Electromagnetic valve

Electromagnetic valve switches the AC compressor on and off and controls the compressor’s capacity. It’s important to remember that those valves are very sensitive to dust and contamination. They can be easily clogged and thus get locked in a certain position. In this case the vehicle AC system capacity remains the same all the time or the system cannot be activated at all. Electromagnetic valve should be replaced, and this will eliminate the failure. Check for the possible cause of the trouble and remove it, before replacing the valve.
