FULL-AUTOMATIC AIR CONDITIONER – Troubleshooting55-50
Inspection procedure 13
Condenser fan does not operate.
Probable cause
If the condenser fan does not turn when the A/C is ON, the cause is probably
a malfunction of the condenser fan motor activation circuit. In this case, reduced
cooling performance will be caused if the vehicle is not running.Malfunction of condenser fan motor
Malfunction of condenser fan motor relay (HI, LO)
Malfunction of wiring harness or connector
NG
Repair OK
Check the trouble symptom.
NG
Check the harness between the condenser fan motor relay (LO)
and the condenser fan motor, and repair if necessary.
