Mirrors: Description and Operation

Each outside Mirror has two reversible motors. One adjusts the mirror view up and down and the other adjusts the mirror view right and left. The driver operates the Outside Mirror Switch, a joystick type switch, that controls the polarity of the voltage to the motors. This switch also directs the voltage to either the RH or LH Outside Mirror.
With the switches in the positions shown in the schematic, the LH Outside Mirror is selected. When the Outside Mirror Switch is moved to the "UP" position, battery voltage from the ORN wire is applied to the YEL wire and the Up/Down Motor in the LH Outside Mirror. The LH Outside Mirror Up/Down Motor has a path to ground through the LT GRN wire, the Up contacts of the Outside Switch and the BLK wire. The LH Motor runs and turns the mirror up.
If the Outside Mirror Switch is moved to the "DOWN" position, the same motor receives voltage from the LT GRN wire, while the YEL wire is grounded. The motor runs in the opposite direction.
The LH Left/Right Motor operates in a similar manner with the Outside Mirror Switch in the "LEFT" position.
