WARNING: This page is about a different car, the 2024 RAM ProMaster EV. However, it is still accessible from the selected car via links, so may be relevant.
The Body Control Module (BCM) monitors the operation of the Front Wiper Motor with a wiper park switch that is integral to the Wiper Motor. When the front wipers are in the park position, the Wiper Park Switch sends a voltage signal on the Front Wiper Park Sense Switch circuit. For additional information on the Front Wiper operation, Refer to WIPER AND WASHER SYSTEM .
