Heated Glass Element Relay: Description and Operation
DESCRIPTION
CAUTION: Grid lines can be damaged or scraped off with sharp instruments. Care should be taken in cleaning glass or removing foreign materials,
decals or stickers. Normal glass cleaning solvents or hot water used with rags or toweling is recommended.
The rear window defogger system, also known as electric backlight (EBL), consists of two vertical bus bars linked by a series of grid lines fired onto
the inside surface of the rear window.
The EBL system is turned On or Off by a switch in the A/C-heater control located at the center of the instrument panel and by a rear window defogger
timing circuit integral to the front control module (ECM).
Circuit protection is provided by a 40 amp fuse located in the integrated power module (IPM). See: Power and Ground Distribution
