## Radiator and Condenser Fans Common Circuit Troubleshooting

1. | Check the No. 10 (20A) and No. 11 (30A) fuses in the under-hood fuse/relay box, and the No. 22 (7.5A) fuse in the under-dash fuse/relay box. Are the fuses OK? YES - Go to 2. NO - Replace the fuse(s), and recheck.n

2. | Remove the condenser fan relay from the under-hood fuse/relay box.

3. | Turn the ignition switch ON (II).

4. | Measure the voltage between the No. 5 terminal of the condenser fan relay 5P socket and body ground. Is there battery voltage? YES - Go to 5. NO - Repair open in the wire between the No. 22 fuse in the under-dash fuse/relay box and the radiator fan relay, and the condenser fan relay.n

5. | Turn the ignition switch OFF.

6. | Reinstall the condenser fan relay.

7. | Make sure the A/C switch is OFF.

8. | Turn the ignition switch ON (II).

9. | Measure the voltage between the No. 6 terminal of ECM/PCM connector B (24P) and body ground with the ECM/PCM connectors connected. Is there battery voltage? YES - Check for loose wires or poor connections at ECM/PCM connector B (24P). If the connections are good, substitute a known-good ECM/PCM, and recheck. If the symptom/indication goes away, replace the original ECM/ PCM.n NO - Repair open in the wire between the radiator fan relay, the condenser fan relay and the ECM/ PCM.n
