2013 ML350 4matic door locks intermittent problem
So all of the door locks function manually (plunger up down), and the electronic activation (fob or door button) works on all locks except the driver side passenger (rear seat) lock. When I lock the doors, that seems to work consistently every time. It's the unlock that seems stuck on one door (sometimes). If I manually move the plunger to problem door to unlock it seems to start working again. But I leave to go shopping and when I return I can't open the rear door again without manually moving the plunger. It is super annoying. I don't think the actuator is broken - it seems to work. Please help!!! What's the deal!!

DOOR... controler or lock

Hook up a scanner to assess if that door control module is cooperating with lock. Both can go bad just as well.
My fav would be the solderless DCU.
