A/C Condenser Fan High Speed Circuit Troubleshooting
A/C Condenser Fan High Speed Circuit TroubleshootingNOTE:
- Do not use this troubleshooting procedure if the radiator fan and/or the A/C compressor is inoperative. Refer to the symptom troubleshooting index. Heating/Air Conditioning
- Before performing symptom troubleshooting, check for powertrain DTCs.
1. Check the No. 30 (7.5 A) fuse in the under-dash fuse/relay box.
Is the fuse OK?
YES - Go to step 2.
NO - Replace the fuse, and recheck. If the fuse blows again, check for a short in the No. 30 (7.5 A) fuse circuit
2. Remove the fan control relay from the auxiliary under-hood relay box, and test it.
Is the relay OK?
YES - Go to step 3.
NO - Replace the fan control relay.
3. Turn the ignition switch ON (II).
4. Measure the voltage between the No. 5 terminal of the fan control relay 5P socket and body ground.
Is there battery voltage?
YES - Go to step 5.
NO - Go to step 9.
5. Turn the ignition switch OFF.
6. Check for continuity between the fan control relay 5P socket No. 2 terminal and body ground.
Is there continuity?
YES - Go to step 7.
NO - Check for an open in the wire between the fan control relay and body ground. If the wire is OK, check for poor ground at G201.
7. Remove the radiator fan relay from the auxiliary under-hood fuse/relay box.
8. Check for continuity between the fan control relay 5P socket No. 3 terminal and the radiator fan relay 4P socket No. 3 terminal.
Is there continuity?
YES - Repair open in the GRN wire between the radiator fan relay No. 3 terminal and the PCM A5 terminal.
NO - Repair open in the wire between the fan control relay and the radiator fan relay.
9. Remove A/C diode A from right engine compartment wire harness.
10. Using the diode setting on a DVOM, check for current flow in both directions between the A/C diode A No. 1 and No. 2 terminals.
Is there current flow in only one direction?
YES - Go to step 11.
NO - Replace A/C diode A.
11. Turn the ignition switch ON (II).
12. Measure the voltage between the A/C diode 4P socket No. 2 terminal and body ground.
Is there battery voltage?
YES - Repair open in the wire between A/C diode A and the condenser fan control relay.
NO - Repair open in the wire between the No. 30 (7.5 A) fuse in the under-dash fuse/relay box and A/C diode A.
