THe rear door window glass has become disconnected somehow from the arm that
drives it up and down, so it was just falling down all the way. I had to
open up the door to prop up the window glass with a stick as a temp repair.
I could not figure out how to get the inner door panel ALL the way off,
which I will need to do in order to repair it. I am stuck on how the door
release handle comes off. Something on this mechanism was holding the panel,
while I had it released everywhere else. There are no screws of any kind,
and I was sure that if I pried any harder on the wood-grained
escutcheon.trim around the release handle, I would end up breaking the
escutcheon or release mechanism..
There is a plastic sleeve that covering that screw in the latch area... you
need a tiny screwdriver to pop that cover off.
You basically need a new plastic regulator... like $9 at the dealer... very
common to go bad due to age.
Not hard at all... take door panel off... then three nuts to remove the
window motor/regulator... leave glass in the door...
The only thing you need to watch out when you peen over the new regulator
is... the right side where the regulator should be and a spacer on the
opposite side where you are going to peen so you don't crush the new
The windows on our '85 300D make a harsh mechanical noise when about 1/2
way - We have just been using them from 1/2 up to full up. They will go all
the way down, but it doesn't sound good!
Before I take it all apart, any ideas as to what could be causing the
noise - It happens on both front windows.
