Heated Wiper Park Overview
WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
When the rear window defrost button (integral to the FCIM) is pressed, the FCIM activates the rear window defrost relay (located in the BJB). When the rear window defrost relay is active, the rear window defrost and heated wiper park grids are energized. The rear window defrost and heated wiper park can also be activated/deactivated by using the touchscreen or voice commands.
