Normal Operation
The exterior mirror control switch receives power through circuit SBP12 (GN/RD) and ground through circuit GD143 (BK/VT). 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
- Fuse
- An open in circuits CPM23 (GY), SBP12 (GN/RD) or GD143 (BK/VT)
- A short to ground in circuit CPM23 (GY)
- A short to voltage in circuit CPM23 (GY)
- Exterior mirror control switch
