Radiator Cooling Fan Control Module: Description and Operation

The Cooling Fan System consists of one-speed fan and an electric motor. The Electric Cooling Fan operates only when the Ignition Switch is in RUN.

The Integrated Control Module and the Electronic Engine Control (EEC) Module control the Electric Cooling Fan.

The Electric Cooling Fan turns on when the engine temperature is higher than normal (on at 102~C, off at 99~C), or A/C is on and vehicle speed does not provide enough airflow (on at 52 mph or below, off at 45 mph).
