Mirrors: Description and Operation

CIRCUIT 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 four switches that control the polarity of the voltage to the motors. The Mirror Select Switch directs the voltage to either the RH or LH Outside Mirror.

When the LH Outside Mirror is selected and the "UP" position of the switch is pressed, 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 Switch has a path to ground through the LT ORN wire, the Up contacts of the switch and the BLK wire. The LH Motor runs and turns the mirror up.

If the Mirror Control Switch is pressed in 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 Left/Right Motor operates in a similar manner. When the "L" Switch is pressed, the WHT wire receives battery voltage and the LT GRN wire is grounded through the switch. The motor runs and moves the mirror left. When the "R" Switch is pressed, the motor receives battery voltage through the LT GRN wire and ground through the WHT wire. The motor runs in the opposite direction to move the mirror right.

The RH Outside Mirror works the same way as the LH Outside Mirror when the Mirror Select Switch is moved to the "RH" position and the appropriate position switch is operated.
