Each mirror contains 2 reversible motors, one for horizontal movement and the other for vertical movement. Power mirror switch on driver's door controls power and ground circuits of power mirror motors. Power mirror switch has a selector switch and a perimeter switch. Position of selector switch determines whether left or right mirror is controlled by switch. Perimeter switch controls vertical and horizontal movements of selected mirror.

TROUBLE SHOOTING

If both mirrors are inoperative, begin testing at step 1). If one mirror is inoperative, begin testing at step 4).

1. Turn ignition on. Check CIGAR fuse (15-amp). If fuse is blown, replace fuse (repair wiring if necessary). If fuse is okay, go to next step.
2. Measure voltage at Blue/Black wire terminal of power mirror switch connector. If battery voltage exists, go to next step. If battery voltage does not exist, repair Blue/Black wire between fuse and power mirror switch.
3. Disconnect power mirror switch connector. Check continuity between ground and Black wire terminal of power mirror switch connector. If continuity exists, reconnect power mirror switch connector and go to next step. If continuity does not exist, repair Black wire between power mirror switch and ground.
4. Measure voltage at the indicated power mirror switch connector terminals with switch in specified position. If battery voltage exists at all terminals, go to next step. If battery voltage does not exist at all terminals, replace power mirror switch.
5. Measure voltages at power mirror motor connector terminals as specified in previous step with power mirror switch in specified position. If battery voltage does not exist at all terminals, repair wiring between power mirror switch and power mirror motor. If battery voltage exists at all terminals, replace power mirror assembly.

BOTH MIRRORS INOPERATIVE

Check fuse. Check power and ground circuits of power mirror switch. Check power mirror switch. Check wiring between power mirror switch and power mirror motors.

ONE MIRROR INOPERATIVE

Check power mirror motor. Check wiring between power mirror switch and power mirror motor. Check power mirror switch.
