Power Mirrors Test

WIRING VOLTAGE TEST
The following wiring test determines whether or not voltage is continuous through the body harness to switch.

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 connector from back of power mirror switch.
3. Switch ignition to the RUN position.
4. Connect the clip end of a 12 volt test light to Pin 4 in the harness connector at the mirror switch. Touch the test light probe to Pin 3, then Pin 10.

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

If the lamp does not illuminate, first check fuse 7 and fuse 1 in the Fuse Block. If fuses are OK, then check for broken wire(s).

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 front door trim panel to gain access to power mirror wire connector.
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.
