Customer Question
Drivers door lock will...

Drivers door lock will not respond to Key Fob button to lock but unlocks OK. All other locks respond. Door will lock with key inserted.

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix with a Mercedes. The Mercedes Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.

Not much to tell

Mechanic's Assistant: Are you hoping to fix this yourself?

Probably not but the car is old and not worth spending a lot on

ok, you have to replace the latch in the door, there is a vacuum element that pulls the lock down and pushes up with air pressure, it is leaking most likely or the line that goes to the latch is leaking. hope this helps. you will have to remove the door panel and access the latch and lines.
