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.
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.
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.
Operating principle, functions and location of the windshield motor
The windshield washer motor delivers a stream of water or cleaning fluid. In some cars, water is also supplied to the rear window. In order to repair a windshield wiper, you need to know how it works.
System design diagram
The tank is a plastic container with a volume of 2.5 to 5 liters. The tank is located under the hood, and on some car models, under the fender. The tank is connected by curved tubes with nozzles that spray liquid, and brushes rub it over the surface.
The washer reservoir motor is responsible for supplying water.
This is an electric motor that is powered by a battery. You can find information about where it is located in the owner's manual, since its location depends on the car model.

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.
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.
During what period is it most likely to lose a “healthy” washer?
Most often, this device fails due to the frequency of use. Therefore, we can predict what time is the most unfavorable for this device.
One of these periods is the time of mud and slush. For others, it’s a time of heat and dust. In both cases, the driver wets the glass as often as possible to get rid of unpleasant contaminants, and a significant load is placed on the washer motor.
