Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
I know this sounds remedial, but are the door harnesses connected properly? Are you sure the windows worked before you replaced the doors? Can you hear anything happening in the door when you try and move the window switch? Do the door locks work on that side?
There must be a connection problem. Did you replace the doors your self?
And all the connectors were the same on both doors? The door separation point at the jamb looks ok?
I'm researching the wiring diagrams right now, so give me a few
I'm attaching a picture of the connector for the door separation point. I have a feeling they aren't installed or seated properly. Can you disconnect the driver's front door and measure voltage at pins 7 or 8 when actuating the window switch.
I would just take the door panel off and measure the resistance to ground at the ground wire for the door lock. That would confirm you have a good connection through the separation point. The only thing in common is the front fuse box assembly (All Activity Module) and that powers up the other doors as well so I doubt you just shorted the side that you replaced.
Ok, great. I'll be around. I think the website or my computer was having trouble connecting just recently in case you were wondering about the prolonged response.
We're you able to check the door yet?
