Standard Power Mirror
Each Outside Power Mirror has two reversible motors: one to adjust the Mirror view up and down, the other to adjust 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 these control voltages to either the RH or LH Outside Power Mirror.With the switches in the positions shown in the schematic, the LH Outside Power Mirror is moved. When the Mirror Position Switch is moved up, battery voltage from the ORN wire is applied to the YEL wire and the Up-Down Motor in each Outside Power Mirror. The Mirror Position Switch has a path to ground through the LT GRN wire. the Up contacts of the Mirror Position Switch and the BLK (804) wire. The LH Drive Unit runs and turns the mirror up.
If the Outside Power Mirror 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 LH L-R Motor works in a similar manner when the Mirror Position Switch is moved to the LEFT position. The LT BLU wire gets battery voltage and the WHT wire is grounded through the Mirror Select Switch.
The RH Outside Power Mirror works in the same way as the LH Outside Power Mirror when the Mirror Select Switch is moved to the RIGHT position and the Mirror Position Switch is operated.
