Normal Operation
The exterior mirror control switch is powered from circuit 29-AD12 (OG/YE) and grounds through circuit 31-AD12 (BK/YE). The exterior mirror control switch activates the LH exterior mirror by switching power and ground to circuits 32-AD32 (WH/RD), 34-AD31 (BU/WH) and 33-AD7 (YE/RD) and activates the RH exterior mirror by switching power and ground to circuits 32-AD30 (WH/BK), 34-AD29 (BU/OG) and 33-AD10 (YE/BK). The exterior mirror control switch must be in the appropriate (left or right) position for the desired mirror to operate.

Possible Causes
