The power mirror switch incorporates a mirror select switch and a four position mirror direction switch.
The mirror select switch allows the operator to select the mirror to be moved by rotating counterclockwise to the L position (left outside power mirror) or rotating clockwise to the R position (right outside power mirror).
The mirror direction switch is a four position switch that allows the operator to move the selected mirror up, down, left or right.
The heated mirror system is activated by depressing the rear window defogger switch, which is part of the HVAC control module. For further information on the rear window defogger operation, refer to Rear Window Defogger Circuit Description in Stationary Windows.
The automatic day -- night mirror system changes the reflectiveness of the inside and outside rear view mirrors. This is done to reduce the amount of glare given off by the mirrors when headlamps are approaching from the rear during low light conditions.
