I have an '85 300TD.The passenger side rear door will not open and the window does not work. My driverside door does not lock at all. And supposedly my car will automatically unlock all 4-doors when I put the key in the driverside door, but this doesn't work either. Any suggestions or good web-sites I should check out on how to resolve this issue? My first hunch is to check for vaccuum leaks, but I don't htink that's it because it's only the one door.

Thank you.
