Rear Window Defogger System: Operation

Circuit protection for heated grid is provided by:

Fuse 12 (EBL) located in the Power Distribution Center.
Rear window defogger relay (EBL) located in the Micro Relay Bank.

When the button is depress to the ON position, current is directed to the rear defogger grid lines. A yellow indicator within the center of the button will illuminate while the defogger is ON. The heated grid lines will heat the rear glass and clear the window surface of fog or frost.

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.
