Heated Mirrors - Operation
OPERATION
When equipped, the heated mirror system is activated when the rear window defogger (EBL) system is turned on Heated Glass - Operation. When the heated mirror system is activated, an electric grid located behind the glass of each outside rear view mirror becomes energized and produces heat to help clear the mirror of ice, snow, or fog.
If both outside mirror heating grids are inoperative, test the EBL system for proper operation Testing and Inspection. If only one outside mirror heating grid is inoperative, most likely the concern lies with the mirror itself Testing and Inspection.
The heating grid behind the outside rear view mirror glass cannot be repaired and the mirror assembly must be replaced if the heating grid is found to be inoperative Outside Rearview Mirror - Removal.
