Mirrors: Description and Operation

How the Circuit Works

The two outside mirrors are controlled by the power mirror switch. Each mirror has two reversible motors: one motor moves the mirror up and down and the other motor moves the mirror left and right.

The power mirror switch contains four switches to control mirror adjustment, and a switch to select the left or right mirror. With the ignition ON (II), battery voltage is supplied to the power mirror switch. The mirror selector switch directs voltage from the direction switches to either the left or right mirror.

Mirror Up

When you press the "up" edge of the mirror adjustment button, voltage is supplied from one of the UP switch contacts to both mirrors. With the mirror select switch in the LEFT or RIGHT position, ground is provided for the corresponding up/down motor through the opposite UP switch contact. Battery voltage is supplied to the mirror up/down motor which then tilts the selected mirror up.

Mirror Down

When you press the "down" edge of the mirror adjustment button, ground is provided through one of the DOWN switch contacts to both mirrors With the mirror select switch in the LEFT or RIGHT position, voltage is supplied to the corresponding up/down motor through the opposite DOWN switch contact. Battery voltage is supplied to the mirror up/down motor which then tilts the selected mirror down

Mirror Left

When the mirror select switch is in the LEFT or RIGHT position, and you press the "left" edge of the mirror adjustment button, voltage is supplied to both corresponding mirror motors through one of the LEFT switch contacts. Ground is provided for the corresponding left/right motor through the opposite LEFT switch contact. Battery voltage is supplied to the mirror left/right motor which then tilts the selected mirror left.

Mirror Right

When the mirror select switch is in the LEFT or RIGHT position, and you press the "right" edge of the mirror adjustment button, ground is provided to both corresponding mirror motors through one of the RIGHT switch contacts. Voltage is supplied to the corresponding left/right motor through the opposite RIGHT switch contact. Battery voltage is supplied to the mirror left/right motor which then tilts the selected mirror right.

Mirror Defoggers (Canada)

With the ignition switch in ON (II), battery voltage is supplied to the mirror defogger switch. When you press the mirror defogger switch ON, voltage is supplied to both mirror defoggers, causing them to heat up and remove any fog from the mirrors. The opposite side of each defogger grid is connected to ground.
