Heated Glass Element Switch: Description and Operation
Operation
OPERATION
An amber indicator in the rear window defogger switch will illuminate when the rear window defogger switch is activated. When the rear window
defogger switch is pressed to ON, the body control module (BCM) energizes the rear window defogger (EBL) relay. When the relay is energized, fused
battery current is directed through the relay to the rear window defogger grid lines and the heated outside rear view mirrors, when equipped. The grid
lines heat the glass to help clear the rear windows and outside mirror surfaces of fog or frost.
NOTE: The EBL system turns off automatically after approximately 10 minutes of initial operation. Each following activation cycle of the EBL
system will last approximately 5 minutes.
The EBL system will be automatically turned off after an initial programmed time interval of about 10 minutes as long as the ignition switch is in RUN.
After the initial time interval has expired, if the rear window defogger switch is pressed to ON again during the same ignition cycle, the EBL system will
automatically turn off after about 5 minutes. The EBL system will also turn off if the ignition switch is turned to any position other than RUN or by
manually pressing the rear window defogger switch a second time.
The rear window defogger switch and indicator lamp cannot be adjusted or repaired and the A/C-heater control must be replaced if inoperative or
damaged.
