Mirrors: Testing and Inspection

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 (Refer to POWER MIRRORS/POWER MIRROR SWITCH - REMOVAL).
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 5 in the harness connector at the mirror switch. Touch the test light probe to Pin 3.

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

If the lamp does not illuminate, first check fuse 25 in the Junction Block (JB). If fuse 25 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.

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.

3. Using two jumper wires:
- Connect one to a 12 volt source
- Connect the other to a good body ground
