Heated Glass - Operation

OPERATION

The rear window defogger system, also known as the Electric Back Light (EBL), is controlled by a momentary push-button switch, located on the A/C-heater control, in center of the instrument panel. When the rear window defogger switch is pressed to on, with the ignition in RUN, a request signal to the Totally Integrated Power Module (TIPM) over the CAN-B Bus to energize the internal EBL high side driver. When energized, the EBL high side driver provides battery current to the rear window defogger grid lines and to the heated side view mirrors, when equipped. The grid lines heat the glass to help clear the rear window and side mirror surfaces of fog or frost.

An amber indicator illuminates in the rear window defogger switch to indicate when the EBL system is turned on.

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

The EBL system will automatically turn off after an initial programmed time interval of about ten minutes as long as the ignition 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 five minutes. The EBL system will also turn off if the ignition is set 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 Service and Repair.
