Engine cooling fan
With the Ignition Switch in ON or START, the ENG fuse supplies battery voltage to the coil of the engine cooling fan relay. When the engine coolant temperature reaches 207°F (97°C) in the SOHC engine, the Engine Coolant Temperature (ECT) switch closes and grounds the coil, energizing the relay. The engine cooling fan relay contacts close and the COOLING FAN fuse supplies battery voltage to the engine cooling fan motor. The fan motor runs until the coolant temperature drops below 194°F (90°C), the ECT switch opens, the relay is de-energized and the fan motor stops. The DOHC engine employs an ECT sensor to provide an engine coolant temperature signal to the engine control module (ECM). The ECM in turn applies ground to the coil of the engine cooling fan relay, energizing it and powering the fan motor. This fan motor is also activated when the ECM senses air conditioning operation. This reduces coolant temperature in compensation for the additional heat load from the A/C system. In this case, the engine cooling fan relay is grounded through the A/C relay and the ECM.

Condenser fan
With the ignition switch in ON, battery voltage is applied to the coil of the A/C relay. Operating parameters permitting, the coil of the relay is grounded through the ECM whenever the A/C switch is ON. (See Compressor Controls). The A/C relay energizes and supplies battery voltage to the coil of the condenser fan relay. The fan relay then energizes and applies battery voltage to the condenser fan motor, powering it.
