Radiator Cooling Fan Motor Relay: Description and Operation
RADIATOR COOLING FAN RELAY - PCM OUTPUT
The radiator cooling fan relay is a 5-pin, solenoid type, mini-relay. It is located in the Power Distribution Center (PDC). Refer to label on PDC
cover for relay location.
The electric radiator cooling fan is controlled by the Powertrain Control Module (PCM) through the radiator cooling fan relay. The PCM will
activate the relay after receiving inputs from the Engine Coolant Temperature (ECT) sensor and/or an air conditioning ON/OFF signal.
Not Equipped With A/C: The relay is energized when engine coolant temperature is above approximately 103 °C (217 °F). It will then
de-energize when engine coolant temperature drops to approximately 98 °C (208 °F). Refer to Cooling Systems for additional information.
Equipped With A/C: In addition to using coolant temperatures to control cooling fan operation, the cooling fan will also be engaged when the air
conditioning system has been activated. Refer to Heating and Air Conditioning for additional information.
