Circuit Testing

Turn ignition on. Check RADIO 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, check power mirror switch. See POWER MIRROR SWITCH TEST under COMPONENT TESTING. Replace power mirror switch if faulty. If power mirror switch is okay, reconnect power mirror switch connector. Disconnect power mirror motor connector.
Measure voltages at power mirror motor connector terminals with power mirror switch in specified position. See POWER MIRROR CIRCUIT TEST table. 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.
