06 2500 HD drivers door locks every time I close it. Other three doors working fine. Any ideas
It almost sounds like you are going to need a new door latch. I have seen doors lock by themselves for the action of closing them. Take the door apart. Unplug it from the wires and then use a screw driver to operate the door latch. If it still locks itself with it being unplugged. Then I would say you need a door latch
