Disconnect the radiator fan motor 2P connector. Measure the voltage between fan motor 2P connector terminal No. 2 and body ground. RADIATOR FAN MOTOR 2P CONNECTOR Wire side of female terminals Is there battery voltage? YES – Go to step 9. NO – Repair an open in the wire between radiator fan relay 4P socket terminal No. 3 and radiator 2P connector terminal No. 2. Disconnect the jumper wire. Test the radiator fan motor (see page 10-4). Is the fan motor OK? YES – Repair an open in the wire between radiator fan motor 2P connector terminal No. 1 and body ground G301. NO – Replace the radiator fan motor.

Disconnect the radiator fan switch A 2P connector. Turn the ignition switch ON (II). Measure the voltage between the radiator fan switch A 2P connector terminal No. 1 and body ground. RADIATOR FAN SWITCH A 2P CONNECTOR Wire side of female terminals Is there battery voltage? YES – Go to step 4. NO – Repair open in the wire between the radiator fan switch A connector and under-hood fuse/relay box. Turn the ignition switch OFF and check for continuity between the radiator fan switch A 2P connector terminal No. 2 and body ground. RADIATOR FAN SWITCH A 2P CONNECTOR Wire side of female terminals Is there continuity? YES – Replace radiator fan switch A. NO – Check for open in the wire between the radiator fan switch A connector and body ground. If the wire is OK, check for poor ground at G301. aaa
