A/C Condenser Fan High Speed Circuit Troubleshooting

A/C Condenser Fan High Speed Circuit Troubleshooting

NOTE:

- Do not use this troubleshooting procedure if the radiator fan and/or the A/C compressor is inoperative. Refer to the symptom troubleshooting index.
- Before performing symptom troubleshooting, check for powertrain DTCs Initial Inspection and Diagnostic Overview.
- If A/C refrigerant pressure is abnormal, the radiator fans are controlled based on engine coolant temperature.

1. Check the No. 30 (10 A) fuse in the under-dash fuse/relay box.

Is the fuse OK?

YES -

Go to step 2.

NO -

Check for a short in the No. 30 (10 A) fuse circuit.�

2. Remove the fan control relay from the auxiliary under-hood relay box, and test it Power Relay Test.

Is the relay OK?

YES -

Go to step 3.

NO -

Replace the fan control relay.�

3. Check for continuity between fan control relay 5P socket terminal No. 2 and body ground.





Is there continuity?

YES -

Go to step 4.

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.�

4. Turn the ignition switch to ON (II).

5. Measure the voltage between fan control relay 5P socket terminal No. 5 and body ground.





Is there battery voltage?

YES -

Repair an open in the wire between the fan control relay and PCM connector A (49P).�

NO -

Repair an open in the wire between A/C diode A and the condenser fan control relay.�
