Heated Rear Window

WARNING: This page is about a different car, the 2012 Ford Pickup. 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. When the rear window defrost switch (integral to the HVAC module or FCIM if equipped with navigation system) is pressed and the engine is running, the HVAC module activates the rear window defrost relay. 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.
