Normal Operation
The exterior mirror control switch receives power from circuit 956 (OG/LG) and ground from circuit 1205 (BK). The exterior mirror control switch controls the LH exterior mirror by switching power and ground to circuits 942 (RD/OG), 940 (DB/OG) and 945 (YE/BK) and for the RH exterior mirror by switching power and ground to circuits 944 (DG/OG), 943 (VT/OG) and 945 (YE/BK).
Possible Causes
- circuit 956 (OG/LG) open
- circuit 1205 (BK) open
- circuit 940 (DB/OG) short to ground
- circuit 942 (RD/OG) short to ground
- circuit 943 (VT/OG) short to ground
- circuit 944 (DG/OG) short to ground
- circuit 945 (YE/BK) short to ground
