Mirrors: Description and Operation
HEATED MIRRORSElectrically heated outside rear view mirrors are optional equipment on this model. Heated mirrors are available with Memory Mirrors and Rear Window Defogger only. These mirrors feature an electric heating grid located behind the mirror glass of each power operated outside rear view mirror. These heating grids consist of a single resistor wire routed in a grid-like pattern and captured between two thin sheets of plastic. When electrical current is passed through the resistor wire, it produces enough heat energy to clear the outside mirror glass of ice, snow or fog. Battery current is directed to the outside mirror heating grid only when the rear window defogger switch is in the On position.
If the outside mirror heating grids and the rear window heating grid are all inoperative. If the outside mirror heating grids are inoperative, but the rear window heating grid is operating as designed, for diagnosis of the outside mirror heating grids.
The heating grid behind each outside mirror glass cannot be repaired and, if faulty or damaged, the entire power mirror unit must be replaced. Refer to Power Mirrors for the procedures.
