Passenger Door Window Control Switch
WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The passenger door window control switch contains momentary contacts (one for each window switch direction). The PDM provides a return (ground) for the passenger door window control switch. When the control switch is activated, a ground signal is supplied to the PDM to operate the passenger door window regulator motor in the desired direction.
