Condenser Fan: Description and Operation
How the Circuit Works
Voltage is provided at all times to the radiator fan relay contacts through fuse 57 and to the condenser fan relay contacts through fuse 58. The radiator
fan control module controls power to the coils of the relays.
The radiator fan control module is supplied battery voltage at all times through fuse 58. When the ignition switch ON (II), voltage is also supplied to the
module through fuses 3 and 6 (in the driver's under-dash fuse/relay box).
The relays are grounded by either radiator fan switch A or the 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.
If the engine coolant temperature is more than 107 °C (225 °F) when you turn the ignition switch to LOCK (0), the radiator fan control module will turn
on the radiator fan and let it run for about 15 minutes.
