Radiator Fan Control Module

The radiator fan control module is supplied battery voltage at all times through fuse 39. When the ignition switch is in its "on" (II) or "start" (III) position, voltage is supplied through fuse 4.

When the ignition switch is in its "on" (II) position, battery voltage is also supplied to the radiator fan control module through fuse 8. The module is grounded at G401.

The radiator fan control module turns on the condenser fan and radiator fan for engine and refrigerant cooling whenever the A/C is on.

If the engine coolant temperature is more than 97° C (207° F) when you turn the ignition switch to "lock" (0), the radiator fan control module will turn on the radiator fan and let it run for about 15 minutes.
