Mirrors: Description and Operation

POWER MIRROR SYSTEM COMPONENTS
The power mirror system consists of the following components:
^ Outside rearview mirror switch
^ Mirror selector switch
^ Driver outside rearview mirror
^ Passenger outside rearview mirror
^ PWR MIRROR Fuse 1OA

Each of the outside rearview mirrors 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. Each of the outside rearview mirror motors are circuit breaker protected.

POWER MIRROR SYSTEM CONTROLS
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 (L, Off and R).

POWER MIRROR SYSTEM OPERATION
The outside rearview mirror switch receives power through the battery positive voltage circuit from the PWR MIRROR 1OA Fuse. The power mirror switch also receives a constant ground.

The tour 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 depressed, battery positive voltage will be supplied to the left outside rearview mirror vertical motor through the left mirror motor down control circuit and ground through the left mirror motor left control circuit. If the down switch is depressed, battery positive voltage will be supplied to the left outside rearview mirror vertical motor through the left mirror motor left control circuit and ground through the left mirror motor down 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.

HEATED MIRRORS
Battery positive voltage is supplied through the RR DEFOG fuse in the fuse block to the rear window defogger relay. With the ignition in the ON position, ignition 3 voltage is supplied through the DRL/HVAC/TEMP/HTDST fuse in the fuse block to the rear window defogger relay coil. When you depress the rear window defogger switch, the rear window defogger indicator illuminates and grounds the control circuit of the rear window defogger relay. This energizes the rear window defogger relay and allows battery positive voltage to the HEATED MIRROR fuse (10A). The HEATED MIRROR fuse provides battery positive voltage to the heated mirrors.
