VAZ 2114: windshield washer does not work

During the operation of the car, a problem may arise that the windshield washer on the VAZ 2114 does not work. This happens because the system is often underestimated and not maintained. Mostly, breakdowns occur due to contamination inside the washer fluid barrel. The tubes and pump have a small capacity, because of this, even fine sand can cause big problems in the future. Try to fill with the cleanest possible water, or better yet, use a special liquid that is sold at any auto store. But what to do if there is already a fault? Let's look at the reasons for the VAZ 2114 windshield washer not working.

Simple mechanical failures

When a problem arises with washer fluid not spraying onto the glass, it is often due to simple problems:

The washer fluid barrel has run out. If you notice that the water is being used too quickly, check the body of the barrel, it may have developed a defect and is leaking.
The pipeline leading from the barrel to the injectors is clogged. This can easily happen if dirt gets into the barrel or bad water is poured into it.
The windshield wiper nozzles are clogged. This happens for the same reasons as in the previous paragraph.
The water used instead of washer fluid has frozen. This happens when the temperature outside drops.
The hose came off the pump. The hoses are usually not secured in any way and over time, due to wear, they may not fit tightly.
The hose leading to the injectors is pinched. A common occurrence at the junction of the hood. Check if the washer works when it is open.
Hose rupture. This usually happens due to the age of the product, the rubber dries out and loses its strength.

All of the above breakdowns can be easily detected and repaired yourself. If the liquid runs out, it needs to be added. If the water freezes, leave the car in a warm room, then replace the fluid with a more suitable one. Also, during operation, the hose burst or became pinched - replace it or lay it differently. But it may be that you have checked everything, but the problem still remains, which means the problem is in the electrical part of the mechanism.

Tuning wipers on a VAZ-2107 car

Quite often, a part such as a windshield wiper trapezoid fails, which cannot be repaired and may require frequent replacement. A small improvement will help you solve the problem - installing a frameless device instead of a standard wiper, which has a number of advantages:

spectacular appearance, the ability to make fundamental changes to the design of your car;
the absence of any hinge joints, due to which dirt, snow and excess moisture often accumulate on the body of standard wipers, leading to the most negative consequences;
much better adhesion to glass, which improves the quality of its cleaning.

Both repair and replacement of wipers can be done yourself if you have the appropriate experience, as well as a tool that allows you to dismantle certain components of the windshield wiper.

The fuse has failed

The simplest thing that could happen in an electrical situation is a fuse failure. But this simply couldn’t happen on its own. Check the contacts on the windshield washer motor and the wire itself for integrity. If everything is ok, replace fuse F7 with a new one. This fuse is also responsible for the cigarette lighter, so if it stops working at the same time as the washer, then the problem is definitely in fuses F7 .

It is possible that after replacement, the fuse will begin to fail again when turned on. In this case, you should look for the problem further. It is quite possible that the pump or steering column switch is shorting inside its housing.

Removing the windshield wiper motor

To repair the windshield wiper motor, it must be removed. To perform this operation, you will need a 10 and 22 open-end or socket wrench. All actions are performed in the following algorithm:

unscrew the wiper fastening nuts using a 10mm wrench;
windshield wipers are dismantled;
unscrew the fastenings of the wiper brackets with a 22mm wrench and remove the plastic inserts;
rubber seals are removed from the engine compartment;
the power terminals are disconnected;
wires are removed from the holes in the body;
the casing on the motor unfolds;
unscrew the fastening nuts using a 10mm wrench;
the gearbox is removed together with the brackets;
the trapezoid fastening nuts are unscrewed;
The windshield wiper motor is removed.

Upon completion of the windshield wiper repair, all procedures are performed in reverse order.

Problems with wired

The next issue to check is the system wiring. If you look at the VAZ 2114 windshield washer circuit, it is quite simple.

When checking the wiring, take this seriously, even if the fuse has not blown at the moment, there is still the option of shorting and melting the wire. When troubleshooting, it is best to replace the wiring with a new one, rather than wrap it with electrical tape. This will help increase the working life in the future.

Windshield wipers do not operate in intermittent mode

If a situation arises in which the wipers do not function in interrupt mode, then the breakdown should be looked for in the wiper relay. The cyclic operation of the products is ensured by closing and opening the contactor of the control relay. To check, we try to supply power to the relay block. In practice it looks like this:

the relay is removed;
use the switch located near the steering wheel to turn on the wiper switch;
Using a tester, you need to check whether there is voltage at the terminal.

If there is no power, the switch needs to be replaced. The reason may be a break in the control circuit, so it is necessary to find and eliminate this defect. If there is power, but the relay does not operate, then it needs to be replaced. The relay cannot be repaired, so it only needs to be replaced.

Pump fault

During operation of the vehicle, the VAZ 2114 windshield washer motor may also fail. If you do not hear the sound of the pump when you turn on the windshield washer, this is a sign of its malfunction. In this case, it is worth removing it and checking it. To check, connect the plus and minus from the battery directly to its contacts. If it works, then the problem is not with him. If there is no reaction, it should be replaced with a new one.

The wipers do not reach the extreme point

Often, owners of domestically produced cars are faced with a problem when, when turning off the wipers, the blades stop at the point where they were, that is, they do not return to the lowest position. The problem with such incorrect stopping of the brushes is directly in the drive gearbox. The gearbox is equipped with a limit switch, which is activated by a cam. The cam is designed to control the position of the brushes after the power to the switch lever disappears.

A breakdown occurs mainly when the driver turns on the windshield wipers that are frozen to the glass. As a result, the gearbox fails and must be replaced with a new one.

Faulty steering column switch

The last reason for the windshield washer not working may be the steering column switch, which controls the wiper system as a whole. To get to it you need to remove the plastic from the steering column by unscrewing several bolts.

To check it, you need to directly connect contacts 53ah to W or 53ah to 53H. If the mechanism starts to work, then the switch is faulty. We release it from the clamps and remove it, then install a new one and check its functionality.

For all the reasons listed above, the rear windshield wiper may fail. The rear injector has its own separate pump, installed next to the front one, and its own line. Typically, the tubes are laid along the roof of the car under the ceiling from the passenger compartment, and the nozzle is mounted on the top of the trunk lid. All problems associated with windshield washer systems can be resolved independently. The system is very simple, especially on VAZ cars. If you are faced with the question “why the windshield washer on the VAZ 2114 does not work,” then do not worry, repairs will not cost you very much and almost all problems can be solved on your own without coming to the service center.

The wipers stopped turning on

If the wipers on a VAZ-2107 do not work in two switch positions, then the reason is most likely hidden in a blown fuse. This element is located on the fuse block and serves to protect the circuit from overloads and short circuits.

Checking the fuse is the first thing you need to start repairing. To check, you should use a tester, or simply exchange it for a known good one of the same rating. In rare cases, fuse contacts may oxidize and need to be cleaned and replaced.

RULES OF OPERATION IN WINTER AND SUMMER PERIODS

Correct operation of the VAZ 2114 windshield washer involves filling in various cleaning fluids, as they say: “according to the season.” In the warm season, when the air is especially filled with gasoline fumes, soot and dust, it is better to fill the tank with glass detergent or plain water to which a cleaner additive is added (sold in car stores).

In winter, when the air temperature drops below zero, you can’t get by with plain water - it can freeze and break the plastic container. Here it is necessary to add an antifreeze additive, which increases the thermal stability of the washing liquids used.

Causes of washer malfunction

If the windshield washer does not work, it will not be difficult for an experienced driver to identify the cause of such a malfunction, and even a beginner, after familiarizing himself with the main failures in the cleaning system, will be able to eliminate them on his own.

Mechanical problems

The most important reason, as mentioned above, may be the lack of washer fluid; in this case, you just need to top it up. If it is present, but does not splash in the winter, then perhaps it is simply frozen. In this case, the problem can be solved in one of two ways:

warming up the engine;
bringing the car into a warm garage.

After the liquid has thawed, the system will begin to operate as usual, but it is better to drain the water from the tank after this and replace it with an “anti-freeze” one.

Other significant mechanical reasons why the windshield washer does not spray include:

Clogged injectors . Their exit can be blocked by various debris: rust, dirt or small particles. To check the correctness of the guess, you need to stop the supply of working fluid to the nozzles; if this is the case, then the supply of “anti-freeze” will be normal. The solution to this problem lies in replacing the nozzles.
Disconnecting the hose . It may simply fly off while driving on bumpy roads, and then the fluid supply will continue, but the headlight and windshield washer nozzle will remain dry. Sometimes this happens in cars in which the connecting fittings are located on the hood, then when it is closed, the hoses are squeezed. In any case, the deformed or torn tube must be replaced and returned to its place.

Electrical faults

After checking the fluid level, the cleanliness of the injectors and the hose leading to them, it may turn out that all this has nothing to do with it, then the issue is for the following reasons:

Fuse blown . You will need to find the safety block and check the insert; it can be found using the attached diagram, which is usually printed on the cover or in the car’s operating instructions. After checking, if this is indeed the reason, then you need to replace the damaged part
Motor failure . To establish the accuracy of your guess, you should connect a multimeter to the motor terminals and check the voltage when you turn on the washer. If the voltage indicator is normal, but the motor remains inoperative, then the problem lies with it. You can determine which motor has failed by elimination, by moving the pump terminals from the windshield to its rear counterpart.
Washer switch malfunction . It is usually located on the steering wheel. If, after checking the voltage, it is missing, and replacing the motor with a new unit did not help, then it turns out that the windshield washer switch or relay is not working. Only an experienced auto electrician can accurately diagnose a breakdown.
Oxidation of pump terminals . During operation, they can not only oxidize, but also completely fall off, which is why the motor stops pumping liquid. To return everything to working condition, you need to clean the oxidized terminals or replace them with new ones.
