QuestionI need to remove the right rear door panel of my 2000 300M,in order to find out why the lock emits a "screech" when the door locks automatically. I have a part number for the "lock" from the dealer, but I suspect there is more than just a lock...some kind of actuator?...a latch?...gotta be more parts. But I don't want to damage the door panel by forcing it open incorrectly. Have been searching for a manual that will show how to do it, but unable to find one anywhere!! If you can help I would really appreciate your expertise. Thanks Dar
Answerthe latch/door lock actuator is one assembly.
