A/C Condenser Fan Circuit Troubleshooting

WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Do not use this troubleshooting procedure if the compressor is also inoperative with the A/C on. Refer to SYMPTOM TROUBLESHOOTING INDEX .

Check the No. 47 (30 A) and the No. 10 (7.5 A) fuses in the under-dash fuse/relay box.
Are the fuses OK?

YES - Go to step 2.

NO - Replace the blown fuses, and recheck. If either fuse blows again, check for a short in the No. 47 (30 A) or No. 10 (7.5 A) fuse circuits.
Remove the A/C condenser fan relay from the auxiliary under-hood relay box, and test it (see POWER RELAY TEST ).
Is the relay OK?

YES - Go to step 3.

NO - Replace the A/C condenser fan relay.
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 - Repair open in the wire between the No. 47 (30 A) fuse in the under-dash fuse/relay box and the A/C condenser fan relay.

Connect the 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.

Disconnect the jumper wire.
Turn the ignition switch to ON (II).
Measure the voltage between A/C condenser fan relay 4P socket terminal No. 4 and body ground.
Is there battery voltage?

YES - Repair open in the wire between the A/C condenser fan relay and the ECM/PCM.

NO - Repair open in the wire between the No. 10 (7.5 A) fuse in the under-dash fuse/relay box and the A/C condenser fan relay.

Disconnect the jumper wire.
Disconnect the A/C condenser fan 2P connector.
Check for continuity between A/C condenser fan relay 4P socket terminal No. 1 and A/C condenser fan 2P connector terminal No. 2.
Is there continuity?

YES - Go to step 11.

NO - Repair open in the wire between the A/C condenser fan relay and the A/C condenser fan.

Is there continuity?

YES - Replace the A/C condenser fan motor (see FAN, FAN MOTOR, AND SHROUD REMOVAL AND INSTALLATION ).

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 ground at G301 (see CONNECTOR TO FUSE/RELAY BOX INDEX ).
