This is very interesting and useful to read. Thanks for all the great info. I have a 72 280 SE and my passanger window does not go up all the way. The motor is still working but it seems striped out when it is almost completly rolled up it stops moving but makes a bad noise. Any suggestions on that one? Also, my moon roof does not open but I can hear the motor working, I found the motor and mechanical gear in the trunk and messed with the nut but am afraid to mess to much as I may make it worse.
