VAZ 2114: wipers work slowly

The windshield wiper mechanism on any car is an important element when moving, and if there are any problems with it, you should immediately begin repairs. Problems often arise both in the electrical and mechanical parts. The first signal in the event of a problem will be slow operation, but why do the wipers on the VAZ 2114 work slowly? If you do not approach this moment in time, then at the most inopportune moment there is a chance to remain almost “blind” on the road in bad weather.

Trapezoid wipers

One of the common reasons for the slow operation of wipers on a VAZ 2114 is a rusted trapezoid. The problem with it can most often arise in winter or spring, due to low temperatures outside.

For ease of operation, remove the mechanism and disconnect the rods. We clean all connections from rust and old grease. Before assembly, each connection is generously coated and installed in place. It is recommended to periodically lubricate the joints even after repairs. This can be done without removing the mechanism; just remove the anthers and gain access to the connections.

Let's sum it up

If reliable operation of the windshield wiper is your priority, you should pay attention to all possible ways that parts may fail. The knocking trapeze should attract your attention and in a certain way force you to examine the situation. Most likely, the knocking will lead to the fact that you will soon have to replace the device with a new one and buy high-quality replacement parts. But it is quite possible that you just need to get to the trapezoid and tighten the fastenings of its parts in order to eliminate the knocking and continue to operate the device perfectly.

High-quality work of wipers is necessary in any car, so you should immediately solve all problems that arise, taking into account their features and technical difficulties. Replacing the relay can be done in a garage, but it is better to change the trapezoid and wiper motor in a service center. This way, you can get the necessary capabilities for operating the machine without any problems and acquire the necessary performance qualities of peripheral devices. Have you ever encountered problems with your wipers?

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.

What to do if the wipers on the VAZ 2109 are slow or faulty

If the car's windshield wipers no longer perform their functional tasks correctly, then certain repair work will be required. To do this, you need to arm yourself with a standard set of tools.

To begin work on identifying faulty parts of the mechanism, you need to completely disassemble

.
After this, it is recommended to follow this procedure
:

Check the condition of the electric motor structure, its windings and the armature shaft. You should carefully inspect all parts for any damage or deformation. If large scratches or damage are found on the surface that cannot be sanded, then it is better to replace such parts with new ones.
Determine the condition of the brushes and their springs. If damage or loss of elasticity of the mechanisms is detected, they must also be replaced.
Check how freely the brushes move in the special holders. The fact that they are difficult to move may cause the VAZ 2109 wipers to work slowly
. If there is any binding, you can try to correct it with sandpaper. If there are cracks, chips or high levels of wear, it is better to replace the brushes. You may need a soldering tool to replace them.
Inspect the condition of the collector. If there are traces of carbon deposits on the surface of the device that arise from friction with the brushes, you can try to eliminate this fact with a special polishing paste. There should be no damage to the commutator in the form of scratches or burrs. If such are present, then you need to treat these places with sandpaper. When these methods do not help get rid of defects, it is necessary to replace the part.
Inspect the design of the gearbox drive. Its gear should not have chipped teeth or any other defects. If there are any, it is better to install a new gear.
Check the wiper drive rods. They should not be bent under any circumstances. If there are minor deformations, you should try to correct them using certain available means.
Determine the condition of the threaded elements of the lever shafts in the wiper mechanism. If the threads are damaged, the rods must be completely replaced.

Bad mass

The next common cause is a poor electrical system. The mass fastening is located on the lower bolt of the mechanism drive. There is a simple diagnostic method in this case:

Turn on the wipers to maximum operating mode and remember their speed.
Turn on the car's heater.
If it is noticeable that the speed has decreased significantly, then the problem has been identified.

This happens because the mass of the stove and wipers are secured to one bolt. To fix the problem, it is enough to clean the contact area of the terminal and the body from rust; it is also worth assessing the wire, there may be a problem with it.

TOP 10 cool products for Lada Niva 4x4 from China from Aliexpress. Tuning VAZ Niva

Hello friends! Today I will present to your attention 10 useful products from China from the Aliexpress website for a real men's car Lada 4x4 Niva.

LED optics

LED headlight assembly. In addition to low and high beams, these headlights have DRLs (daytime running lights) on board in the form of angel eyes and simple backlighting, depending on the modification.

These headlights have a power of 75 watts, a color temperature of 6000 Kelvin and a luminous flux of 6000 lumens. LED chips are used from the world leader in the LED industry, CREE.

Voltage leakage due to damaged wiring

Problems may also arise in the electric motor connection circuit itself. To determine why the wipers are moving slowly, we will need a voltmeter. We measure the drop on ground and the positive wire in different operating modes of the wipers, then record the drop on each contact. In some cases, drops can reach up to 0.8 V. If higher, it is worth looking at all the wiring to the mechanism or replacing it.

Design reasons for slow rotation of courtyards

VAZs are primarily distinguished by their poor factory preparation. At specialized auto forums, they are actively discussing an alternative electrical control scheme for a geared motor, intended for use on both the VAZ 2109 and the “ten” with Priora.

It cannot be said that three relays connected in a certain sequence have a noticeable effect on all machines. Most likely, the implementation lets us down. This system does not tolerate “twisted” wires, which are known to have large losses of electric current. Another thing is soldering or male-female terminals.

Freezing

Often in winter, on a cold car, you can encounter the effect that the wipers work slowly or hardly move. In this case, it is worth checking whether the wiper blades are frozen to the windshield. If everything is in order here, then the problem is in the trapezoid.

The trapezoid joints freeze to each other either due to a large amount of dirt on them, or if there is not enough lubricant. To correct a similar problem, use the material written earlier and carry out a similar procedure.

Electromechanical problems

An electric motor that shows no signs of life, no click and a blown fuse F5 - all these problems indicate faults in the gearmotor, which can be eliminated by replacing one of the components:

dirty collector in the electric motor rotor;
brushes that ensure continuous contact in the motor;
burnt collector;
broken armature winding.

There are other options: the electric motor does not want to work, but there is a click, or the fuse blows. In this case, you need to return the left lever to its base position as quickly as possible, since these problems indicate a short circuit in the electric motor. It needs to be completely changed.

With the same problems, there may be minor faults: brushes frozen to the glass, or wipers touching body parts. Under such circumstances, you need to carefully separate the brushes or straighten their mounting arms.

Presence of foreign objects

The problem of stones or twigs caught in the trapezoid is not common. They create resistance that the wiper motor is not designed to withstand. Because of this, the mechanism may stop working. The malfunction will probably go away on its own at the first bump, and you won’t even understand what the reason was. But the problem cannot always be solved so simply, therefore, following the example given above, we remove the anthers and inspect the mechanism. Do not try to leave the wipers on if something is preventing them from working properly. You may overheat the motor or relay!

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.

Wiper relay

This problem does not occur very often, but it is still worth considering. If you use a standard component, then if the mechanism is used intensively, it may not withstand the load and fail after some time. In this case, it is better to install a relay with delay adjustment in the fuse box, which will help reduce the load. The relay in the mounting block is located at the top and third on the left; you can also recognize it by special markings in the form of a windshield and wiper.

Even experienced mechanics will not be able to immediately tell why the wipers on a VAZ 2114 are working slowly; everything in this system needs to be inspected, taking into account the quality of spare parts for this brand of car. Approach the repair responsibly so that the car does not let you down in the future in the most inopportune situation.
