I vote for the switch -- can you take them out and clean them? If that
doesn't do it, it might be one of the plastic slides is broken/jammed.
I had a rivet shear on the geared raiser arm that is driven off the
motor gear, had to bodge a fix on that if I recall it acted sorta the
same. If not the switch you gotta get in there.
Can you squeeze the window from both sides and push up while someone
works the switch?

I am in big trouble. On a road trip yesterday, I lowered the L rear
electric window in her W123 300CD. Now it won't go up. Fuse is OK - all
other windows operate normally. Window is now 3/4 of the way down, but
neither the master nor the rear window switch has any effect in moving it
up. How should I go about troubleshooting this w/o having to remove the
window regulator, which involves removing the back bench seat + seat back as
well as the rear interior panel. I am also dreading being unable to raise
the regulator to a position that would allow be to swap out the PW motor, if
that is what's failed.
Are these motors bipolar, i.e., can one direction fail?? Has anyone else
encountered this problem before?
Help me out please...
