I would look for clues in the door, but it is possible that a wire
going through the door into the body pillar might be work hardened to
the breaking point. The relay is possible. Bear in mind that BOTH
windows are on the same fuse. Have you put in a new fuse?
While taking the door upholstery apart on my newly acquired '85
300TD in order to use rust converter and undercoating/rustproofing
on the interior of the doors, I started with the LF door the other
day and the electric windows for this door and the RR door stopped
working after reassembly. I figured it may be the ice cube size
window relay up behind the instrument cluster, as I had this problem
with my '84 300D some years ago and unplugging and replugging this
relay resolved the problem. But since there doesn't seem enough
room to get my paws in behind the instrument cluster to disconnect
the speedometer, oil pressure line, and electrical connector in
order that I may remove the instrument cluster and deal with the
window relay. I pulled the LF door upholstery back off today in
order to check the electric window ground and voltage. Ground is
good and, when I was measuring the voltage across the terminal block
on the door the electric window motor was making some faint noises
as if it was trying to operate. I thought that to be odd,
disconnected my voltmeter and operated the LF electric window switch
and the bloody window operated. I checked the RR window and it
operated as well. I reassembled the LF door upholstery and you
guessed it, the LF and RR windows are inoperative again. Clue(s)?
TIA.
