Mechanical breakdowns
The most common reasons why the VAZ 2114 windshield washer does not work are mechanical damage.
The most common of them are:
- the washer fluid has run out in the tank;
- the pipeline leading to the windshield wiper is clogged;
- the windshield wiper nozzles are clogged;
- the water used as washer fluid froze;
- the hose fell off the pump;
- the hose going to the windshield wiper is pinched;
- The supply hose has ruptured.
Problems related to washer fluid can be solved almost instantly - if it runs out, it should be topped up; if it is frozen, take the expansion tank to a warm room, warm it up, then drain the water or liquid that is inappropriate for the season and fill it with non-freezing one.
If the hose becomes clogged, it should be cleaned (blown out) and then replaced. If the nozzles are clogged, they should also be carefully cleaned using a very thin needle. This operation should be done carefully, without unnecessary effort.
According to the recommendations of car manufacturers, washer fluid should be poured into the expansion tank through a special filter mesh, which will protect the hose and nozzles from possible clogging.
Sometimes it happens that during operation the hose becomes kinked, pinched, or even falls off the expansion tank. In such a situation, it is enough to straighten the hose and install it in its original place. If the hose ruptures (for example, when the coolant freezes), a new one should be installed instead.
Common malfunctions, subtleties of their diagnosis and elimination
Having studied the main components, it is easier to understand why the windshield washer does not work.
Mechanical problems include:
- Absence or insufficient level of liquid - this leads to malfunctions and the impossibility of supplying the composition. If there is liquid, but it does not flow, the system may be frozen (a malfunction typical for the winter period). In such a situation, you need to start the car and warm it up or leave it overnight in a warm place (a heated parking lot is suitable).
- Problems with hoses. There are often cases when the washer supply hose flies off and gets crushed, which occurs due to the poor location of the structure. It is also possible that the element may rupture due to long-term use and aging. It is easy to eliminate the defect by inspecting the system and replacing the faulty component.
- Clogged nozzles are a common problem that occurs when using regular water. Thus, more and more deposits accumulate on the internal surfaces of parts, clogging the passage. Possible rusting of metal components. Clogging of injectors also occurs when a large amount of dirt accumulates during vehicle operation (it is easy to check, just disconnect the hoses, then the flow should be normal, clogged injectors can be cleaned or replaced).
Electrical faults make normal power supply impossible, which means the operation of the device is also disrupted.
- Fuse - may fail and require replacement. To do this, you need to inspect the fuse box, study the diagram, and find the element responsible for the operation of the washer motor. After replacing it, the functionality of the device should be restored.
- Oxidation of terminals and contacts. The appearance of rust on them is common, sometimes the terminals simply fall off. Because of this, the power supply is disrupted and the pump does not pump liquid. The restoration process involves cleaning the terminals and contacts.
- If the windshield washer does not work, check the switch, which is usually located on the steering wheel. To check, you need to use a multimeter, determining the voltage after connecting the electrodes to the motor terminals. A voltage that does not meet the required parameters determines the need to replace the element. If the results are normal, the problem lies in the motor.
- Open circuit – determines the impossibility of transmitting commands. Control is also carried out by checking the voltage - if it is absent, then there is a break (you must first make sure that there is no voltage at the pump terminals).
Considering the simplicity of the design and operation of the washer, the problem is not difficult to find. Often the defects are obvious and easy to fix. And by ensuring proper care of the system and the car, you can prevent the development of problems.
Subtleties of glass washer repair
Intensive use of the system leads to wear and clogging of important components. The recovery process depends on the type of fault.
How to eliminate the main defects with your own hands:
- Clogged injector jets and filter. To gain access to the filter element, you first need to remove the tank. Then, having removed the filter, it is thoroughly cleaned. Injectors become clogged not only with dust and dirt, but also with wax, other compounds, and car cosmetics. In this case, windshield washer repair involves removing external contaminants. If the blockages are deep, use a pin or needle. In advanced cases, in the lower zone of the nozzle, disconnect the hose and insert the wire, moving towards the nozzle (the use of guitar strings and stripped wires is allowed).
- If there are problems with tightness due to a violation of the integrity of the hoses, they are replaced.
- Pump malfunctions are often caused by clogging. What to do if the pump breaks down? First, it needs to be dismantled, inspected, cleaned of dirt and traces of rust (use an eraser). The integrity of the wiring and contacts is also checked. If the above manipulations do not give the desired result, most likely the pump is completely faulty and requires replacement. To do this, first turn off the power supply and wires. Having removed the tank, you need to disconnect the hose and fitting and remove the working fluid. Then, by pushing out the intake, it is easy to gain access to the faulty unit and change it.
Electrical damage
Another answer to the question - why the windshield washer does not work on the VAZ 2114, there may be damage to one or more elements of the electrical circuit of this device. They happen somewhat less frequently, but eliminating them can require significantly more effort.
The main electrical damages are:
- Fuse failure.
- Pump fault.
- A break in the electrical network.
- Faulty steering column switch.
The first reason can be solved simply - you just need to check fuse F7 in the common block and, if it is faulty, replace it with a new one.
If the fuse turns out to be serviceable, then the pump itself should be checked for functionality. To do this, connect it directly to the battery. If the pump motor turns on and the unit itself begins to pump water, then the cause of the malfunction lies somewhere else. If the windshield washer motor of the VAZ 2114 does not work (which can be indicated by complete silence when connecting it to the battery), then the pump should be replaced with a new one.
If it turns out that the fuse and the pump are working, then you should check the electrical system itself. This is best done by “dialing” with a multimeter (tester). If a break is found, the wire will need to be replaced.
The final electrical cause of possible windshield wiper system failure is a damaged steering column switch. You can check this by directly connecting its contacts: 53ah to W or 53ah to 53H. If after this procedure the windshield washer works, then the switch is working. If not, it should be replaced with a new one.
Let's sum it up
The washer sprayer on a VAZ 2109 may not work for many reasons:
- there is no liquid in the tank;
- the motor is broken;
- solenoid valve stuck;
- fuse F7 burned out;
- the steering column switch is broken;
- the wire is broken;
- the injectors are clogged.
All faults are diagnosed by elimination. In some cases, a multimeter is used.
The system is upgraded by installing a high-performance pump, check valve and filter. A common tuning procedure is the installation of two motors and removal of the EMC valves.
Useful video
You can get additional information on this issue by watching the video below:
In the autumn-spring period, it is especially important to keep your car windows clean, because the constantly sticking dirt and dust from the roads, flying out from under the wheels of the “colleagues” of the road traffic, can sometimes significantly spoil visibility, or even force you to dodge an unnoticed obstacle. Of course, the car itself should cope with this problem, but what if the VAZ 2114 windshield washer does not work?
The cause of the malfunction can be either mechanical or electrical in origin. Let's consider both of these options separately.
Pump repair or replacement?
The feasibility of repair is determined by the cost of a new pump. A large number of pumps are non-separable, so for repairs you will have to cut them and then glue the plastic case together. To repair it yourself, it is enough to completely disassemble the motor, clean its insides from dirt, corrosion and growths.
Of course, you won’t find spare parts for the washer pump, so the sealing lip will remain old. If it was this that caused the jamming, then within a year the windshield washer will most likely not work again.
How to remove and wash injectors
The windshield washer nozzles are held in place by plastic clips. To remove the injector without damaging the body, check its number in the original spare parts catalog. By finding a photo of the injector by number, you will see exactly where the latches are located. You can remove the nozzle with a thin slotted screwdriver.
For cleaning, you can use a needle smaller than the diameter of the sprayer hole. We recommend that you first leave clogged injectors in a citric acid solution for some time. After soaking, the deposit can be removed using carburetor cleaner or compressed air.

Electrical reasons why the VAZ 2114 windshield washer does not work.
Reason 1 - the fuse has blown, opening the power supply circuit to the washer pump.
Signs of this particular problem may be a malfunction of the cigarette lighter and the car's heater fan.
Exit: open the fuse box and replace fuse F7.
Reason 2 - the washer pump is faulty due to a burnt-out electric motor or oxidized contacts on the supply wires.
Solution to the problem: repairing the electric motor or cleaning the contacts from oxides.
Reason 3 – there is no current at the pump terminals.
This can be determined using a simple light bulb. Connect it to the wires powering the pump. If there is power, when you press the windshield washer lever, the light should light up. The reason for the lack of power may be a break in the line.
Solution to the issue: ring the line and determine the location of the breakthrough.
Reason 4 – the steering column wiper switch is faulty.
This can be checked by closing contacts 53ah and W or 53ah and 53H.
Solution to the problem: replace the switch with a new one or a used one in excellent condition.
Power fuses
The power fuse and relay block is located on the strip under the panel (dashboard), at the feet of the front passenger; to access you need to bend the plastic side panel.
Depending on the car model, the appearance of the unit may differ slightly from that shown in the photo.
The lowest relay and fuse are the fuel pump. When the ignition is turned on, the fuel pump turns on for 5 seconds to create pressure in the system. Check the ground and contacts of this unit, and also inspect the wiring. The wire from the relay to the pump, which runs along the floor under the casing, may be broken.
The topmost relay is the radiator cooling fan. If it is OK, see the information about fuse F5.
conclusions
If the rear or windshield washer fails, any problem can be quickly resolved, the main thing is to find the cause of the malfunction. In case of problems with nozzles and their complete replacement, it is better to choose these fan-type parts; they wet the glass better. Problems with the integrity or partial deformation of connecting tubes are best solved by connecting new cords. To avoid the listed problems with the washer system, you should use non-chlorinated water in warm weather, and “anti-freeze” water in cold weather.
