System Operation

The power mirror switch receives power through the battery positive voltage circuit from the PWR MIRROR Fuse 10 A. The power mirror switch also receives a constant ground.

The direction switch has multiple switch contacts. Each of the contacts are connected to opposing sides of the appropriate power mirror motors. One side of each motor is connected through the select switch. The select switch interrupts or completes these circuits depending on the position of the select switch.

If the select switch is placed in the L position and the up switch is depressed, battery positive voltage will be supplied to all four power mirror motors through the left mirror motor left control circuit and the right mirror motor left control circuit. The return path is completed only for the left mirror through the left mirror motor down control circuit, through the select switch and direction switch to ground. The mirror will move up.

If the down switch is depressed, battery positive voltage will be supplied to the left mirror vertical motor through the select switch and the left mirror motor down control circuit. The return path is completed through the left mirror motor left control circuit, through the direction switch to ground. The mirror will move down.

The remainder of the mirror functions operate in a similar manner as described above. Pressing the power mirror switch in opposing positions will reverse the polarity to the selected mirror motor, utilizing the same circuits and the power mirror will move in the opposite direction.
