Heated Glass - Operation

OPERATION

The rear window defogger (Electric Back Light) (EBL) system is actuated by a momentary switch located in the switchbank, or by using the control located in the U-Connect Touch (TM) screen module. When a rear window defogger switch is pressed to on, the A/C heater module energizes the EBL relay in the Power Distribution Center (PDC), and fused battery current is directed to the rear window defogger grid lines, and to the heated outside rear view mirrors, when equipped. The grid lines heat the glass to help clear the rear window and outside mirror surfaces of fog or frost.

An amber indicator lamp in the switchbank illuminates when the EBL system is on. The A/C heater module contains the EBL system control circuitry, including the timer logic.

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 automatically turns off after an initial programmed time interval of about ten minutes, as long as the ignition is left 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(R) Rear Window Defogger Repair Kit (Part Number 04549275) or equivalent Service and Repair.
