Normal Operation
The exterior mirror control switch receives voltage from circuit 29-AD12 (OG/YE) and ground from circuit 31-AD12 (BK/YE). The exterior mirror control switch sends input to the driver door module (DDM) for the LH exterior mirror by switching voltage and ground to circuits 32-AD32 (WH/RD), 34-AD31 (BU/WH) and 33-AD12 (YE) and for the RH exterior mirror by switching voltage and ground to circuits 32-AD30 (WH/BK), 34-AD29 (BU/OG) and 33-AD12 (YE). The DDM then sends the appropriate voltage and ground for the LH exterior mirror motor up/down circuits 34-AD8 (BU/WH), 35-AD8 (VT) and left/right circuits 32-AD7 (WH/RD) and 33-AD7 (YE/RD). The DDM sends a message to the front electronic module (FEM) over the standard corporate protocol (SCP) communication link for the FEM to send the appropriate voltage and ground for the RH exterior mirror motor up/down circuits 34-AD11 (BU/OG), 35-AD11 (VT/WH) and left/right circuits 32-AD10 (WH/BK), 33-AD10 (YE/BK).

Possible Causes
- circuit 29-AD12 (OG/YE) open or short to ground
- circuit 33-AD12 (YE) open, short to ground or power
- circuit 31-AD12 (BK/YE) open or short to power
- DDM
- exterior mirror control switch
- exterior mirror motors
