Mirrors: Description and Operation

CIRCUIT OPERATION
Each outside mirror has two reversible motors; one to adjust the mirror view Up and Down, the other to adjust the mirror view Right or Left. The driver operates four switches that control the polarity of the voltage to the motors. The Mirror Select Switch directs these control voltages to either the RH or LH Outside Mirror.

When the Mirror Select Switch is moved to the RIGHT position, the control voltages will be directed to the RH outside mirror. When the Mirror Position 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 RH Outside Mirror. The RH Outside Mirror Up-Down Motor, has a path to ground through the LT GRN and LT BLU wires, the Up contacts of the Mirror Position Switch, and the BLK wire. The RH Up-Down Motor runs and turns the mirror up.

If the Mirror Position Switch is pushed to the DOWN position, the same motor receives voltage. Now the polarity is reversed, with the YEL wire grounded. The motor runs in the opposite direction.

The RH Left-Right Motor operates in a similar manner when the Mirror Position Switch is moved to the RIGHT position. The WHT wire gets battery voltage and the LT BLU wire is grounded through the Mirror Position Switch. If the Mirror Position Switch is pushed to the LEFT position, the polarity is reversed and the motor will run in the opposite direction.

The LH Outside Mirror operates similar to the RH Outside Mirror when the Mirror Select Switch is moved to the LH position and the Mirror Position Switch is operated.
