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 LH 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 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 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 RH position and the UP-DOWN and LEFT-RIGHT switches are operated.
