i bought a new window regulator(it comes with the small motor attached to it) from the ford dealer, cost about
$120.00 bought the Haynes book and it shows you how to remove the inside of the door and the window glass to replace the window regulator... i tried to fix the broken cable inside the window regulator, i have a small metal cutting lathe and can make most parts,, but on this i just gave up and bought the new window regulator.... did not take long to fix it....
hope this helps.
