Joseph, I remember watching a mechanic replace my driver side window motor (w123).
He did it by himself, methodically.
Remember the set up and lay it down
in such fashion as to be able to reassemble
without goof ups.
I did have to lend a hand in holding the window
up when it came time to line it into the
'support rail'. That was one of those irritating
aspects. If it does not set right, then you
end up going back and forth, quite methodically,but can get one hot under the collar.
I realize this is a very general anectdote.
I wish I could be more detailed in the parts
descriptions, but me is tired.
If ya have a good memory, great. Make a sketch for
re-install reference (or digital pic).
It saves me all the time with DIY jobs.
