OPERATION

When equipped, the heated mirror system is activated when the rear window defogger (EBL) system is turned on (refer to 8 - ELECTRICAL/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 (refer to 8 - ELECTRICAL/HEATED GLASS - DIAGNOSIS AND TESTING). If only one outside mirror heating grid is inoperative, most likely the concern lies with the mirror itself (refer to 8 - ELECTRICAL/POWER MIRRORS - DIAGNOSIS AND TESTING).

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 (refer to 23 - BODY/EXTERIOR/SIDE VIEW MIRROR - REMOVAL).
