System Testing
NOTE:
Key must be in ignition for power mirrors to operate.
NOTE:
If both mirrors are inoperative, begin testing at step 1). If one mirror is inoperative, remove switch panel assembly (instrument cluster cover), insert key into ignition and begin testing at step 6).
- Turn ignition on. Check ROOM fuse. If fuse is okay, go to next step. If fuse is blown, replace fuse (repair wiring if necessary).
- Remove switch panel assembly (instrument cluster cover). Check voltage at Pink/Black wire terminal of power mirror switch connector. If battery voltage is present, go to step 5). If battery voltage is not present, go to next step.
- Remove steering column cover. Check voltage at Blue/Red wire terminal of key reminder switch connector. If battery voltage is present, go to next step. If battery voltage is not present, repair Blue/Red wire between fuse and key reminder switch.
- Check voltage at Blue/Red wire terminal of key reminder switch connector. With key inserted, battery voltage should be present. With key removed, zero volts should be present. If voltage is as specified, repair wiring between key reminder switch and power mirror switch. If voltage is not as specified, replace key reminder switch.
- Disconnect power mirror switch connector. Check continuity between ground and Black wire terminal of power mirror switch connector. If there is continuity, reconnect power mirror switch connector and go to next step. If there is no continuity, repair Black wire.
- Check voltage at the following terminals of power mirror switch connector with switch in specified position. If battery voltage is not present at all terminals, replace power mirror switch. If battery voltage is present at all terminals, go to next step.
- Brown wire (right mirror UP)
- Green/Yellow wire (right mirror DOWN)
- Green/Yellow wire (right mirror LEFT)
- Green/White wire (right mirror RIGHT)
- Brown wire (left mirror UP)
- Blue/Yellow wire (left mirror DOWN)
- Blue/Yellow wire (left mirror LEFT)
- Brown/Yellow wire (left mirror RIGHT).
- At power mirror motor connector, check voltage at terminals specified in previous step with switch in specified position. If battery voltage is not present at all terminals, repair wiring between power mirror switch and power mirror motor. If battery voltage is present at all terminals, replace power mirror motor.
