Outside Mirror Description and Operation

The power mirror system consists of the following components:

Each of the outside rearview mirror contains two motors. The vertical motor operates the mirror in the up and down directions, and the horizontal motor operates the mirror in the left and right directions.

The outside rearview mirror switch is a four position directional switch: Up, Down, Left and Right.

The mirror select switch is a three position switch: left, neutral/fold, and right.

The outside rearview mirror switch receives battery voltage from the underbonnet fuse block The power mirror switch also receives a constant ground.

The four positions of the direction switch have dual switch contacts. Each of the contacts are connected to opposing sides of the appropriate power mirror motors through the selector switch. The selector switch completes these circuits depending on the position of the selector switch, L or R.

If the selector switch is placed in the L position and the up switch is pressed, battery voltage will be supplied to the left outside rearview mirror vertical motor through the left mirror motor vertical control circuit and ground through the left mirror motor common control circuit. If the down switch is pressed, battery voltage will be supplied to the left outside rearview mirror vertical motor through the left mirror motor common control circuit and ground through the left mirror motor vertical control circuit.

The remainder of the mirror functions operate in the same manner as described above. Placing the power mirror switch in opposing positions, left/right or up/down, will reverse the polarity to the mirror motor, reversing the direction of movement.

The folding mirror system is controlled through an electronic switch that can be activated when the mirror select switch is in the neutral position. When the mirror select switch is in the neutral position, the fold/retract function is activated by pressing the down arrow. The fold/retract switch will fold or retract the mirrors depending on their current state. When a power fold or retract function is activated, battery voltage is supplied to the fold motor by the appropriate fold or retract control circuit and the motor will be grounded by the opposite control circuit.

The heated mirrors are controlled through the rear demist relay. Whenever the rear window demister is turned on battery voltage is supplied to the mirror heater elements through the left and right mirror heater element control circuits.
