Why the wipers work slowly on the VAZ 2114

Are you faced with the fact that your VAZ-2109 wipers are working slowly? It doesn’t matter, this problem haunts many motorists. A careless mechanism, which only yesterday worked like a clock, has a stupid habit of slowly and inexorably breaking down. This unpleasant feature of cars of this brand has already managed to annoy all owners of the VAZ model 2109, if you believe the reviews of the majority of domestic motorists.

There can be a huge number of reasons for this, and it is not always due to driver negligence. Windshield wipers often fail due to banal technical imperfections in the design of everyone's favorite VAZ. But you shouldn’t scold the manufacturers prematurely and go to a car service center. Speeding up a worn-out mechanism with your own hands is simple and anyone can do it.

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:

Damage to system levers. Even a slight change in the shape of these parts can affect the speed of the mechanism.
Faulty power cords. If there is not enough electricity supplied to the system, it is no wonder that it will slow down.
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.
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.
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.

Frame Wiper Blades

Frame wiper blades are a skeleton to which a cleaning rubber band is attached. In other words, rocker arms extend from the wiper arm (there are 2, 3, 4 of them depending on the model), to which a cleaning tape is attached, despite the fact that the tape is in free circulation (it can move forward and backward). Each wiper arm is movable and, thanks to this, is able to fit tightly to the glass.

Due to their design, the windshield wiper blades do not need to be replaced entirely, but can only be done by replacing the cleaning tape. This is definitely a plus, because... the cost of the tape from a set of new wipers is noticeably different in favor of the former.

True problems and ways to solve them

The mechanism’s motor and the windshield wiper trapezoid itself are the main pitfalls of this malfunction. Once you forget about them for just a couple of months, the wipers begin to slow down, gradually becoming unusable. Unfortunately, there is no easy way to find out about this problem. You can learn how to properly and promptly care for a car only by facing all its shortcomings face to face or by asking your friends, at worst.

The thing is that without timely cleaning and lubrication, both parts quickly wear out and eventually refuse to work. Trapezium malfunctions lead in frequency of occurrence. Either the hinges begin to jam, or the strips bend for unknown reasons. However, the motor is also not far behind. Coupled with the loss of voltage due to damage to the wires, the part causes many problems, sometimes forcing an inattentive driver to buy a new one if he does not check the serviceability of the electrical wiring.

So what can you do to return your wipers to their former speed?

The answer is simple: disassemble the mechanism, clean and sand the motor with sandpaper, lubricate the hinges located between the trapezoid bars - that’s all.

Unfortunately, if this does not help, and you have not found any other faults, only replacing parts or a trip to the service center can help you. However, replacing the notorious trapezoid or motor solves the problem in most cases.

Quick diagnosis by weight

The ground outlet is located on the lower bolt of the windshield wiper drive, in the sump. If you suspect that the problem is a bad ground, turn the windshield wipers on maximum and note the speed of their movement. Then turn on the stove. The heater and wipers are connected to the same ground output, so if this is the problem, the speed of movement of the wipers after turning on the heater will decrease significantly.

To fix the problem, find the ground outlet, clean the contacts, solder the terminals if necessary, coat the connection with protective grease, and tighten the fastening nut well.

If you need to quickly eliminate voltage losses, extend an additional ground wire to the wiper motor mounting frame.

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.

How to speed up wipers in intermittent mode?

If you are wondering how to make wipers faster on a VAZ 2114, then you should turn to the features of the wipers. This car has 3 wiper modes, namely intermittent, fast and normal.

Intermittent and normal modes imply movement of the brushes at the same speed, which is slightly less than in fast mode. You can set the speed in intermittent mode to be maximum, but in this case it will decrease in fast mode. In fact, to do this you need to swap the wires in the connector to which the wipers are connected. In order to determine which wires to change, it is worth looking at the diagrams.

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.

Wiper gear motor

When operating a car on rural roads, and not only that, the problem arises that the electric motor of the mechanism becomes clogged with dust and dirt.

Of course, in such cases there is no doubt that normal operation of the wiper motor is out of the question. In this case, you need to clean the mechanisms from dust and dirt, rinse them, apply new lubricant and put everything back in place. When connecting the motor back, check the plugs for contamination; they may also oxidize and change color. In this case, it is better to unpin the plug and thoroughly clean each of the contacts and the housing itself.

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.

Fast wipers on the VAZ 2114: modernization and causes of breakdowns

If you are faced with the fact that your wipers on your VAZ 2114 are working slowly, do not worry. Many motorists have to deal with this problem; the problem lies in the mechanism used; it often fails. This is evidenced by numerous reviews from the owners of this model, and the reasons for the breakdown can be very diverse. Often products stop working due to imperfect design. Be sure that you will be able to modify the wipers of the VAZ 2114.

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.

I think many owners of VAZ 2108-09, 2114-15
are familiar with the problem of sluggish, dying wipers, I am no exception. There have been cases where the wipers stood in the middle of the glass and did not move. This happened once when I was driving from another city at night in winter, I had to drive 100 km with non-working wipers. It was very uncomfortable and dark. I was about to change the wiper motor when I learned about this simple method that will give our old motor a second life.

And so the point is that we need to make some kind of wiring harness with a relay that connects the wiper motor block and the block from the CY and power our motor directly from the battery, thereby we will allow it to receive power without any losses.

What you will need:

● Connector 6.3mm 6-terminal mother and father -
75
rubles ● Relay 5-pin -
55
rubles ● Relay connector block with 5 wires -
40
rubles ● Fuse holder -
30
rubles ● Fuse 10A -
3
rubles ● Wire ( 1m was enough for me) -
10
rubles ● Ring terminal -
3
rubles

Here you will have to suffer to understand which wires to connect where.

In the end we get such a wiring harness.

Just in case, I installed a 10A preamp on the power cable.

I covered it all with a 5 liter canister to prevent moisture from getting into the chips.

You should also adjust the crank on the motor if, after modification, the wipers park higher.

Results!

They are impressive! The wipers have 3 operating modes, as expected, the first is fast and intermittent, the second is as fast as possible and without a pause, and the third mode, which is no different from the second, but this is a trifle because I personally don’t need the third mode with such fast wipers, and neither do you I think so too.

Before modification The engine is switched off, the wipers are operating in the first mode.

2nd mode from the street with the engine running

All modes from the cabin

In general, I recommend it to anyone who has problems with wipers! This is probably one of the most useful improvements, now you can drive without fear that the wipers will not cope and will get stuck.

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.

Washer system diagram

Breakdowns and ways to fix them are different. Let's get to know them in more detail.

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.
There is no water flowing through the washer pump. It should also be replaced.
Dirt has formed in the injectors. Use a sharp needle to clean them.
The wire that connects the pump and the switch has broken. You understand that the only option is replacement.
Relay K3 is faulty. Again, you have no choice but to change the relay.
The hose ruptured and its integrity was compromised. What do you think should be done in such a situation? Absolutely right - change the hose.

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.

Frameless

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. 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.

Frameless wipers are not a cheap pleasure and you need to choose them 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 excellently in winter, they perfectly clear snow and ice from the windshield, have excellent aerodynamics and increase downforce when driving at high speeds.

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.

The entire windshield cleaning system has a very long service life. But there are often cases when some mechanism fails and, as a rule, this happens through the fault of the car owner himself. But this problem does not arise due to the human factor, but does not exclude it.

This problem most often appears in winter or spring. It appears due to metal oxidation and lack of lubrication.

If you are faced with this problem, we recommend that you remove the entire trapezoid completely, lubricate all the bushings (where the leads are attached), hinges, axles of the leads and other rubbing elements with lithol.

To lubricate the axle, you need to remove the leads, remove the retaining rings, remove the washers, push the axles under the hood and lubricate them.

We recommend that you completely dismantle the entire trapezoid, because... The hinges get clogged with dirt and rust, and it is almost impossible to clean them without dismantling them.

Wear of the gear motor. In this case, it is recommended to disassemble the gear motor and clean out all dirt. Sand between the petals of the gearbox with fine sandpaper, sand the brushes, lubricate with lithol, and assemble.
Consequences of incorrect installation. If, before this problem, you were replacing trapezoid rods and so on, then most likely you installed something incorrectly.
