Heated Glass Element Switch: Description and Operation
Rear Defogger Switch - Description
DESCRIPTION
The switch for the rear window defogger system (2), also know as the Electric Backlight (EBL), is integrated into the A/C-heater control (1), located in
the center of the instrument panel. When the rear window defogger switch is activated, the timing circuit integral to the A/C-heater control operates the
rear window defogger (EBL) relay. An amber indicator (3) in the rear window defogger switch will illuminate to indicate when the EBL system is turned
on.
When the EBL relay is activated, current is directed to the rear window defogger grid lines and to the heated outside rear view mirrors (when equipped),
to heat the glass and help clear the rear window and outside mirror surfaces of fog or frost.
