Hiya! Thanks to all the helpful advice I've gleaned from this forum, I've successfully removed the door panel and replaced the seat adjustment switch on my 1990 300E passenger side door. Everything went back together just fine, but the key doesn't work quite right in that lock.

It worked ok up until someone smashed the window a few months ago, and the window replacement guy left the lock knob disconnected. I thought all that was needed was to reconnect that into the two tangs inside the door, and all would be well, but although the key seems to connect now, it doesn't lock or unlock the door. The locks work just fine on the driver's side door and the trunk latch, and all the knobs go up and down as before, just not with the key in the passenger door.

I'm new to MB's, fell in love with this one, so I'd like to take care of all the little problems like this myself, although part of the reason for keeping it is that I have a good mechanic in my neighborhood. However, I'm not sure where to start on this problem. Is there another thing that should have been connected while the door panel was off?
