Description And Operation: Operation

The rear window defogger (Electric Back Light) (EBL) system is actuated by a momentary switch located in the Integrated Center Stack (ICS), or by using the control located in the U-Connect Touch ™ screen module. When a rear window defogger switch is pressed, the Heating, Ventilation and Air Conditioning (HVAC) module energizes the EBL relay in the Power Distribution Center (PDC), then fused battery current is directed to the rear window defogger grid lines and to the heated outside rear view mirrors, as equipped. The grid lines heat the glass to help clear the rear window and outside mirror surfaces of fog or frost.

An indicator lamp in the ICS illuminates when the EBL system is on. The HVAC module contains the EBL system control circuitry, including the timer logic.

The EBL system automatically turns off after an initial programmed time interval of about 10 minutes, as long as the ignition is in the RUN position. If a rear window defogger switch is pressed to on again after the initial time interval has expired, 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® Rear Window Defogger Repair Kit or equivalent. Refer to GRID, DEFOGGER, STANDARD PROCEDURE .
