I have a 2015 Ram Promaster and the last few days have been sporadically getting a "Rear Door Open" warning (Along with a chime) even while the doors are securely closed. It's freezing cold up here so I haven't put a lot of time into looking, but I can't find any buttons or obvious sensors on the doors that might be out of line. Does anyone happen to know where they might be? Are they built into the latch? Or could this be an electrical issue? Any help or advice is greatly appreciated!
