Electric Cooling Fans: Operation: 3.5RL

Fan control unit regulates radiator and condenser fans. Both fans run whenever engine is running. Fans run at either low or high speed, depending upon engine temperature. If A/C system pressure is greater than normal, both fans run at high speed, regardless of engine temperature. Fan control unit is located under cover on passenger's front floorboard, near PCM/ECM. Fan control unit receives input from radiator fan control sensor, PCM/ECM, and A/C pressure switches.
