DESCRIPTION & OPERATION

CAUTIONWhen battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.

Voltage is supplied to the Power Mirror Switch at all times through the HORN/DM Fuse and the ORN (140) wire. Ground is provided through the BLK (150) wire and the Busbar Ground. See WIRING DIAGRAMS .

Rotating the Power Mirror Switch fully clockwise allows for control of the right mirror. Rotating the switch fully counter-clockwise allows for control of the left mirror.

With the switch set for the left mirror, moving the switch handle to the left, connects the LT BLU (82) wire to the BLK (150) wire and the WHT (81) wire to the ORN (140) wire. The mirror will then move to the left, moving the switch handle to the right reverses polarity to the mirror motor and the mirror moves to the right.

Moving the switch handle up connects the LT BLU (82) wire to the ORN (140) and the YEL (88) wire to the BLK (150) wire. The mirror will then move up, moving the switch handle down reverses the polarity to the motor and the mirror moves down.

PRELIMINARY INSPECTION

Verify customer complaint by operating suspected system. Visually inspect for obvious signs of mechanical and electrical damage. Inspect for blown fuses and damaged relays. For fuse and/or relay identification, refer to illustrations. See WIRING DIAGRAMS . Inspect for loose or corroded connections, damaged wiring harnesses and/or switches. Check for a broken or partially broken wire inside insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. Ensure any aftermarket electronic equipment is properly installed. If fault is found, repair as necessary.
