A4:

Normal Operation
The exterior mirror control switch receives voltage through circuit 543 (DG) and ground through circuit 57 (BK). The exterior mirror control switch uses circuit 542 (YE) as the common circuit for both exterior mirror up/down and right/left movement and is a common switched ground/voltage circuit based upon the mirror control switch position.

Possible Causes
- fuse
- circuit 57 (BK) open
- circuit 542 (YE) open
- circuit 543 (DG) open
- exterior mirror control switch
