The windshield washer does not work, what should I do? Why the rear window washer does not work?

Do not underestimate the importance of the windshield washer. It is able to provide comfortable travel on the road in non-flying weather. There are cases when, due to a malfunction of this element, people were in an accident. Let's see why the windscreen washer does not work, and how to fix it. First you need to figure out how everything works, and what can be the cause of the problem.

Principle of operation of the device

So, at the present time the electric pump is being installed, before it was mechanical. Also we have a tank in which the liquid for spraying glass is stored. Naturally, there are two tubes through which it enters two sprayers. The volume of the tank can be 2.5-5 liters, which is quite enough for a long period of work, which is due to the economy of the injectors. The electric pump in the reservoir is activated by the steering column switch. Thus, a cleaning liquid is applied to the windshield, and janitors are switched on for a while.

As the working fluid is used ordinary water - this is for the summer period, in winter, when it is cold, special "ice-free" is added there. Injectors of two types are used: jet and fan. It is difficult to say which is better, both those and the second give an excellent result. Here, perhaps, and everything that relates to the device and the principle of the washer.

Common problems

Let's start with the simplest ones and finish the malfunctions that require a serious repair of the electric pump and other elements. In the cold season often freezes liquid in the tank. This is not fatal, but you need to be careful, because of the expansion of plastic can burst. We need to melt the liquid inside. To do this, you can use a household hair dryer or something like that.

It is inadmissible to use chlorinated water. The reason is that this leads to a rapid clogging of the hoses, as a result - the jets are also clogged. At the most inopportune moment, you will have to clean it. In fact, most often there are faults in electrical circuits. Sometimes this is a mechanical problem. Pay attention to the fact that quite often the hoses come off, so the liquid simply does not reach the nozzles and is lost along the way. The same applies to the banal cracks that appear due to aging or inflection.

What to do if the washer motor does not work

It is worth noting that this problem does not happen very often. In most cases, you have to completely remove the device and try to repair it. If you pressed the washer lever, and the electric pump does not hum, it's a clear sign that it's out of order. You can check the incoming voltage. If the put 12 V are available, and there is no work, then replacement or repair is needed. As for the attempt to restore the device, in most cases it does not make sense, since it is cheaper and easier to buy a new product.

But do not rush, because if you notice a malfunction in the cold season, then the reason for the absence of a buzz can simply be freezing. Therefore, you need to try to warm it up, it can help. If the reason is just this, then the motor will work itself after it is lost, otherwise it will be necessary to change it, and now we will see how it should be done.

Replacement of the washer pump

In fact, there is nothing complicated. We practically do not need tools. First of all, you need to buy a new washer that fits your car. The next step is draining the liquid from the tank. Further - disconnecting the "mass" of the battery and disconnecting the contact of the electric pump. The next thing to do is to unscrew a few bolts on which an empty washer tank is attached . In principle, if you can get the electric pump and disconnect the hoses, then this can not be done, but, as practice shows, it is much more convenient to perform work with the dismantled tank.

Then follows the build process. By and large, it is similar to disassembly. You need to keep even the position of the hoses, because if you confuse them, you will have to do extra work. After you have collected everything, screw the tank back to the bracket. That, in fact, and everything, now you can test for efficiency.

The windshield washer does not work: causes and solutions

As already noted above, there are many problems, which we will now talk about. If you do not have a windshield washer, then it's possible that it's all about clogged jets. But they just can not be cleaned. For this, it is necessary to take distilled water and mix it with vinegar in a 1: 1 ratio. You need to turn on and off the washer several times and turn off all the salts that have gathered in the nozzles. It is advisable to leave this solution for a while (1-2 hours), then rinse it and rinse the system with a simple distillate.

One can not help saying that the reason can be in the fuse. It can burn out or not work because of oxides. This you should check first. Also, periodically inspect the integrity of the tank, because with the next maintenance in the service it can damage and not tell you about it. Since it's plastic, it's easy enough. Even if the hole is small, the working fluid will quickly leave the system.

Problems with electrical circuits

Do not forget that the motor has terminals, and they are oxidized, bent, etc. Therefore, periodically they need to be inspected and cleaned. There is nothing complicated. We disconnect contacts, we take sandpaper, a brush for metal or something else in this kind and we clean. Then install the terminal and check it.

Another typical failure associated with an electrician is the failure of the washer switch. In this case, we will need to replace it. Obviously, the glass washer does not work even when there are problems with the fuse block, but this has already been said above. It should be understood that if mechanical damage can be detected during a visual inspection, then the electrical malfunctions are a bit different, hence the repair will last a little longer.

Some useful recommendations

If you have failed nozzles, then they need to be changed. As a rule, you can choose which ones you want to install. The advantages are fan type nozzles. They are good in that they wet the entire area of the windshield, therefore, the janitors will work with a bang.

If you do not have a rear window washer, then most likely the cause is fluid leakage or clogging of the hose. You can try to repair the problem using compressed air. To do this, detach the hose from the side of the injectors, disconnect from the electric motor and blow. Of course, if there is a leak, this will not help. Here you need to completely change the hose. As you can see, there are a lot of reasons why the washer does not work, but thanks to the fact that the device itself is not very complicated, they can all be found quite quickly.

Conclusion

We have considered all the reasons - both mechanical and electrical. As you might have noticed, there is absolutely nothing special here. The main thing is to understand that if the windshield washer does not work, then you put yourself at risk not only yourself and those who sit with you in the car salon, but also other road users.

Periodic examinations for visual defects are also very important. Moreover, it is not recommended to hold out until the amount of working fluid in the tank does not fall to a minimum mark, and hold at least half the volume or even slightly more. You can add a little detergent to the glass, so removing the remnants of dirt and insects will be more effective. All this will allow you to make driving on a vehicle in non-flying weather comfortable and safe.
