Condenser Fan: Description and Operation

Battery voltage is supplied at all times through fuse 36 and the left condenser fan motor and also through fuse 37 and the right condenser fan motor to the normally open contacts of the condenser fan relay. With the ignition in ON (II), battery voltage is supplied through fuse 4 and the condenser fan relay coil to the fan control unit. When the control unit receives the condenser fan and A/C request from the climate control unit, it grounds the ORN/BLU wire and energizes the condenser fan relay. The relay contacts close providing a ground for the condenser fan motors. The motors run to remove heat from refrigerant passing through the A/C condensers.
