Radiator Fan Circuit Troubleshooting (Short)

Radiator Fan Circuit Troubleshooting (Short)

NOTE: A short in the radiator fan circuit causes the fan to run constantly whenever the ignition switch is ON (11).

1. Disconnect the radiator fan motor 2P connector from the radiator fan control (RFC) unit.
2. Check for continuity between radiator fan motor 2P connector terminal No. 2 and body ground.





Is there continuity?

YES - Repair short in the wire between radiator fan motor 2P connector terminal No. 2 and body ground.

NO - Replace the RFC unit.
