The Automotive HVAC Condenser Fan Circuit, is in charge of extracting heat from the refrigerant outside the vehicle, by blowing outside air through it. It is placed at the front of the car, inside the engine bay, right behind the condenser unit and radiator. In many models, it is separate from the radiator fan motor. The condenser holds compressed refrigerant. The circuitry running the condenser fan, is also as important as the rest of the system. The main difference is in how the fan is actuated. Here are the different circuit variations.

But before we go into it, there's one fact that you must always remember, when analyzing any computerized climate control HVAC system, which is that the engine computer, or ECM always reserves the right to ...
