System Testing

Turn ignition on. Check RADIO fuse. If fuse is blown, replace fuse (repair wiring if necessary). If fuse is okay, check 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 there is no continuity, repair Black wire.
If there is continuity, check power mirror switch. See POWER MIRROR SWITCH under COMPONENT TESTING. If power mirror switch is okay, reconnect power mirror switch connector. Disconnect power mirror motor connector.
With power mirror switch in specified position, check voltage at specified terminals of power mirror motor connector. See POWER MIRROR CIRCUIT TEST table. If battery voltage is present, replace power mirror motor. If battery voltage is not present, repair wiring between power mirror switch and power mirror motor.
