Normal Operation
Under normal operation, the exterior mirror control switch receives power from circuit SBP12 (WH/OG) and ground from circuit GD133 (BK). The exterior mirror control switch sends input to the driver seat module (DSM) for the LH exterior mirror by switching power and ground to circuits CPM16 (BN/BU), CPM17 (BU/GN) and CPM23 (GY); and for the RH exterior mirror by switching power and ground to circuits CPM20 (BN/WH), CPM21 (YE/VT) and CPM23 (GY). The DSM will then send the appropriate power and ground for the LH exterior mirror motor down/up circuits CPM29 (GN), CPM26 (WH) and right/left circuits CPM28 (BU/BN) and CPM27 (GY/BU); or the RH exterior mirror motor down/up circuits CPM34 (WH/BN), CPM31 (YE/GY) and right/left circuits CPM32 (WH/BU) and CPM33 (WH/VT).

Possible Causes
- An open, short to voltage or short to ground in circuits: CPM21 (YE/VT), CPM16 (BN/BU), CPM23 (GY), CPM20 (BN/WH), CPM17 (BU/GN), CPM32 (WH/BU), CPM33 (WH/VT), CPM34 (WH/BN), CPM31 (YE/GY), CPM27 (GY/BU), CPM28 (BU/BN), CPM29 (GN) or CPM26 (WH)
- Open in circuit SBP12 (WH/OG)
- Open in circuit GD133 (BK)
- Inoperative DSM
- Inoperative exterior mirror control switch
- Inoperative exterior mirror
