Not working windshield washer fluid what to do? Why doesn't the rear window washer

Do Not underestimate the importance of windshield washer. It can provide comfortable travel on the road in bad weather. Known cases when due to a malfunction of this element people have an accident. Let's see, why doesn't the windshield washer, and how to fix it. First you need to figure out how everything works, and that can cause problems.

The Principle of operation of the device

So, currently, installed the electric pump, it used to be mechanical. Also we have a tank that stores a liquid for wetting the glass. Of course, there are two pipes through which it is fed to the two nozzles. The volume of a tank can be 2,5-5 liters, which is enough for a long period of work, due to the efficiency of the injectors. The electric pump in the tank, is activated podrulevymi switch. Thus the windshield is supplied cleaning fluid, and for a while the wiper switch.

As the working fluid used in conventional water is as for the summer, in winter, when cold there is added a special "antifreeze". Used injectors are of two types: inkjet and fan. It is difficult to say which is better, as those and the second give excellent results. Here, perhaps, and everything about the device and principle of operation of the washer.

Most common problems

Let's start with the most simple and finish defects requiring major repairs of the electric pump and other elements. In the cold season often simply freezes the liquid in the tank. It is not fatal, but we must be careful, because of the expansion of the plastic may burst. We need to melt the liquid inside. To do this, you can use a household hair dryer or something like that.

You should not use chlorinated water. The reason is that this leads to a rapid clogging of the hoses, as a result, the nozzle also clogged. At the wrong time you will have to perform the cleaning. In fact, the most common faults in electrical circuits. Sometimes it's a mechanical issue. Please note that quite often the hoses off, so the liquid simply did not reach the injectors and lost along the way. The same applies to commonplace cracks that appear due to aging or inflection.

What to do if not working motor washer

It is Worth noting that this problem happens not so often. In most cases, you have to completely remove the device and try to repair it. If you press on the lever washer and the pump not buzzing, then this is a clear indication that he has failed. You can inspect the input voltage. If you put 12 In there, and the work is no, you need a replacement or repair. As for attempts to restore the device, then in most cases it does not make sense, as it is cheaper and easier to buy a new product.

But not in a hurry, because if you notice the problem in the cold season, the reason for the lack of buzz may be just freezing. Therefore, you have to try to warm, it can help. If this is the reason, the motor work myself, after thaw, otherwise will have to change it, and now we'll see how to do it.

Replacement pump washer

In fact, there's nothing difficult. We hardly need tools. First of all you need to buy a new washer that will suit your car. The next step is draining the liquid from the reservoir. Next - off "mass" of the battery and the disconnected contact of the pump. The next thing to do is to Unscrew a few bolts, which is attached already empty the washer tank. Basically, if you can get the pump and disconnect the hoses, then this can not be done, but, as practice shows, much better to perform the work when you dismantled the tank.

Then follows the process of Assembly. By and large it is similar to disassembly. Need to retain even the position of the hoses, because if you mess up, you'll have to do extra work. Once you have everything assembled, screw the reservoir back to the bracket. Here, in fact, it is now possible to test for performance.

Not working windshield washer: causes and Troubleshooting

As noted above, there are many problems, which we now discuss. If you are not running the windshield washer, it is quite possible that the whole thing is clogged in the injectors. But just not clean. It is necessary to take distilled water in the ratio 1:1 mix it with vinegar. Takes a few times to turn on and off the washer and to expel all the salt that had gathered in the injectors. It is advisable to leave this solution for a while (1-2 hours), then drive it and flush the system is easy distillata.

We can not say that the reason may be in the fuse. Itmay break or not work due to oxides. This you should check first. Also periodically inspect the integrity of the tank, because the next time the service it can damage and not tell you about it. Since it's plastic, then make it easy enough. Even if the hole is small, the working fluid fast enough to leave the system.

Problems with electrical circuits

We must Not forget that the motor has terminals, and they are oxidized, are bent, etc. Hence, they must be periodically inspected and cleaned. There's nothing difficult. Detachable contacts, take sandpaper, a metal brush or something like that and clean. Then install the terminal and check it.

Another common failure related to electrical, is the failure of the relay switch washer. In this case we need to replace it. Obviously that is not working the washer and when there are problems with the fuse block, but this has already been said above. You need to understand that if mechanical failure can be detected by visual inspection, then the electrical faults, things are slightly different, and therefore the repair will last a bit longer.

Some useful recommendations

If you have a failed injector, they need to change. As a rule, you can choose which you want to install. Advantages of nozzles fan type. They are good because moisten the entire area of the windshield, hence, the wipers will work on hurrah.

If you do not work the rear washer, then most likely the cause liquid leakage, or clogged hose. You can try to resolve the issue using compressed air. To do this, disconnect the hose from injector is disconnected from the motor and blown. Of course, if there's a leak, it won't help. Then you need to completely change the hose. As you can see, the reasons why not running the washer, there are many, but due to the fact that the device itself is not very complicated, all you can find them pretty quickly.

Conclusion

We considered all the causes - both mechanical and electrical. As you could notice, there is absolutely nothing special. The important thing is to understand that if does not work, the windshield washer, then you risk not only themselves and those who sit with you in the car but other road users.

Periodic examinations for the presence of visual defects is also very important. Moreover, it is not recommended to hold on until the quantity of fluid in the reservoir falls to the level low, and to keep at least half volume or even a little more. You can add a little detergent to the glass, remove the remaining dirt and insects will be more effective. All this will allow you to make driving a vehicle in bad weather comfortable and safe.
