Power Mirror System Chevrolet Chevy Van G2500

DESCRIPTION & OPERATION

Power mirror assemblies contain 2 motors each. One motor positions the mirror up and down, and the other positions mirror right and left. Reversing polarity of motors will move power mirrors in opposite directions. The power mirror switch is located on the left door trim panel.

TROUBLE SHOOTING

Before proceeding with specific testing, check the following for proper operation

1. Check courtesy light and CTSY (15-amp or 20-amp) fuse for proper operation.
2. Check power seat system operation. Ensure power accessory circuit breaker is okay.
3. Check and ensure grounds are clean and tight.
4. Check for broken or partially broken wire inside insulation, which could cause system malfunction, but prove good in a continuity/voltage check with system disconnected. These circuits may be intermittent or have high resistance when loaded, and if possible, should be checked by monitoring voltage drop with system operational (under load).
5. Check for proper installation of aftermarket electronic equipment.

TESTING

Note. In the following tests, use a self-powered test light unless otherwise specified.

BOTH POWER MIRRORS DO NOT OPERATE

1. Disconnect power mirror switch connector. Connect test light between power mirror switch harness connector terminal "E" (Orange wire) and ground. If test light illuminates, go to next step. If test light does not illuminate, repair open in Orange wire between power mirror switch and instrument panel fuse block.
2. Connect DVOM between power mirror switch harness connector terminal "D" (Black wire) and ground. If test light illuminates, check for poor connection at power mirror switch connector. If connection is okay, replace power mirror switch. If test light does not illuminate, repair poor connection or open in Black wire between power mirror switch and ground.
