine with the wiring, then you should check the wiper switch. If it acts up, just replace it. The engine itself may not work - this often happens when brushes stick or contact connections burn.

In this case, you need to repair the windshield wiper motor - inspect it, replace faulty elements, and clean dirty components. It is important to check the integrity of the wiring that connects the electric motor and the block.

The next step is to check the bimetallic fuse, which needs to be cleaned, and if repair is impossible, simply discarded and replaced with a new one. If this does not help, check the motor armature winding for integrity. If there is no chain, then it is necessary to replace the armature or the entire mechanism as a whole.

2. The bimetallic fuse works, the motor does not start, and the power fuse constantly blows. The first thing to do is check the integrity of the levers. Often they do not work due to deformation or freezing of the brushes to the windshield.

The worst thing is if the cause of such a problem is a short circuit in the armature circuit. Here, repairing the fault is possible in only two ways - by installing a new armature or replacing the gearbox.

3. Interrupt mode does not work. Here the problem is either the relay or the wiper switch. In the first and second cases, it is better to replace the faulty element.

4. The wipers do not stop in interrupt mode. The reason is a relay failure or a malfunction of the limit switches. In the latter case, the gear cam of the gearbox simply does not press the spring plate. The problem is solved by bending it a little.

Do the wipers turn on themselves on the VAZ 2114? Solution

Water and dirt accumulate on the windshield during rain, snow, and dust flows. To get rid of this, the design of the car provides for the presence of special elements - wipers.

Circuit breakers

Schematically, wipers look quite simple - brushes, consisting of a lever and a rubber gasket, move in a certain direction and thereby clean the surface. The wipers are driven by a special gear motor. This allows the devices to clean the front and rear windows of the car.

Inside the cabin, at the driver's fingertips, there is a windshield wiper speed control . Brushes can have different sizes and function in several modes.

If we talk about windshield wipers on the VAZ 2114, they have four operating modes:

With interruptions;
At first speed;
At second speed;
Together with washer.

There are two modes on the rear window:

With washer;
No washer.

It is noteworthy that for some reason there are significantly fewer situations when the rear wiper does not work on a VAZ 2114 than in the case of front windshield wipers. Most likely, this depends on the intensity of use of the front and rear wipers.

Why are my wipers slow?

Water and dirt accumulate on the windshield when it rains, snows or blows dust. To get rid of this, the design of the car provides for the presence of special elements - wipers.

Switches

Inside the cabin, at the driver’s fingertips, there is a wiper speed control. Brushes can be of different sizes and work in different modes.

If we talk about wipers on the VAZ 2114, they have four operating modes:

Interrupts
At first speed;
At second speed;
Along with the washing machine.

There are two modes on the rear window:

With a washer;
No washing machine.

Dimensions

After all, the size of the wipers on the VAZ 2114 plays a rather important role in the quality and efficiency of glass cleaning.

Wiper connection diagram

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

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

The windshield of the VAZ 2114 has two blades of the same size - 51 centimeters. The driver's side blade can be replaced with a 53 cm long element, but it is important to leave 51 cm on the passenger side, otherwise there will be a strip of clean water on the glass between the driver and passenger.
The rear window of the VAZ 2114 also has a cleaner. But in this case, the element size is 30 centimeters. The vacuum cleaner can be installed at a height of 33 centimeters, which allows it to perfectly adapt to the size of the rear window. Some even install components at 40 centimeters, but in this case you will have to increase the wiper travel limit. To do this, we remove the motor, move the teeth of different units and install it.

Car owners are often faced with a situation where the wipers on a VAZ 2114 do not work properly. The causes of problems may vary, so you need to carefully examine the problem and then take appropriate action.

Typical failures include:

They work constantly;
The wipers can work independently, although the driver has not turned on or pressed anything;
It may be too slow;
Spontaneous combustion occurs.

Replacing the motor

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

There are several reasons:

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

To avoid breaking the teeth of the new gearmotor due to the crank (the curved rod connecting the motor and the trapezoidal arms), proceed as follows:

Disconnect the fuse.
Mark the position of the handle.
Disconnect the connecting rod mounts.
Unscrew the trapezoid mounting bolts.
We remove the engine.

Trapezoid repair

If the wipers on a VAZ 2114 work slowly, this indicates the need to repair the trapezoid. Although this cannot actually be fixed, it is enough to replace the failed element.

Replacing the trapezoid

Replacement will be required in case of mechanical damage. The procedure is quite simple, but here you must follow a certain sequence.

Disconnect the wires under the hood that connect to the fuse box.
Remove the heater fan protective cover.
Remove the heater (stove) filter.
Turn off the stove motor. It just slides to the side, no need to disassemble it.
The cover is removed from the windshield wiper.
Under the rubber boot there is a nut that holds the wiper in place. The lid should be slightly raised and the nut will be easy to unscrew. Remove the windshield wiper.
Remove the rings and spacers from the wiper shaft.
Do a similar procedure with the second wiper.
Under the hood, unscrew the bolts connecting the trapezoid to the body.
We remove the fuse box and the stove motor, or unscrew the gear motor from the trapezoid, after which the motor and trapezoid are removed one by one. There are two ways to get a broken trapezius.

Washing system diagram

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

The steering column switch does not work. Verify this by shorting the two terminals under the steering wheel - front terminal 53ah-w, rear terminal 53ah-wh, then measure the resistance. If it is low, the switch is replaced with a new one.
Water does not flow through the washer pump. It should also be replaced.
Dirt has formed in the injectors. Use a sharp needle to clean them.
Broken wire connecting the pump and the switch. You yourself understand that the only option is replacement.
Faulty relay K3. Again, you have no choice but to change the relay.
The tube burst, its integrity was damaged. What do you think should be done in such a situation? Right: change handset.

If it so happens that you had to replace the standard wipers on a VAZ 2114 with new ones, give preference to modern wipers.

No frame

Their advantages are obvious:

High reliability indicators compared to outdated projects;
Long duration;
There is no creaking during operation;
Perform your task efficiently: glass cleaning.

Frameless wipers are by no means a cheap pleasure and they need to be selected individually for a specific car model. Price tags start from 1000 rubles, and these are far from the best representatives of the premium brush segment.

But frameless devices perform well in winter, ideally clear snow and icing from the windshield, have excellent aerodynamics and increase downforce when driving at high speed.

Windshield wipers are an important element of any car, the failure of which can affect not only comfort, but also traffic safety. A poor view of the road from the driver's side leads to dire consequences, so make sure that the wipers always work properly.

I welcome you, friends, to the do-it-yourself car service website. Windshield wipers are an indispensable attribute of any car.

The main thing is that they are in good condition and ready to work. In this case, the main element responsible for engine operation is the wiper motor.

Most cars are equipped with two blades, which provide a more effective cleaning of the windshield. The rear window is usually equipped with only one wiper.

The device operates in two or three modes that allow the brushes to provide intermittent, slow or fast cleaning.

One of the most unreliable elements of the system, which often fails, is the engine. In the event of a breakdown, motorists do not know what to do and what the reasons may be.

1. The electric motor does not work, the bimetallic fuse does not work, and the fuse insert responsible for powering the wipers is working. In this case, it is necessary to check the functionality of the wiring, the quality of connections of all contacts, determine any existing damage and eliminate them.

If everything is fine with the wiring, you should check the wiper switch. If it disappears, replace it. The motor itself may fail - this often happens when brushes stick together or contact connections burn out.

Trapezoid repair
Problems with the washing machine
Modern wipers

Water and dirt accumulate on the windshield when it rains, snows or blows dust. To get rid of this, the design of the car provides for the presence of special elements - wipers.

Switches

Schematically, wipers look quite simple: brushes, consisting of a lever and a rubber gasket, move in a certain direction and thereby clean the surface. The wipers are driven by a special gear motor. This allows the devices to clean the front and rear windows of the car.

If we talk about wipers on the VAZ 2114, they have four operating modes:

Interrupts
At first speed;
At second speed;
Along with the washing machine.

There are two modes on the rear window:

With a washer;
No washing machine.

It’s remarkable, but for some reason on the VAZ 2114 there are fewer situations when the rear wiper does not work than in the case of the front wipers. Most likely, it depends on the intensity of use of the front and rear wipers.

Dimensions

After all, the size of the wipers on the VAZ 2114 plays a rather important role in the quality and efficiency of glass cleaning.

If the standard length of the brushes is exceeded, the force of pressure of the brush on the glass decreases, which reduces the effectiveness of cleaning the surface. Additionally, a device that is too large may begin to touch elements that no longer belong on the windshield. For example, the edges of doors.

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

The windshield of the VAZ 2114 has two blades of the same size - 51 centimeters. The driver's side blade can be replaced with a 53 cm long element, but it is important to leave 51 cm on the passenger side, otherwise there will be a strip of clean water on the glass between the driver and passenger.
The rear window of the VAZ 2114 also has a cleaner. But in this case, the element size is 30 centimeters. The vacuum cleaner can be installed at a height of 33 centimeters, which allows it to perfectly adapt to the size of the rear window. Some even install components at 40 centimeters, but in this case you will have to increase the wiper travel limit. To do this, we remove the motor, move the teeth of different units and install it.

Disconnect the negative battery terminal
Turn both windshield wiper arms to a vertical position and unscrew their fastening nuts.
Removing the wiper arms from the wiper rollers

The nuts securing the brush arms are unscrewed, after which they can be removed from the conical grooves of the drive. If this is difficult, a penetrating lubricant can be applied to the grooves.
The brush lever drives are disassembled by unscrewing the lock nuts, then the plastic bushings and rubber seals are removed.
The terminal block in the harness is disconnected and removed by lifting the tab of the gasket through a slot in the engine compartment bulkhead.
The next step is to directly remove the wiper. Then the washer and spring clip are unscrewed from it, and the thrust is turned off.
By unscrewing the three mounting bolts, you can remove the motor.

The fuse responsible for the operation of the windshield wiper motor has blown. In this case, it is necessary to check its integrity in the fuse box and, if necessary, replace the blown one with a new one.
Poor connection of the power plug of the wiper motor itself. Try disconnecting and reconnecting the microcircuit, and also inspect the contacts inside them.
Windshield wiper motor malfunction. It happens very rarely, since the design is quite reliable. But if such a problem occurs, it will be necessary to replace the burnt part.
The wiper control mechanism on the VAZ 2114, or rather the trapezoid, has broken down. Carefully inspect the trapezoid and check to see if one of the rods is loose. If a malfunction is detected, you should fix it yourself or replace this design.
Trapezoid jam. A similar malfunction can often be observed when the keystone bushings become sour and the wipers begin to jam. Disassembling and lubricating the structure will help solve this problem.
The windshield wiper switch is faulty. The solution is to replace the steering column switch.

adapter;
lever system (trapezoid).

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

If the standard length of the brushes is exceeded, the force of pressing the brush against the glass decreases, which reduces the efficiency of cleaning the surface. Plus, a device that is too large may begin to touch elements that no longer belong on the windshield. For example, the edges of a door.

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.

Modern wipers on the VAZ 2114

To clean the VAZ 2114 windshield from dirt and soot in the rain, a special device is provided, the so-called VAZ 2114 wipers. When replacing the windshield wiper motor, the blades move back and forth.

The result is a clean windshield or rear window. There is a wiper speed control inside the car. He is almost always driving. The size of the brushes can be very different. Most wipers operate in different modes. The windshield wiper operates on 4:

pause breaks;
1st speed;
2nd speed;
work with a washing machine.

The rear window has two modes:

Functionality and quality of modern windshield wipers

It must be said that the quality of windshield wiper blades and their size have a huge impact on the safety of the car. Therefore, choosing the right wiper remains a very important task. The reliability and quality of cleaning products is determined by the fact that:

calm down;
have a long service life;
ideal for cleaning windows.

If at least one of the properties described above is absent, there is no comfort in the car, and there is a risk of getting into an accident due to limited visibility, especially in the event of rain. The size of the windshield wiper blades plays an important role. If this is a little more than necessary, the force of the brush on the glass, especially when working with a frameless wiper, is significantly reduced. As a result, the glass does not clean very well.

Also, the large size of the brush will affect the cleaning of the floor. The windshield wiper may touch the rubber of the windshield with its edge, so it does not touch the working surface. On Kalina's car, a large hand begins to touch the edge of the driver's door. When the brush size is much smaller than required, a decrease in the cleaning area is observed. The windshield does not clean one hundred percent.

At the same time, small wipers leave a dirty island on the glass. What size should the brushes be on a VAZ 2114? This car model is equipped with 2 windshield wiper blades. They have the same symmetrical size of 51 cm, but the brushes can be installed with slight scaling.

The brush can be 53 cm long on the driver's side and 51 cm on the passenger side. When installing similar brushes 53 cm long, a small strip of water is formed in the center of the glass. The rear window of the car is also equipped with a windshield wiper.

Common problems

It is not uncommon for car owners to encounter a situation where the wipers on a VAZ 2114 do not work properly. The causes of the problems may be different, so you should carefully examine the breakdown, and then take appropriate action.

Typical faults include:

They work constantly;
The windshield wipers may operate on their own, even though the driver has not turned anything on or pressed anything;
May work too slowly;
Spontaneous switching occurs.

Mechanical contamination and damage

Freezing. Often problems with wipers begin during the off-season period, when there are frosts at night, and in the morning the air warms up to above-zero temperatures. You turn on the windshield wipers, not noticing that they are frozen to the glass. It seems like nothing is happening, but if you repeat this abuse of the motor regularly, the gears will fail and the motor will break.
Foreign objects. A falling stone or branch can damage the moving part of the mechanism because it creates resistance that the motor mechanism is not designed to withstand. If they then fall out while driving, you will not be able to understand why the wipers on the VAZ 2114 do not work well and what happened.
Damage to wires. The winding of old wires becomes brittle and can easily break. In this case, voltage losses in this area and a drop in the speed of the wipers are inevitable.

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.

All this suggests that the motor needs to be changed. In fact, this is the simplest three-speed electric motor. Its design includes a fuse. It can be located on the body or hidden inside the unit. Replacing the element is not difficult; you just need to remove the four bolts responsible for fastening it.

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:

Turn off the safety block.
Mark the crank position.
Disconnect the crank fasteners.
Unscrew the trapezoid fixing bolts.
Remove the motor.

Windshield wiper installation process

Replacing VAZ wipers is carried out in the following sequence:

Open the hood of the car.
Check battery disconnection.
Insert the new assembly into the hole. Connect the plastic fastener to the wires.

Installing a new node

Tighten the lower bracket of the mechanism with a bolt.

Bottom mounting bolt

Connect the wiring harness to the block.

Connect the wiring harness to the block

Close the hood.
Place a rubber gasket on the upper mount of the purifier bracket and tighten it with a nut.

We put on the rubber gasket and tighten the nut

Cover the nut with a protective cap.

We put on the protective cap

Install the lever on the motor.

Installing the windshield wiper arm

Securely tighten all purifier mounting nuts.

After installing the wipers, turn them on and check for squeaking and the degree of cleaning of the glass surface.

The size of the product plays an important role when operating a car. If you install a part that is larger than the original, then the force of pressing the brush on the glass will not be sufficient to cope with the contamination. The edge of the brush will begin to cling to the rubber seal, resulting in poorly cleaned glass.

Trapezoid repair

If the wipers on a VAZ 2114 work slowly, this indicates the need to repair the trapezoid. Although in reality it cannot be repaired, you just need to replace the failed element.

Replacing the trapezoid

Replacement will be required in case of mechanical damage. The procedure is quite simple, but here you will have to follow a certain sequence.

Disconnect the wires under the hood that connect to the fuse box.
Remove the protective cover that covers the heater fan.
Remove the heater (stove) filter.
Turn off the heater motor. It simply slides to the side; there is no need to dismantle it.
The cover is removed from the wiper.
Under the rubber protection cover there is a nut that holds the windshield wiper. You need to lift the cover a little and the nut will be easy to unscrew. Remove the wiper.
Remove the rings and gaskets from the wiper shaft.
Carry out a similar procedure with the second wiper.
Under the hood, remove the bolts that connect the trapezoid to the body.
Remove the fuse box and the stove motor, or unscrew the gear motor from the trapezoid, after which the motor and trapezoid are removed one by one. These are two ways that will allow you to get a failed trapezoid.

Modern wipers

If it so happened that you had to replace the stock wipers with new ones on your VAZ 2114, give preference to modern windshield wipers.

Their advantages are obvious:

High reliability indicators compared to outdated designs;
Long service life;
No squeaks during operation;
Effectively perform your task - cleaning glass.

Particular attention should be paid to the new frameless windshield wipers. Their design does not provide for the presence of a skeleton. Basically, it's a kind of tape with a steel plate inside

Externally, they perfectly match the design of the VAZ 2114, which is seriously ahead of their frame counterparts

Essentially, it is a kind of tape with a steel plate inside. Externally, they perfectly match the design of the VAZ 2114, which is seriously ahead of their frame counterparts.

Windshield wipers are an important element of every car, violation of the functionality of which can affect not only comfort, but also traffic safety. Poor driver visibility of the road leads to dire consequences, so make sure your windshield wipers always work properly.

Washer problems

For optimal and efficient operation of windshield wipers, they require a constant supply of water. To automate this process, engineers have developed a device called a washer.

Replacing the windshield wiper trapezoid on a VAZ 2108, VAZ 2109, VAZ 21099

Hospitality! In today's article you will learn how to replace and repair a windshield wiper blade. You will also learn how to completely disassemble and reassemble the windshield wiper trapezoid. The replacement of the trapezoid will be carried out on cars, as evidenced by the name of the family record “Samara.

Note! In addition to repairing the windshield wiper trapezoid, the article also includes repairing a motorcycle gearbox, which is also a very important and fundamental element in the work of wipers!

When is it necessary to replace the trapezoid with a new one? In some cases it needs to be replaced if it breaks, and in some cases it may not need to be replaced with a new one at all, you just need to remove it and then fix it.

When a trapezoid breaks, as a rule, the car's wipers begin to work incorrectly, namely:

They may be slow for no apparent reason.
Or it doesn't work at all.
