Heated Rear Window

WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The HVAC module controls the state of the rear window defrost relay. The defrost system is activated at one of the three following locations: HVAC module, FCIM or FDIM (8-inch [203mm] touchscreen). If equipped, the rear window defrost can also be activated/deactivated by using voice commands. When the rear window defrost relay is active, the rear window defrost grid is energized and the rear window defrost status LED illuminates. For vehicles equipped with a power sliding rear window, the rear window defrost grid (and status LED) does not operate unless the rear sliding window glass is in the fully CLOSED position.

If equipped, the customer can select certain climate control modes/preferences when the vehicle is started using the remote start feature. When the rear defrost is set to AUTO mode, the rear window defrost activates when the outside temperature is less than 0° C (32° F). Once the ignition is cycled to the ON position, the climate control system returns to the previous settings (last ignition-ON cycle) and adjustments can be made normally. For additional information on how to set the remote start preferences, refer to the Owner's Literature.
