Rear passenger door won't open
I'm struggle to open the rear passenger door.
It was same problem with the majority of the Mercedes.
I was able to remove the door panel and the internal was exposed..
I tried to pull the blue cable but the door still won't open..
I can't remove the metal plate because the glass and window motor is attached....
How can i open the door?
Please help..
I'm so frustrated with this door..
After reviewing the attachment, I need to remove the module first then remove the rear door lock.. install the new one and it should work right?
Thanks for sharing...




I can see individual door modules playing tricks but all at once I'd question it twice

I pull the blue cable, the black cable but the door still won’t budge..
im so frustrated.. tempting to use the old fashion way with the hammer but I may damage something else..

Unlock the car, either remote or switch on driver's door panel... neither the exterior handle nor cable with blue housing will release the catch? If that's the case, then grind off the rivet in the upper right corner of the panel and that should release the lock from the panel itself. Pull the panel and associated bits... now you can get in there and have a better look at whats happening.
Unfortunately to release the door handle and then the lock, you need access from the inner door edge, which is obstructed as the door is closed.
