This might be an easy and inexpensive fix of the AC blowing warm air in the car. In simple terms, an AC compressor is a pump which creates the heat by putting the air conditioning refrigerant under extremely high pressure. By testing the wires that go into the relay, you can diagnose if it is the relay itself, or something else that is causing the problem. How they work is by a wire wound magnetic coil that when excited by a electric current, moves a mechanical spring contact inside the relay, completing a circuit. Two of the most important relays in your vehicle that can have a major impact when damaged are the fuel pump relay and starter relay. When the thermostat switches on, a low-voltage signal energizes the appropriate relay. The main issue using DC relay with AC is the contacts might not be spaced enough and you can see arcing.
