Circuit Operation

The power mirrors are adjusted from the interior of the vehicle by moving the outside mirror control switch in the desired direction

Each outside mirror has two reversible motors. One adjusts the mirror view up and down, the other adjusts the mirror view right and left. The driver operates the UP-DOWN/LEFT-RIGHT switch to control the polarity of the voltage motors. The mirror select switch directs these control voltages to either the RH or LH outside mirror.

With the mirror select switch in the "L" position and the mirror position switch held in the "UP" position, battery voltage is applied through the "UP" contacts of the mirror position switch to the updown motor in the LH outside mirror. The LH outside mirror updown motor has a path to ground through the mirror select switch and the DOWN contact of the mirror position switch to ground. The LH outside mirror up-down motor runs and turns the mirror up.

When the mirror position switch is pushed to the "DOWN" position. the LH outside mirror UP-DOWN motor receives voltage; however, voltage polarity is reversed. The motor runs in the opposite direction.

The LH outside mirror left-right motor operates similarly. When the mirror position switch is moved to the "LEFT" position, battery voltage is applied through the LEFT-RIGHT motor in the LH outside mirror. The LH outside mirror has a path to ground through the mirror select switch and the RH contact of the mirror position switch to ground. The LH outside mirror left-right motor runs and turns the mirror to the left.

If the LEFT-RIGHT switch is pushed to the "RIGHT" position, the same motor receives voltage; however, voltage polarity is reversed. The motor runs in the opposite direction.

The RH outside mirror works the same way as the LH outside mirror when the mirror select switch is moved to the "R" position and the UP-DOWN and LEFT-RIGHT switches are operated.
