Mirrors: Description and Operation

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 three switches to control mirror direction, and two switches to select the left or right mirror. With the ignition switch in ON (II), battery voltage is supplied to the power mirror switch. The mirror selector switch directs voltage from two of the direction switches to either the left or the right mirror. Each direction switch is used for more than one function.

Mirror Up
With the power mirror switch in the up position, switch 1 is moved to the A position. Switch 1 applies battery voltage to both the left and right power mirror up/down motors. If the mirror selector switch is in the left position, the left up/down motor is grounded through the mirror selector switch and switch 2 in the B position to G401. If the right mirror up/down motor is selected, it is also grounded through switch 2 in the B position.

Mirror Down
With the power mirror switch in the down position, switches 2 and 3 are moved to the A position. Switch 2 applies battery voltage to the left or right power mirror up/down motor as determined by the mirror selector switch. The selected mirror motor is grounded through switch 1 in the B position to G401. When switch 2 is moved to position A, it also applies battery voltage to the selected mirror left/right motor. With switch 3 in the A position, battery voltage is supplied to both sides of the left/right motor so it does not move.

Mirror Left
With the power mirror switch in the left position, switches 1 and 2 are moved to the A position. Switch 2 applies battery voltage to the left or right power mirror left/right motor as determined by the mirror selector switch. The selected mirror motor is grounded through switch 3 in the B position to G401. When switch 2 is moved to position A, it also applies battery voltage to the selected mirror up/down motor. With switch 1 in the A position, battery voltage is supplied to both sides of the up/down motor so it does not move.

Mirror Right
With the power mirror switch in the right position, switch 3 is moved to the A position. Switch 3 applies battery voltage through the mirror selector switch to the left or right left/right motor. The motor is grounded through the mirror selector switch and switch 2 in the B position to G401.

Mirror Defogger
With the ignition switch in ON (II), battery voltage is supplied to the mirror defogger switch in the power mirror switch.

When the mirror defogger switch is in the ON position, voltage is supplied through the ORN wires to defoggers in the power mirrors. The defogger coils are then energized by the BLK wires going to G401.

The defogger remain ON as long as the mirror defogger switch and the ignition switch are both in the ON position.
