The windshield washer system is an important part of every car, ensuring driving safety and driver comfort. But despite the simplicity of the device, not all drivers know how to turn on the windshield washer, especially when it comes to older car models or cars with non-standard controls. In this article, we will take a detailed look at how the washer system works, how to turn it on correctly, and also consider examples for VAZ 2101, 2105, 2106, 2107, 2114 models, as well as Toyota and Mercedes.

How does the windshield washer system work?

The principle of operation of the washer is simple: after pressing a special lever or button, the pump supplies fluid through tubes to the nozzles, which spray it onto the glass. Then the wipers are activated, removing dirt or water. For the system to work, it is important not only to know how to turn on the windshield washer, but also to monitor the fluid level, the condition of the nozzles and pumps.

How to turn on the windshield washer on VAZ

VAZ 2101, 2105, 2106

On classic VAZ models 2101, 2105, 2106, the system is started manually:

A button is installed between the seats or on the front panel (sometimes a mechanical pump).
Press or pump the fluid manually - and the nozzles will spray it onto the glass.
The wipers need to be turned on separately with a toggle switch or switch.

The system is simple, but requires physical effort and regular checking of the condition of the reservoir and hoses.

VAZ 2107

Many drivers wonder how to turn on the windshield washer on the VAZ 2107. In this model, the system is already electric:

Pull the wiper stalk towards you.
At this moment, the pump turns on, and fluid is supplied to the windshield.
The wipers are activated simultaneously.

If the system does not work, check the fuses, reservoir, and electrical contacts.

VAZ 2114

In more modern models, such as the VAZ 2114, it is even simpler:

The windshield washer is turned on by pulling the lever towards you.
If fluid is supplied but the wipers do not turn on, there may be a relay malfunction.
Remember that in winter you need to use a non-freezing fluid.

How to turn on the windshield washer on Mercedes

Mercedes owners also wonder how to turn on the windshield washer on a Mercedes, especially when switching from cars of other brands. The general algorithm:

Turn on the ignition.
Pull the wiper control lever (usually on the left under the steering wheel) towards you.
The washer pump will turn on automatically, and the system will spray the fluid.
The wipers make 2-3 passes, then return to their original position.

On some models, the washer only works when the low beam is on or in a certain temperature range.

How to turn on the windshield washer on Toyota

On most Toyota models, the washer control system is also intuitive:

Pull the steering column switch (usually on the right).
The system activates the fluid supply and the wipers.
In some cases, the headlight washer is activated simultaneously (if the low beam is on).

If the windshield washer does not work, make sure the reservoir is full, the pump is working, and the nozzles are not clogged.

Possible malfunctions and solutions

If you know how to turn on the windshield washer, but the system does not supply fluid, the reasons may be as follows:

Empty reservoir - just add fluid.
Frozen water - use only non-freezing fluid in winter.
Blown fuse - replace it according to the diagram.
Faulty pump - diagnostics and possibly replacement will be required.
Clogged nozzles - clean with a needle or toothpick.

How to use the washer correctly?

Use only special fluids - summer and winter compositions are different.
Do not turn on the washer when the reservoir is empty - the pump may burn out.
Clean the nozzles when necessary.
Regularly check the system before trips, especially in bad weather.

Now you know how to turn on the windshield washer, whether it's a VAZ, Mercedes, Toyota, or any other car. This function seems like a small thing, but it plays an important role in ensuring the safety of the driver and passengers. Monitor the condition of the system, do not forget to add fluid, and use the washer in a timely manner - especially in winter and during rains.
