As far as the window motor goes, you might just try tapping on the side of
the motor case with a small hammer or a combination of the hammer and a long
"punch" if it's hard to reach. Sometimes they just need to be jarred a bit
to un-stick them. Operate the switch with the engine running just to be
sure you have good electric power.
Yes, they can be a BIG pain in the rump to remove, a very last resort.
Good Luck!
