Heated Glass Element Switch: Description and Operation
Description
DESCRIPTION
The switch for the rear window defogger (EBL) system (1) is integral to the blower speed control located on the A/C-heater control (2) in the instrument
panel. When the rear window defogger switch is pressed to the On position, a request signal is sent over the CAN-IHS bus to the totally integrated power
module (TIPM) to operate the EBL system and the amber indicator (3) illuminates.
When the EBL relay is energized, current is directed to the rear defogger grid lines and to the heated side view mirrors, when equipped. The grid lines
heat the glass to help clear the rear window and side mirror surfaces of fog or frost.
