Windshield washer

The windshield washer is a very important part of the car. For information on how the aforementioned eyeglass device is arranged and how to properly operate it, see the article below.

The device and principle of operation of the glass washer

You can get a good stain on the window not only when it is wet and dirty outside, but even when it is hot and sunny and the weather does not bode well. At such moments, it may even be necessary to stop urgently to wash the windshield and possibly the rear window to improve visibility.

Therefore, the washer is designed so that in any weather a jet of water can wet the window so that the wiper blades easily remove dirt. If you do this without first cleaning the glass, there is a risk of damaging it with scratches. And this, as you know, will not help anyone.

Schematic diagram of a windshield wiper

The mechanism of the washing machine consists of several main parts on which the work depends:

• tank;
• bomb;
• windshield washer tube;
• windshield washer check valve;
• nozzles

The tank, as the name suggests, contains wash water. The pump and nozzles supply water to the glass. On some cars, as mentioned above, it is possible to install a rear window washer with fan nozzles. A jet of air will help protect not only the windshield, but also the rear window from the weather.

The pump also consists of several parts:

• brushes (wipers);
• gland;
• wheel.

The windshield washer check valve is designed to pass water to the nozzles. Then the water will instantly flow to the window when the pump is running. This part fits the instrument but is not required for installation. The circuit will work without it.

Causes of malfunction

There are malfunctions that can be fixed with your own hands, the main thing is to find out the cause. We will learn about some possible problems below (the author of the video is MitayTv).

Negligence of the driver

The troubleshooting scheme is simple:

1. If the windshield washer does not work when you give it the correct command, the first thing to look for is fluid in the reservoir. Perhaps it is simply not there, because the mechanism is not responding. To remedy the situation, you need to purchase liquid and pour it into the tank, which in most cases is located under the hood.
2. If the season is winter, and on the street, on top of everything else, there is a burning frost, and you recently changed the fluid, then it may have frozen. To solve this problem, you need to drive the car inside the box for several hours and warm it up to operating temperature. Water is best replaced with a "winter" frost-resistant liquid.

Mechanical damage

There are a few mechanical issues that are also worth noting:

1. If the fluid in the reservoir has been checked and everything is in order, but the problem has not disappeared, it is possible that the water does not reach the nozzles. In this case, it is advisable to check the windshield washer hose from the pump to the nozzles to see if it is broken. It is possible that the windshield washer hose could not only break, but also come off or stretch out a lot. And if a washer tee is installed, then all three contacts should be checked.
2. If the nozzles are clogged, and this can happen very often when using ordinary running water from the tap. You can check if the part is dirty with a stable water supply. If water flows freely through the hose, the nozzles must be cleaned or replaced.

Electrical breakdowns

Since the entire washing process works with electricity, it can be assumed that the malfunction that has occurred is precisely due to the fact that the power supply was turned off.

If the pump does not pump water and does not supply it to the nozzles, the following reasons should be considered:

1. The fuse has blown. In the fuse box, you need to find the one that is responsible for supplying water to the windshield and visually and experimentally diagnose the malfunction.
2. There was a problem in the chain of transmission of commands from the vehicle control system to the device. If the switch is broken or the mechanism does not respond to commands in any way, there is a possibility that there are breaks in the electrical circuit. To check for a malfunction, you need to check with a multimeter the absence of voltage at the pump terminals of the device.
3. Failure of the pump itself. If water gets on the terminals, the contacts may oxidize and the glass washer will stop working.

Conclusion

A washing machine, as we found out, is quite an important detail for a car. This is a convenient mechanism for the safe passage of the driver and passengers, as well as a device that protects the glass from dirt, dust, precipitation and scratches.

You need to resolve the job failure as follows:

1. First of all, check the liquid in the tank of the device. If it doesn't exist, fill it out. In winter, it is necessary to provide the windshield washer with frost-resistant liquid.
2. Then carefully inspect all parts of the mechanism for damage and defects.
3. Check all electricity, as well as contacts, wiring, circuits and, of course, the fuse.
