The rear window defogger system, also known as electric backlight (EBL), consists of two vertical bus bars (1)
and a series of grid lines (2) fired onto the inside surface of the rear window (3).
The EBL system is turned on or off by a push-button switch located in the A/C-heater control. Refer to

The electric backlight (EBL) system is controlled by a momentary push-button switch (1) located on the A/C-
heater control (2) in the instrument panel center bezel. When the rear window defogger switch is pressed to the
On position with the ignition switch in RUN, the switch sends a request signal over the CAN-IHS bus to the
totally integrated power module (TIPM), which provides a ground path to energize the coil in the EBL relay.
When energized, the EBL relay provides battery current through a fuse 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 (3) in the A/C-heater control will illuminate to indicate when the EBL system is operating.
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 the On position 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® Rear Window Defogger Repair Kit (Part Number 04549275) or equivalent. See STANDARD
PROCEDURE.
Circuit protection for the EBL system is provided by fuse 13 located in the TIPM.
DIAGNOSIS AND TESTING
REAR WINDOW DEFOGGER (EBL) SYSTEM
NOTE:
The EBL system turns off automatically after 10 minutes of initial operation.
Each following activation cycle of the EBL system will last 5 minutes.
