Power Mirrors Test

WIRING VOLTAGE TEST
The following wiring test determines whether or not voltage is continuous through the body harness to switch.
1. Remove the power mirror switch.
2. Disconnect wire harness connector from back of power mirror switch.
3. Connect the clip end of a 12 volt test light to Pin 11 in the mirror switch harness connector. Touch the test light probe to Pin 9.

If the test light illuminates, the wiring circuit between the battery and switch is OK.

If the lamp does not illuminate, first check fuse in the Junction Block (JB). If circuit breaker is OK, then check for a broken wire.

Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

SIDE REPEATER LAMP TEST
Some vehicles are equipped with side repeater lamps integral to the sideview mirror. If the LED's within the mirror do not operate and the other within the system do, proceed with the side repeater lamp test. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

1. Remove the door trim panel (Refer to BODY/DOOR - FRONT/TRIM PANEL - REMOVAL).
2. Disconnect wire harness connector from mirror.
3. Turn the ignition to the ON position and actuate the turn signal on the appropriate side.
4. Using a 12-volt test light, check for voltage at pin 12 (left side) or pin 8 (right side) while turn signals are functioning.
5. Check for ground at pin 1.

If the test light does not illuminate, check for a broken or shorted wire.

If the test light illuminates, the wiring circuit between the turn signal switch and the mirror wire harness connector is OK. Replace the mirror assembly

POWER MIRROR MOTOR TEST
If the power mirror switch is receiving proper current and ground and mirrors do not operate, proceed with power mirror motor test. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
1. Remove the power mirror switch.

2. Disconnect wire harness connector to power mirror switch.
3. Using two jumper wires:
- Connect one to a 12 volt source
- Connect the other to a good body ground
- Refer to the Mirror Motor Test Chart for proper wire connections at the switch connector
