Driver Side Rear Door Window Operation
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.
The master window control switch communicates to the DDM through a LIN. The DDM communicates to the RDM through a LIN. The rear door window control switch is wired directly to the RDM.
When commanded by the master window control switch or the rear door window control switch, the RDM supplies power and ground to operate the rear door window regulator motor in the desired direction. The RDM monitors window glass position through feedback from 2 Hall-effect sensors (integral to the rear door window regulator motor). If there is an issue with the Hall-effect sensor circuit(s), the RDM only moves the window in 500 ms intervals (the driver or rear door window control switch must be released and activated again to move the window).
