Heated Glass: Description
WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
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. See Fig 1.
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 timing circuit integral to the body control module (BCM).
Circuit protection is provided by two cartridge fuses. The fuse located in the junction block (JB) is for the control circuit and the fuse located in the power distribution center (PDC) is for the heated grid circuit.
