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

When the mirror control 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 control switch is moved to the LEFT position, battery voltage is applied through the left contacts of the mirror select switch and the left contacts of the mirror control switch to battery to the left-right motor in the LH outside mirror. The LH outside mirror left-right motor is grounded through the left-right contact of the mirror control switch. The LH outside mirror left-right motor runs and turns the mirror to the left.

If the mirror control 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 RH position and the mirror control switch is operated.
