Condenser Fan: Description and Operation

How the Circuit Works

Voltage is provided at all times to the radiator fan relay contacts through fuse 4 and to the A/C condenser fan relay contacts through fuse 1. With the ignition switch ON (II), voltage is provided to the coils of the relays through fuse 14 (in the under-dash fuse/relay box).

The relays are grounded by either the radiator fan switch or by the ECM/PCM. Grounding the relays energizes their coils and applies battery voltage to the radiator and condenser fan motors. Both fans then run until ground is removed from the relay coils.
