Normal Operation
Under normal operation, the exterior mirror control switch uses circuits CPM16 (BN/BU), CPM17 (BU/GN), CPM23 (GY), CPM20 (BN/WH) or CPM21 (YE/VT) to control the exterior mirror movement.
- When ground is received through circuit CPM16 (BN/BU) or CPM20 (BN/WH) and power through circuit CPM23 (GY), the LH or RH exterior mirror glass will move right.
- When power is received through circuit CPM16 (BN/BU) or CPM20 (BN/WH) and ground through circuit CPM23 (GY), the LH or RH exterior mirror glass will move left.
- When power is received through circuit CPM17 (BU/GN) or CPM21 (YE/VT) and ground through circuit CPM23 (GY), the LH or RH exterior mirror glass will move down.
- When ground is received through circuit CPM17 (BU/GN) or CPM21 (YE/VT) and power through circuit CPM23 (GY), the LH or RH exterior mirror will operate up.

Possible Causes
- Open in circuits CPM16 (BN/BU), CPM17 (BU/GN), CPM20 (BN/WH) or CPM21 (YE/VT)
- Inoperative exterior mirror control switch
- Inoperative exterior mirror motor
