Electric Cooling Fans: Description: Operation
The voltage supply is taken from fuse 25 to relay 396, regardless of the ignition switch position. See COMPONENT LOCATIONS . When the engine coolant temperature has reached about 92°C (198°F), temperature switch 39 will close, relay 396 will be energized and power will be supplied to the radiator fan motor.
NOTE:
Cars with air conditioning (AC) are equipped with a crimped branch connection, since the fan is also controlled by the AC unit.
