Test A: The Mirrors Are Inoperative

PINPOINT TEST A: THE MIRRORS ARE INOPERATIVE

A1-A3:

A3-A4:

Normal Operation
Under normal operation the exterior mirror control switch receives voltage through circuit 29-AD12 (OG/YE) and ground through circuit 31-AD12 (BK). The exterior mirror control switch uses circuit 32-AD1 (WH/RD) 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
- circuit 29-AD12 (OG/YE) open
- circuit 31-AD12 (BK) open
- circuit 32-AD1 (WH/RD) open, short to ground, or short to voltage
- exterior mirror control switch
