Do not underestimate the importance of a windshield washerglass He is able to provide comfortable movement on the road in non-flying weather. There are cases when due to a malfunction of this element, people got into accidents. Let's see why the windshield washer does not work, and how to fix it. First you need to figure out how everything works, and what could cause a problem.
The principle of the device
Итак, в настоящее время устанавливается electric pump, before it was mechanical. We also have a tank in which the liquid for sprinkling glass is stored. Naturally, there are two tubes through which it goes to two nozzles. The volume of the tank can be 2.5-5 liters, which is quite enough for a long period of work, due to the efficiency of the injectors. The electric pump, located in the tank, is activated by the steering column switch. Thus, a cleaning fluid is supplied to the windshield and wipers are turned on for a while.
As the working fluid used conventionalwater is as regards the summer period; in winter, when it is cold, they add a special non-freezing bottle. Two types of nozzles are used: jet and fan. It is difficult to say which is better, both those and the latter give an excellent result. Here, perhaps, all that relates to the device and the principle of operation of the washer.
Common problems
Давайте начнём с наиболее простых и закончим malfunctions that require serious repair of the electric pump and other elements. In the cold season it is often easy to freeze the 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.
Chlorinated water must not be used.This is due to the fact that this leads to a rapid clogging of the hoses, as a result - the nozzles are also clogged. At the most inopportune moment you have to do the cleaning. 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 jump off, so the fluid simply does not reach the nozzles and is lost along the way. The same applies to the banal cracks, which appear due to aging or bending.
What to do if the washer motor does not work
It is worth noting that this problem does not happenso 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 buzz, then this is a clear sign that it has failed. You can check the incoming voltage. If there are 12 V installed, but 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.
Но не спешите, ведь если вы заметили неполадку в the cold season, the reason for the lack of buzz may just be freezing. Therefore, you need to try to warm it up, it can help. If the reason is in this, then the motor will work itself after it thaws, otherwise you will have to change it, and now we will see how to do it.
Replacing the electric pump washer
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 stage is to drain the fluid from the tank. Next - disable the "mass" of the battery and disconnecting the contact of the electric pump. The next thing you need to do - is to unscrew a few bolts, which is attached to an already empty washer tank. In principle, if you can get the electric pump and disconnect the hoses, then you can not do this, but, as practice shows, it is much more convenient to perform work with the tank removed.
Далее следует процесс сборки.By and large, it is similar to disassembly. It is necessary to maintain even the position of the hoses, because if you mix them up, you will have to perform additional work. After you have collected everything, screw the tank back to the bracket. Here, in fact, that's all, you can now test for performance.
The windshield washer does not work: the causes and their elimination
As noted above, there are manyproblems, as we now talk. If the windshield washer does not work for you, then it is quite possible that it is all a matter of clogged injectors. But they just do not clean. To do this, take distilled water and in a 1: 1 ratio, mix it with vinegar. It is necessary to turn the washer on and off several times and drive out all the salts that have gathered in the nozzles. It is advisable to leave this solution for a while (1-2 hours), after which it should be removed and the system washed with a simple distillate.
We can not say that the reason may bein the fuse. It may burn out or not work due to oxides. This you should check first. Also, periodically inspect and the integrity of the tank, because at the next MOT in the service it can be damaged and not tell you about it. Since it is plastic, it is quite simple to make it. Even if the hole is small, the working fluid will quickly leave the system.
Electrical Circuit Problems
Do not forget that there is a little engineterminals, and they are oxidized, bent, etc. Therefore, periodically they must be inspected and cleaned. There is nothing difficult. Disconnect the contacts, take the sandpaper, brush for metal or something else like that and clean. Then install the terminal and check it.
Another typical damage associated withAn electrician is a failure of the washer relay 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 box, but this has already been said above. It should be understood that if mechanical damage can be detected by visual inspection, then the situation with electrical faults is a little different, therefore, the repair will last a little longer.
Some useful recommendations
Если у вас вышли из строя форсунки, то их нужно to change. As a rule, you can choose which ones you want to install. The advantages of fan-type nozzles. They are good because they completely moisten the entire area of the windshield, therefore, the wipers will work with a bang.
If your rear window washer does not work,this is most likely due to fluid leakage or clogged hose. You can try to fix the problem with compressed air. To do this, disconnect the hose from the side of the injectors, disconnect from the electric motor and purge. Of course, if there is a leak, it 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 due to the fact that the device itself is not very complicated, all of them can be found quite quickly.
Conclusion
We looked at all the reasons - as mechanical,and electric. As you can see, there is absolutely nothing special. The main thing is to understand that if the windshield washer does not work, then you put at risk not only yourself and those who are sitting with you in the car, but also other road users.
Periodic inspections for the presence of visualdefects are also very important. Moreover, it is not recommended to reach the level until the amount of working fluid in the tank drops to the minimum level, and to keep at least half the volume or even a little more. You can add a little detergent to the glass, so removing remnants of dirt and insects will be more effective. All this will allow you to make a ride on a vehicle in non-flying weather comfortable and safe.
