626 LX L4-2.0L DOHC (1999)
Condenser Fan Motor Relay: Testing and Inspection
1. Verify that A/C switch and fan switch are OFF.
2. Start the engine and let it idle.
3. Verify that the condenser fan is not operating.
4. If condenser fan is operating, check:
-
Condenser fan relay for stuck in closed position.
-
Short to power in circuit between condenser fan relay and condenser fan.
-
Short to ground in circuit between A/C pressure switches and PCM.
-
Short to ground circuit between condenser fan relay and PCM terminal 17 (short circuit).
5. Turn the A/C switch and fan switch ON.
6. Verify that the condenser fan is operating and operating sound of A/C compressor magnetic clutch is heard.
7. Turn the A/C switch and fan switch OFF.
8. If the condenser fan does not operate but operating sound of A/C compressor magnetic clutch is heard, check as follows:
-
Open circuit between ignition switch and condenser fan relay.
-
Open circuit between battery and condenser fan relay.
-
Open circuit between condenser fan relay and PCM.
-
Open circuit between condenser fan relay and condenser fan motor or fan motor ground.
-
Condenser fan relay stuck to open.
-
Condenser fan motor.
9. If both condenser fan and A/C compressor do not operate, check:
-
TP V PID.
-
A/C system.
A/C, BLOWER, AND CONDENSER FAN RELAY INSPECTION
1. Remove the relay.
2. Check for continuity between the relay terminals by using an ohmmeter.
If not as specified, replace the relay.
