In three of the cars I have owned that had power windows, the molded nylon/plastic/??? piece that supported the window glass and frame weight was what broke. Window glass can be heavy so down the window goes! The heaviest was the front windows in my wife's 2003 Caddy Deville and they weighed a bunch. The 1987 Porsche Turbo were lighter and the wipers on the glass fit a lot tighter so they sort of wiggled downwards.

The nice thing now is that ********.com sells the movement parts without that super expensive motor so it is an easy fix.
