POWER MIRRORS - SERVICE INFO
DESCRIPTION
The power operated sideview mirrors allow the driver to adjust both outside mirrors electrically from the drivers seat by operating a switch (3) on the driver side front door trim panel (1).
OPERATION
The power mirrors receive ignition current through a fuse in the junction block, and will only operate when the ignition switch is in the Run position.
DIAGNOSIS AND TESTING - POWER MIRRORS
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 8 - ELECTRICAL/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.
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.
1. Remove front door trim panel to gain access to power mirror wire connector (Refer to 23 - BODY/DOOR - FRONT/TRIM PANEL - REMOVAL).
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
