OPERATION





NOTE: ATC A/C-heater control shown. MTC control similar.

The electric backlight (EBL) system is controlled by a momentary switch (2) located in the A/C-heater control (1) on the instrument panel. When the rear window defogger switch is pressed to ON, the body control module (BCM) energizes the rear window defogger (EBL) relay. When the relay is energized, fused battery current is directed through the relay to the rear window defogger grid lines and the heated outside rear view mirrors, when equipped. The grid lines heat the glass to help clear the rear windows and outside mirror surfaces of fog or frost.

An amber indicator (3) in the rear window defogger switch will illuminate to indicate when the EBL system is turned on. The BCM contains the EBL system control circuitry including the timer logic.

NOTE: The EBL system turns off automatically after approximately 10 minutes of initial operation. Each following activation cycle of the EBL system will last approximately 5 minutes.

The EBL system will be automatically turned off after an initial programmed time interval of about 10 minutes as long as the ignition switch is in RUN. After the initial time interval has expired, if the rear window defogger switch is pressed to ON again during the same ignition cycle, the EBL system will automatically turn off after about 5 minutes. The EBL system will also turn off if the ignition switch is turned to any position other than RUN or by manually pressing the rear window defogger switch a second time.

Repair of the rear window defogger grid lines, bus bars, terminals or pigtail wires can be accomplished using the Mopar(R) Rear Window Defogger Repair Kit (Part Number 04549275) or equivalent.
