Windscreen washer motor. Where is? Maintenance and repair. Windscreen washer motor

The windscreen washer pump provides sufficient pressure in the system to supply water to the glass. This is one of the most important knots in the car, which is necessary always, and not only in bad weather. Let's understand with you, where the windscreen washer motor is installed , what are its features and how is replacement and cleaning performed.

The principle of the motor

To create the necessary pressure and water supply, this motor is used. Its design is different depending on the brand. This is due to the fact that sometimes the water supply is required not only on the windshield, but also on the rear view. In general, the principle of operation does not differ from that characteristic of any other water pump, it simply has small dimensions and works not only with water, but also with a washing liquid, that is, in an aggressive environment. The windscreen washer motor may fail, like any other unit in the car, but unlike the same engine, it is easy for every driver to repair it on its own.

Typical causes of node failure

For a long time of car maintenance, most car service specialists distinguish the following "standard" motor breakdowns:

• Terminal damage;
• Hose disconnection;
• Clogged injectors;
• Malfunction of the switch of a washer.

It is these problems that are most often encountered. The most banal and simple - jumped off the hose under the hood. The liquid enters and simply pours out into the engine compartment. In general, the problem is uncritical, it's enough just to fix the hose - and everything will immediately work.

As the long-standing practice shows, the mechanism itself is simple and extremely reliable, so it rarely fails. Another thing is that the contacts are oxidized and may not give the desired signal. Or everything was clogged with rust and dirt so much that the pump could not push this cork. Situations are different, in any case if the windscreen washer does not work, you need to understand and see what's the matter. Sometimes the reasons are on the surface.

Details of a single 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 highways along which the washer fluid passes. The pump pumps fluid that comes under pressure to the tee. Tee - distributor washer fluid. Further through the nozzles it is sprayed directly to the center of the windshield and wipers are carried around the perimeter. Nothing complicated, but at the same time there are many details. In the event of a malfunction, immediately check the reservoir and its integrity, and also the nozzle, it may have been filled with dirt, which must be removed. Next, check the pump - if it buzzes, then everything is in order. If not, disconnect and fully clean, also clean the terminals. The highways are also quite an important element. They can either bend over or get over, and the liquid will not pass. And, of course, the injectors play their part. To save the washer fluid, they spray it very sparingly. From this it can be concluded that the holes for spraying a small diameter. Therefore, cases when they are hammered and the system ceases to work are not uncommon.

How to replace the windscreen washer motor

As noted above, the design of the motor, depending on the car brand, may differ. This also applies to its location. Nevertheless, if you can find the windshield washer reservoir, there should be no problems. What is needed from the instrument is a conventional flat and cross screwdriver, as well as a set of keys.

As for the components, their price tag is small. Purchases will cost 500-1 500 rubles, depending on what you buy. Next go directly to the replacement. We find the tank and the motor. Disconnect the terminals, they should be checked immediately. If there is a large amount of rust, then it must be carefully removed and try to test the system's performance.

We continue the repair work

After you have determined where the windscreen washer motor is located and detached it, you must perform the following steps. Drain the fluid, if there is one in the system. To do this, disconnect the hose and the union. Next, you need to push the fence out of the sealing bush. The easiest way to do this is by a conventional flathead screwdriver. At the same time, we try not to damage anything, since the products are fragile enough. Now we can turn off the pump from the tank and clean it. You can clean it in any convenient way, best of all with an ordinary eraser - simply and fairly quickly.

How much does the windshield washer in case of breakage? If the domestic car, then a couple of hundred rubles, if the foreign car - more expensive. Usually 1 000 or more. But it needs to be changed only if there are obvious mechanical damages or critical wear.

We inspect rubber seals

Omentums and gaskets are the most common cause of the system's inoperability. It is due to the fact that over time the rubber dies, crackles and so on. Accordingly, the gasket does not fulfill its functions. If during repair you have found out the malfunction of the bushing, then replace it. So you will significantly extend the life of your pump. The same applies to other omentums. Everything that looks bad or cracked, we try to throw out, and put a new one.

We approach the final part

Almost always, the windscreen washer motor is not dismountable. That is, you will not be able to inspect its internal parts, such as a stator and an anchor. The housing is poured in the factory, only replacement of the failed part is provided. But we are not looking for simple ways and we can disassemble the unseparable. For this we need a hacksaw for metal. With it, we make a neat cut on the step of the pump and use a flat screwdriver to divide it into two halves.

From the stator of the motor accurately we get an anchor with brushes. It is important not to bend anything or break it. Then we take up cleaning. We rub everything to shine and try to completely get rid of corrosion. We change the stuffing box, because of which the fluid leaked, and we collect everything back. To do this, use a soldering iron or glue. We check the working capacity. Everything should function without the slightest sign of wear.

Finally

You should never neglect safety on the road. It would seem that the windscreen washer motor has a tiny size, what kind of responsibility can it have? And if you seriously think, then imagine that at a speed of 120 km / h in the windshield, it is sprayed with dirt, and you can not clean it, or the wipers simply smear dirt, and no water comes from the nozzles. As a result - emergency braking or an accident. For this simple reason, even though a small simple node needs to be serviced periodically. Carry out cleaning injectors and trunks at least once a year, and the motor can be inspected even less often, but it is still worth doing. If the system is thoroughly cleaned from corrosion and other kinds of pollution, then you can not expect a failure at the most inopportune moment. Usually, if the motor works its resource, it signals it in a variety of ways, so you can purchase spare parts in advance. All car systems like care and maintenance, this node is by no means an exception. Therefore, if the windscreen washer does not work, the problem should be solved as soon as possible.
