Using the example of the windshield washer of a VAZ 2109 (2108, 21099) car, we will analyze the reasons for its malfunction and what to do in each specific situation.
The windshield washer does not work, reasons
All causes of washer malfunction can be divided into two groups: mechanical and electrical.
Let's look at the mechanical ones first.
- Clogged washer nozzles
The windshield washer nozzles (sprays) on the VAZ 2109 are installed on the hood. The washer fluid outlet holes in them can become clogged both from the outside and from the supply pipes.
- Damage to washer tubes
The tubes may become pinched or twisted due to improper installation. Either it becomes leaky, and then the washer fluid will leak out or its pressure will decrease.
Now electric
- The washer motor is burnt out or the solenoid valve is faulty
- The electrical circuit for turning on the washer motor and unlocking the solenoid valve is faulty
There may be a break in its connections or elements.
What to do if the washer does not work?
To start, just turn it on and listen to the whirring of the electric motor in the coolant reservoir. If it buzzes, it means the electrical circuit is OK. In this case, you need to check the cleanliness of the nozzles, the integrity and correctness of the tubes.
In the electrical circuit for turning on the windshield washer, the fault can most easily be found by looking at its operation diagram.
The voltage supply to the washer and valve is shown by red arrows
We turn on the purifier and sequentially check the presence of voltage at several control points. For example, on the tips of the “positive” wires to the washer motor and solenoid valve. So, if it is present there, we can say that they “burned out”. Or at terminal “53ah” of the steering column switch - check whether voltage is supplied from the ignition switch.
Special attention to the right steering column switch, since in many cases it is the culprit for the washer failure to work. Sometimes the cause of the malfunction is an oxidized contact in its chip. It is necessary to check whether there is voltage at its “W” output when the washer is turned on.
Along the way, you should pay attention to fuse F17 in the mounting block and the reliability of fastening the “mass” washer wire.
We replace or repair faulty sections and elements of the electrical circuit.
Notes and additions
A little information about how the windshield washer works on a VAZ 2109 car.
The windshield washer only works when the ignition is on. In this case, the contacts of the ignition relay “30” (plus from the generator) and “15/2” of the ignition switch (output to the washer) are closed. See diagram.
To turn on the windshield washer, the driver moves the lever of the right steering column switch towards himself to a non-locking position (in any other position of the lever - in any operating mode of the wipers).
In this case, contacts “53ah” (plus from the ignition switch) and “W” (output to the pump motor and washer valve) inside the switch are closed. Then, through the mounting block (red or pink wire), voltage is supplied to the washer pump electric motor located in the washer reservoir and the washer shut-off solenoid valve installed nearby. The valve opens, the washer pump motor pumps fluid, spraying the windshield through the nozzles (sprayers) on the hood.
Mechanical reasons for the malfunction of the windshield washer of the VAZ 2114
Reason 1: sand or dirt gets in, and, as a result, the windshield wiper pipe becomes clogged.
Solution: remove and blow out the washer fluid pipes. Note that for preventive purposes, it is important to fill the washer fluid into the tank through a special mesh filter; this will protect both the fluid from getting contaminants into it at the time of filling, and the pump from the possibility of jamming.
Reason 2 - the tank has run out of windshield washer fluid.
The solution to the problem is very simple - just pour washer fluid or water into the tank (note that at sub-zero temperatures plain water cannot be used).
Reason 3 - clogged windshield wiper nozzles (nozzles).
Solution to the issue: cleaning the holes of the windshield wiper nozzles using a thin needle.
Reason 4 – the washer fluid has frozen.
If liquid that is inappropriate for weather conditions is poured into the tank, it may freeze in the pipes and the tank itself. If there are no special heaters, then you need to put the car in a warm garage and thereby solve this problem (the liquid will freeze), more details.
Reason 5 - rupture of the pressure main pipeline.
It can occur if the nozzles are clogged with debris or small stones, since such circumstances can lead to the formation of excess pressure inside the system, which, in turn, leads to rupture.
Solution to the problem: find the rupture and repair it - replacing part of the worn pipeline using special conductors.
Reason 6 - the hose has come off the feed pump.
Solution: installing a hose on the pump and then tightening it with a clamp.
Reason 7 – a crushed hose supplying washer fluid to the injectors.
Solution to the issue: Most often this happens due to the incorrect transition of the hose on the hood to the windshield wiper nozzles. Find the location of the bend and eliminate it.
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.
Tips for motorists
Many drivers, during the spring thaw, when dirt flies from under the wheels of passing cars into the windshield, discover that the windshield is malfunctioning. As always, the rhetorical question arises, why does the washer not work on the VAZ-2114 ?
In this case, the malfunction may be hidden in two main reasons - mechanical and electrical. Let's look at both in order.
Mechanical reasons include:
- clogging of pipelines for washer fluid;
- clogged jets (washer nozzles);
- lack of washer fluid in the tank;
- Freezing of washer fluid in the tank, pipelines or nozzles.
Since it is not difficult to deal with mechanical reasons - just clean the pipelines, nozzles, add liquid or warm it up and everything will work, electrical ones can cause trouble.
Electrical reasons
First of all, it is necessary to determine the serviceability of the circuit fuse, this is not difficult to do, you just need to turn on the heater fan or cigarette lighter, if they malfunction, we can make an unambiguous conclusion that fuse F7 in the mounting block has failed. We replace it and use the washer. If after replacing the fuse it soon fails again, we look for the cause of the malfunction further.
We check the serviceability of the heater pump motor; to do this, you can apply voltage from the battery to the motor contacts; if the motor “hums” and the washer fluid begins to flow, we conclude that the pump is serviceable. If the motor hums but no liquid flows or does not hum at all, then the pump is faulty, replace it with a new one.
Having determined the serviceability of the pump, we move on to identifying the reasons for the lack of voltage at its terminals. To do this, you can use a control light connected to the wires supplying the pump. By pressing the washer lever, we determine the presence of voltage; if it is absent, we check the contacts of the supply wire and detect an open circuit. If there is no open circuit and there is no voltage from the washer switch, then the cause is a malfunction of the switch. You can check it by closing contacts 53ah and W or 53ah and 53H. Having identified a malfunction of the switch, we replace it with a new one.
Thus, the washer is one of the simplest car systems, but if it malfunctions, a large accident can occur, so monitoring its performance is vital.
We find out why the VAZ 2114 windshield washer does not work
Sometimes car enthusiasts are faced with the fact that the VAZ 2114 washer does not work. This seemingly harmless problem can actually lead to very serious consequences. After all, the washer is designed to clean the windshield from dirt and various debris that gets on it, which is sometimes impossible to remove with the help of wipers alone.
Such pollution significantly impairs visibility through the windshield, and this, in turn, can make driving on the road unsafe.
It should be remembered that according to the law, driving a car whose washer has failed is strictly prohibited. It will also not be possible to pass a technical inspection with a faulty washer.
The washer itself is quite simple, and its most important components are:
- tank;
- pump with motor;
- hose;
- nozzles;
- washer fluid level sensor.
We’ll tell you below why breakdowns happen even in such a simple unit and how to fix them yourself.
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.
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.
VAZ-2115 fuses and relays, electrical diagrams
VAZ 2115 is a fairly common car model that can often be found on the streets of Russian cities. When something breaks down and an electrical device stops working, it causes inconvenience to the driver and passengers. In case of serious malfunctions, movement may become impossible or dangerous. For example, if the headlights stop working at night or the car stops starting.
Most of the causes of such problems lie in the fuse box. It is necessary to periodically check the fuses and relays of the VAZ-2115, clean and replace parts that have become unusable. This article will discuss which fuses are responsible for what in the “fifteenth” and how to solve many electrical problems.
Why the windshield washer does not work on the VAZ-2114
VAZ-2114 drivers sooner or later encounter the fact that the windshield washer stops working. Some are negligent about such a malfunction, stalling for time instead of figuring it out on their own or contacting a car service center, and in vain! Meanwhile, this seemingly insignificant breakdown not only can, but over time leads to more serious malfunctions. The task of the washer is to clean the windshield from various dirt, dust, adhering particles and other things, and it is very important that this element is in good working order, because wipers are not always ready to cope with this task on their own. Why can a washer malfunction be dangerous? Because while driving on a busy highway, the windshield of the car must be clean. If this is not the case, then the risk of disaster increases significantly.
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.
What does the washer consist of?
This element of the car is quite simple in design and consists of:
- tank;
- pump with motor;
- hose;
- nozzles;
- washer fluid level sensor.
As you can see, nothing overly complicated, however, even here malfunctions occur. Read our article about the reasons for this and how to neutralize them without contacting a service center.
Damage to the washer can be mechanical or electrical. The former are much more common than the latter.
Design of the washer on the “nine”
The diagnostic procedure is perceived as more accessible if you are familiar with the design of the module. And here it is, almost like on the Lada Vesta - it consists of simple elements:
- tank;
- 2 motors (rear and front);
- pipelines;
- 3 injectors (two on the front of the hood, one on the rear);
- wiring.
This concept has become widespread on new hatchbacks. Carburetor versions have a different layout. One motor and two electromagnetic valves (EMVs) are installed there, distributing, respectively, to two channels.
Mechanical faults
In the VAZ-2114 car, the most common mechanical breakdowns are:
- Lack of washer fluid in the tank.
- The hose that goes to the windshield wiper is pinched or the line leading to it is clogged.
- Clogged windshield wiper nozzles.
- Broken supply hose.
- The water used as glass washer may have frozen.
- Clogged windshield wiper nozzles.
- The pump fell off the hose.
If the problem is that the liquid used by the windshield wiper has run out, then the solution is very simple - you need to top it up. Frozen water can be warmed up if the tank is placed in a warm room, after which the “out of season” water is drained and unfrozen water is used.
In a situation where the hose is clogged, it must be cleaned and then replaced. Clogged nozzles are delicately cleaned using a thin needle.
Note: it is recommended to fill the washer fluid into the expansion tank using a special filter mesh. It prevents clogging of the hose and nozzles.
Drivers may experience that the hose becomes pinched, bent, or even falls off the tank during operation. In this case, you just need to straighten it and put it in place. When the hose ruptures (this can happen if the coolant is frozen), it needs to 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.
