[MBZ] 300SDL Door locking system

2013-12-21 Thread Ralph Robertson
I noticed this morning that my driver's door no longer will lock the car. The key just moves to the right without any action. The trunk lock will still lock and unlock the car though. I can unlock the driver's door with the key, but cannot lock it again. I have to go to the trunk, unlock all

Ralph, Clarify something if you would: Are you saying turning the driver's door lock with the key doesn't mechanically lock/unlock the door, or the mechanical part works but the central locking system doesn't respond? Dan On Dec 21, 2013, at 8:28 AM, Ralph Robertson wrote: I noticed this

ok, that is the logical area where the problem exists. Probably disconnected, somehow, from the locking mechanism. Thanks, Ralph On Sat, Dec 21, 2013 at 9:18 AM, Mitch Haley m...@voyager.net wrote: Ralph Robertson wrote: Is this just a connection inside the driver's door? So

Then it sounds like a linkage issue. From what you describe the linkage sounds like it's come loose or is disconnected between the pin on the back of the lock cylinder. Since this is independent of the mechanism used to unlock the door it would explain why everything else works when you

If there are no mechanical issues I've seen the case where the logic in the vacuum pump gets confused, and resetting it (by unplugging for awhile) brings it back to normality. But it sounds like you have a mechanical problem. -- Jim ___
