Rear Window Defrost
WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.
When the rear window defrost switch (integral to the HVAC module) is activated, the HVAC module activates the rear window defrost relay (located in the BJB).
If equipped with a touchscreen, the rear window defrost can also be commanded on and off using voice commands or by touching the rear window defrost button located on the touchscreen (FDIM). For additional information on voice or touchscreen commanded features, refer to the Owner's Literature.
The HVAC module deactivates the rear window defrost relay when any one of these conditions is met:
- The rear window defrost switch is pressed when the feature is active.
- If equipped, the rear window defrost is commanded off using voice command or the touchscreen interface when the feature is active.
- Ignition state is changed from ON to OFF.
- A predetermined timer completes.
- Battery voltage has dropped below a specified threshold (load management strategy).
