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.

1. Check the No. 1 (30 A) fuse in the under-hood fuse/relay box, and the No. 14 (10 A) fuse in the under-dash fuse/relay box.

Are the fuses OK?

YES -

Go to step 2.

NO -

Replace the fuse(s), and recheck. If either fuse blows again, check for a short in the No. 1 (30 A) or No. 14 (10 A) fuse circuits.�

2. Remove the A/C condenser fan relay from the under-hood fuse/relay box, and test it.

Is the relay OK?

YES -

Go to step 3.

NO -

Replace the A/C condenser fan relay.�

3. Measure the voltage between A/C condenser fan relay 4P socket terminal No. 2 and body ground.





Is there battery voltage?

YES -

Go to step 4.

NO -

Replace the under-hood fuse/relay box Under-Hood Fuse/Relay Box Removal and Installation.�

4. Connect A/C condenser fan relay 4P socket terminals No. 1 and No. 2 with a jumper wire.





Does the A/C condenser fan run?

YES -

Go to step 5.

NO -

Go to step 8.

5. Disconnect the jumper wire.

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

7. Measure the voltage between A/C condenser fan relay 4P socket terminal No. 3 and body ground.





Is there battery voltage?

YES -

Replace the under-hood fuse/relay box Under-Hood Fuse/Relay Box Removal and Installation.�

NO -

Repair an open in the BLK/YEL wire between the No. 14 (10 A) fuse in the under-dash fuse/relay box and the A/C condenser fan relay socket in the under-hood fuse/relay box.�

8. Disconnect the jumper wire.

9. Disconnect the A/C condenser fan motor 2P connector.

10. Check for continuity between A/C condenser fan relay 4P socket terminal No. 1 and A/C condenser fan motor 2P connector terminal No. 2.





Is there continuity?

YES -

Go to step 11.

NO -

Repair an open in the wire between the A/C condenser fan relay socket in the under-hood fuse/relay box and the A/C condenser fan motor.�

11. Check for continuity between A/C condenser fan motor 2P connector terminal No. 1 and body ground.





Is there continuity?

YES -

Replace the A/C condenser fan motor Service and Repair.�

NO -

Check for an open in the wire between the A/C condenser fan and body ground. If the wire is OK, check for poor body ground at G201; '07-08 models except SC, '07-08 models SC, '09-11 models.�
