System Operation

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

The direction switch has two triplets of switch contacts. Each set of 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 left position and the up direction contacts are closed, battery positive voltage will be supplied to both vertical power mirror motors through the left mirror motor up control circuit and the right mirror motor up control circuit. The return path is completed only for the left mirror through the left mirror motor left control circuit, through the select switch and direction switch to ground. The mirror will move up.

If the down direction contacts are closed, battery positive voltage will be supplied through the select switch to both left mirror motors through the left mirror motor left control circuit. The return path is completed only for the left mirror vertical motor through the left mirror motor up 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.
