Hello, I have a 2010 ML350. The issue is that the right rear door handle is stuck in a mid way position (not in the closed position and slack, moving freely to about half way to the pull) and does not open the door from the inside. The door will open from the outside with no problem. I checked the child lock and it appears to be in the correct position. The central locking works fine. Is this the spring issue, broken cable clip, or a bad actuator? Thanks for your help.
