System Testing
NOTE:
If both mirrors are inoperative, begin testing at step 1). If one mirror is inoperative, begin testing at step 3).
- Turn ignition on. Check CIGAR fuse. If fuse is blown, replace fuse (repair wiring if necessary). If fuse is okay, measure voltage at Blue/Black wire terminal of power mirror switch connector. If battery voltage is not present, repair Blue/Black wire between fuse and power mirror switch.
- If battery voltage is present, disconnect power mirror switch connector. Check continuity between ground and Black wire terminal of power mirror switch connector. If continuity does not exist, repair Black wire between power mirror switch and ground. If continuity exists, reconnect power mirror switch connector.
- Measure 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)
- Light Green/Red wire (right mirror DOWN)
- Light Green/Red wire (right mirror LEFT)
- Brown/Black wire (right mirror RIGHT)
- Brown wire (left mirror UP)
- Light Green wire (left mirror DOWN)
- Light Green wire (left mirror LEFT)
- Brown/Yellow wire (left mirror RIGHT).
- Measure voltages at power mirror motor connector terminals as specified in previous step with power mirror 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 assembly.
