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 (1) linked by a series of grid lines (2) fired onto the inside surface of the rear window (3).
The EBL system is turned On or Off by a switch and timing circuit integral to the A/C-heater control located at the center of the instrument panel.
Circuit protection for the EBL system is provided by two fuses. One fuse is located in the power distribution center (PDC) in the engine compartment and the other is located in the junction block (JB) inside the vehicle.
