I have the M-B chassis book for my 1979 450SL, but there's nothing in there on removing/installing a window motor. Plenty of info on adjusting the windows as to upper/lower stops, preload angle, etc. But only photos of hand-crank windows. No mention of electric window lifts at all.
Well, my passenger-side motor finally quit, probably the brushes are shot after 30+ years.
So...is there an archive on how to do a window motor removal/install????
