Normal Operation
Under normal operation, the exterior mirror control switch receives power through circuit SBP12 (WH/OG) and ground through circuit GD133 (BK). The exterior mirror control switch uses circuit CPM23 (GY) as the common circuit for both exterior mirror up/down and right/left movement.

Possible Causes
- Open in circuits SBP12 (WH/OG) or GD133 (BK)
- Open, short to ground or short to power in circuit CPM23 (GY)
- Inoperative exterior mirror control switch
- Fuse
