A/C Condenser Fan Circuit Troubleshooting

NOTE: Do not use this troubleshooting procedure if the fans are also inoperative with the A/C on. Refer to the symptom troubleshooting index.
  1. 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 fuses, and recheck. If the fuses blow again, check for a short in the No. 47 (30 A) and No. 10 (7.5 A) fuses circuit.■
Is the relay OK?
YES -
Go to Step 3 .
NO -
Replace the A/C condenser fan relay .■
  1. Measure the voltage between the No. 2 terminal of the A/C condenser fan relay 4P socket 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.■

  1. Connect the No. 1 and No. 2 terminals of the A/C condenser fan relay 4P socket with a jumper wire.
Does the A/C condenser fan run?
YES -
Go to Step 5 .
NO -
Go to Step 8 .
  1. Disconnect the jumper wire.
  1. Turn the ignition switch to ON (II).

  1. Measure the voltage between the No. 4 terminal of the A/C condenser fan relay 4P socket and body ground.
Is there battery voltage?
YES -
Repair open in the GRN 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.■
  1. Disconnect the jumper wire.
  1. Disconnect the A/C condenser fan 2P connector.

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

  1. Check for continuity between the No. 1 terminal of the A/C condenser fan 2P connector and body ground.
Is there continuity?
YES -
Replace the A/C condenser fan motor.■
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 G202.
