NOTE: Do not use this troubleshooting procedure if only one fan is inoperative, or it the compressor is inoperative, refer to the symptom troubleshooting index.
| 1. | Check the No. 9 (20A) and No. 11 (20A) fuses in the under-hood fuse/relay box, and the No. 30 (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. 3 terminal of the condenser fan relay 4P socket and body ground. Is there battery voltage? YES - Go to 5. NO - Repair open in the wire between the No. 30 fuse in the under-dash fuse/relay box 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, and the engine coolant temperature is below 30°C (199°F). |
| 8. | Turn the ignition switch ON (II). |
| 9. | Measure the voltage between the No. 12 terminal of ECM/PCM connector E (31P) 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 E (31P). 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 |
