Mirrors: Description and Operation

Each outside mirror has two reversible motors. One adjusts the mirror view up and down and the other adjusts the mirror view right and left. The driver operates a switch that controls the polarity of the voltage to the motors. The mirror select switch directs the voltage to either the RH or LH outside mirror.

When the LH outside mirror is selected and the outside remote control rearview mirror switch is in the UP position, battery voltage from circuit 1140 is applied to circuit 88 and the up/down motor in the LH outside mirror. The outside remote control rearview mirror switch supplies a path to ground through circuit 1499, the up contacts of the switch and circuit 750. The LH up/down motor runs and turns the mirror up.

If the outside remote control rearview mirror switch is in the DOWN position, the same motor receives voltage from circuit 1499, while circuit 88 supplies ground. The motor then runs in the opposite direction.

The right/left motor operates in a similar manner. When the outside remote control rearview mirror switch is in the LEFT position, circuit 1499 receives battery voltage and circuit 81 is grounded through the switch. The motor runs and moves the mirror left. When the RIGHT switch is pressed, the motor receives battery voltage through circuit 81 and ground through the circuit 1499. The motor runs in the opposite direction to move the mirror right.

The RH outside mirror works in a similar way as the LH outside mirror when the mirror select switch is moved to the RH position and the appropriate position switch is operated.
