Switch, Defogger: Description
WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The momentary push-button switch for the rear window defogger (EBL) system can be located in the A/C-heater control in the center of the instrument panel.
There is an option for the switches to be located within the U-Connect touch screen. An amber indicator will illuminate to indicate when the EBL system is turned on for either switch.
