Hi to normalize the rear door follow this procedure.
How to change rear door lock on w164 ml350.
Open the rear door from the rear handle.
I own a 2006 m class w164 and i want to repair the rear door lock.
The driver s side door lock stopped working in my ml some months ago.
Next go to the switch in the driver s door and raise the door the rest of the way by holding the switch in the open position until the motor shuts off.

Now the rear door on the same side has the same problem.
The door should raise to the garage position midway.
The door should then function properly.
Now i am looking for a description how to remove the door panel of the rear door.
It has to be manually locked and released.
