Condenser HVAC: Description and Operation

Condenser
The condenser is mounted in front of radiator. It consists of a series of coils which cool refrigerant. It is a serviceable and replaceable item.

Condenser Fan
The condenser fan improves air flow through condenser. Condenser will still have a high volume of air flowing through it even if vehicle is standing still. It is powered by an electric motor connected to condenser fan relay. Condenser fan relay is an electrical switching box that closes circuit to condenser fan.

Condenser Fan Relay
With the ignition switch in ON, voltage is provided through the WIPER fuse to the condenser fan relay. When the A/C is turned ON, the condenser fan relay energizes and applies voltage to the condenser fan motor, powering it.
