Condenser Fan Circuit Troubleshooting (Except Type S Model)

WARNING: This page is about a different car, the 2003 Acura 3.2CL and 2002 Acura 3.2CL. However, it is still accessible from the selected car via links, so may be relevant.

Check the No. 58 (20 A) fuse in the under-hood fuse /relay box, and the No. 3 (7.5 A) fuse in the driver's under-dash fuse/relay box.
Are the fuses OK ?
1. YES : Go to step 2.
2. NO : Replace the fuse(s), and recheck.
Remove the condenser fan relay from the underhood fuse/relay box, and test it (see RELAYS ).
Is the relay OK ?
1. YES : Go to step 3.
2. NO : Replace the condenser fan relay.
Measure the voltage between the No. 1 terminal of the condenser fan relay 4P socket and body ground.

Does the condenser fan run ?
1. YES : Go to step 5.
2. NO : Go to step 9.
Disconnect the jumper wire.
Turn the ignition switch ON (II).
Measure the voltage between the No. 3 terminal of the condenser fan relay 4P socket and body ground.

Is there battery voltage ?
1. YES : Repair open in the wire between the condenser fan relay and the radiator fan control module.
2. NO : Perform the radiator and condenser fans circuit troubleshooting C (see TROUBLE SHOOTING ).
Disconnect the jumper wire.
Disconnect the condenser fan 2P connector.
Check for continuity between the No. 2 terminal of the condenser fan relay 4P socket and the No. 2 terminal of the condenser fan 2P connector.

Is there continuity ?
1. YES : Replace the condenser fan motor.
2. NO : Check for an open in the wire between the condenser fan and body ground. If the wire is OK, check for poor ground at G201.
