As the title suggests, this video will help the interested car enthusiast, if necessary, carry out his own repair of the windshield washer motor .
One of the most common problems for the washer motor, both for branded and cheap Chinese analogues, is a leaking oil seal near the pump, as a result of which washer fluid enters the motor, causing corrosion and jamming.
It is known that the function of the motor is short-term, the washer turns on, the glass is washed and the motor no longer works. The load on it is small, it does not wear out, the whole problem is in that same oil seal. How to solve it - watch the video.
Hi all! The problem of windshield wiper failure is familiar to many. One of the reasons may be the pump pumping water to the system. So today they propose to discuss the windshield washer motor.
Externally, the element is quite small, but plays a vital role in the operation of injectors and wipers. In fact, without it, water will not be able to get from the tank onto the windows, and the wipers will simply begin to crawl across the dry windshield, scratching the surface with settled dust or dirt. There's nothing good here.
Device Features
There are new and old motors. The latter can be found on Soviet cars, or on VAZ 2107, 2108, for example.
Most cars, including the VAZ 2109, 2110, 2114, as well as foreign cars Mitsubishi Lancer, Pajero Sport or Ford Focus, already use new types of washer motors (pumps).
The main components of the washer are:
- nozzles;
- pump (motor);
- reservoir with washer fluid.
Nozzles are used to supply water to the windshield of a car. Therefore, they should be positioned so that the outgoing stream of liquid hits the center of the headplate as much as possible. The pump supplies water to the tank. By the way, on some cars, wash water is supplied not only to the windshield, but also to the main headlights in front and behind.
It doesn't matter what kind of car you have. It could be a Priora, a Hyundai Accent, some Mazda or Toyota. All the washer motors work on the same principle. Although the device, characteristics and appearance may vary.
Pumps supply water or washer fluid. If the windshield washer does not work, most likely the reservoir or the nozzles themselves are broken. They can be replaced or repaired yourself.
How does a windshield washer motor work?
The motor in the windshield washer allows a stream of water or windshield cleaning liquid to be supplied under pressure. In some models, the jet is supplied not only to the front, but also to the rear window. It is not difficult to set up the operation of windshield washer parts, but when the motor breaks down, most car owners contact the service center to replace it. In fact, repairing a motor is quite easy, the main thing is to know a few secrets.

Replacement
If the old motor has failed, there is no point in trying to repair it somehow. To buy a new part, you will have to spend very little money. And the replacement procedure on most cars is extremely simple.
I will describe the main stages of work associated with replacing this element of the windshield cleaning system of any car.
- Turning off the vehicle's power. A safety measure without which further work makes no sense. Be sure to remove the negative terminal from the car. It's simple but important. Otherwise, you not only risk burning the wiring, but also getting an unpleasant electric shock yourself.
- Search for a motor. It all starts with identifying where your windshield wiper motor is located. It depends on your car. On some cars, just lift the hood and you will immediately see the washer reservoir. The motor itself is located on the reservoir (partially inside) of the windshield wiper, into which the liquid is poured. Do you see the tank? If yes, then you are in luck. If not, then you will have to look for it by removing elements of the engine compartment. On some car models, the tank is hidden so that the fender protection has to be removed.
Details of the whole
As you can see, the window washing system is not that complicated. It consists of several simple components: a motor, a tank and injectors. Of course, there are also lines through which the washer fluid passes. The pump pumps liquid, which, under pressure, approaches the tee. Tee - washer fluid distributor. Then it is sprayed through the nozzles directly onto the center of the windshield and spread around the perimeter by the wipers.
Nothing complicated, but at the same time there are a lot of details. In the event of a malfunction, immediately check the tank and its integrity, as well as the nozzle; it may be clogged with dirt that needs to be removed. Next, check the pump - if it buzzes, then everything is in order. If not, disconnect and completely clean, also clean the terminals. Highways are also a fairly important element. They may bend or break somewhere, and the liquid will not pass through. And, of course, the injectors play their role. To save washer fluid, they spray it very sparingly. From this we can conclude that the spray holes are small in diameter. Therefore, there are often cases when they become clogged and the system stops working.
Washer failures, their causes and diagnosis
Most often, the cessation of fluid supply is due to clogged filters. Therefore, first of all, clean the system and eliminate the cause of the breakdown - contamination . If it turns out that the motor has stopped working, then you will need to clean its parts from rust and dust. Replacing the mechanism will only be necessary as a last resort. In some situations, electrical breakdowns occur. This is due to loss of contact on one of the connections. With frequent temperature changes, over time, the motor terminals oxidize, which leads to their complete or partial destruction. Most often, breakdown occurs due to:
- clogged washer nozzles;
- a broken hose;
- fluid leaks;
- washer switch malfunction;
- Damage to motor terminals.
Tip: First, inspect the windshield washer reservoir and clean the system of dirt, and only after that proceed to cleaning the motor.
Do-it-yourself troubleshooting
The main reasons for the lack of washer fluid can be eliminated with your own hands.
Cleaning the injectors
Their replacement and cleaning occurs in the same way and it begins with the removal of these parts, the process is as follows:
- open the hood;
- make sure that they have plastic plugs; if they are present, they must be carefully removed;
- take a flat-head screwdriver and open their spring fasteners to remove the injectors.
Installation of new parts occurs in the reverse order.
To wash the injectors and free them from dirt, you should prepare a special cleaning solution of non-chlorinated water and vinegar, taken in equal proportions. The mixture is mixed well and then poured into the tank. After which you need to press the washer lever, even if the water does not reach the glass, it’s okay. So that the components of the solution have time to break down all the contaminants, you need to leave it in the cleaning system for 2 hours, and then press the lever again. After the dirty solution flows out of the nozzles, rinse the hoses with distilled water.
For sprayers that are too clogged, you need to prepare a wire and, after disconnecting the hose, insert it into the nozzle up to the nozzle.
Replacing the motor
It is quite difficult to repair the motor yourself, so most often it is simply replaced.
Installation of a new device is carried out as follows:
- remove all liquid remaining in the tank from the tank;
- disconnect the contact between the battery and the pump;
- if necessary, you can dismantle the tank, but if manipulations can be carried out with a fixed device, then you don’t have to do this;
- remove the electric pump from the tank and unscrew all the hoses going to it, but just remember their location so that after repair they can all be returned to the correct places;
- connect a new pump to the system;
- screw all the tubes;
- connect the battery to the motor;
- pour liquid into the reservoir.
Check the operation of the motor by pressing the washer lever; if you hear a whirring sound from the pump, then everything went well.
Step-by-step replacement instructions
Despite the fact that different car models have distinctive windshield washer design features, the diagnostic and replacement process is similar. The repair will not take you much time. New components, if needed, are inexpensive and will cost you about 500 rubles. The tools you will need are a flathead and Phillips screwdriver and a set of standard wrenches.
- Using the technical manual for your model, we find the exact location of the tank and motor.
- Turn off the power supply. To do this, disconnect the wires that go to the pump.

When disassembling the pump, it may be discovered that the bushing has become unusable and needs to be replaced. Such a part is inexpensive and when repairing it is better to purchase it in advance to increase the service life of the mechanism.
How to replace (video tips)
If problems arise with the windshield washer, do not delay repairs. In bad weather, you cannot do without cleaning the windshield, and low visibility often leads to emergency situations on the road. Replacing the motor or cleaning it can be done on your own, it will take very little time.
DIY washer motor repair
If you decide to repair your old washer pump, first of all you need to know the structure of the motor. It consists of:
- Cases.
- Housing covers.
- Motor stator.
- Anchors and brush assembly.
It seems somewhat difficult to disassemble the motor itself, since most often (for example, the VAZ 2110 or Zaz sens model), its body is one-piece and is made that way at the factory. It is possible to open the case if you carefully cut it with a hacksaw (it is best to do this in the area of the step, since in the future it will be easier to reconnect the case). Next, using a screwdriver, we separate the parts of the housing, while you need to pull out the stator and armature. the inside of the body , as well as the armature roller and bushings, from dirt, rust and oxidation. The bushings require great attention - they need to be cleaned so that they shine.
Before assembling the pump, you need to check whether the armature shaft rotates freely in relation to the motor housing. In addition, a very important part is the armature shaft seal, because most often it is the culprit of pump failure. If necessary, the oil seal must be replaced. Such oil seals can be purchased in specialized stores or made independently, but with precision observing all the necessary dimensions and clearances.
When assembling the motor, you should lubricate all the bushings and check the rotation of the armature. It is advisable to test the motor by connecting it directly to the battery, then you can finally assemble it. Assembly of the body, which is sawn during disassembly, is carried out using soldering or gluing.
Today there are a huge number of not only original pumps, but also their analogues from various manufacturers. To choose a powerful and high-quality, but at the same time inexpensive electric pump, you need to contact those who have already tested them, or read reviews on the Internet. They are often very informative and will help you make the right choice.
Inspecting the rubber seals
Most often, seals and gaskets are the cause of system failure. This is due to the fact that over time the rubber hardens, cracks, and so on. Accordingly, the gasket does not perform its functions. If during repairs you discover a faulty bushing, replace it. This will significantly extend the life of your pump. The same applies to other seals. We try to throw away everything that looks bad or is cracked and puts in a new one.
