Normal Operation
Under normal operation the exterior mirror control switch uses circuit 33-AD8 (YE/BU) to control the LH exterior mirror left/right movement, circuit 34-AD7 (BU/RD) to control the LH exterior mirror up/down movement, circuit 32-AD6 (WH) as a common circuit to control the LH exterior mirror up/down and left right movement, circuit 33-AD11 (YE/VT) to control the RH exterior mirror left/right movement, circuit 34-AD10 (BU/YE) to control the RH exterior mirror up/down movement, and circuit 32-AD9 (WH/GN) as a common circuit to control the RH exterior mirror up/down and left right movement. Each circuit is a switched voltage/ground circuit based upon the exterior mirror control switch position.

Possible Causes
- circuit 33-AD8 (YE/BU) open, short to voltage, or short to ground
- circuit 34-AD7 (BU/RD) open, short to voltage, or short to ground
- circuit 33-AD11 (YE/VT) open, short to voltage, or short to ground
- circuit 34-AD10 (BU/YE) open, short to voltage, or short to ground
- exterior mirror control switch
