How to Improve Power Windows

[Armyvet25]

Ok, gotta tell a funny story relevant to this topic...

I had a 77 grand prix, power windows, passenger side sometimes went up or down, sometimes it didn't, figured the motor was worn out and needed replacement, this was correct, but...17 year old me and broke as egg shells on halloween night, I decide to drill out the rivets(some are screwed) and see what actually wears out slowing down window motors till they eventually stop. Brushes...yup, the carbon wears out till they lose contact, bright me thought, a brush is a brush right??? and I had taken an alternator apart before already at this age and new they had them inside and I had an old junk one laying around so I took it apart...hmmmm, problem, this brush is way to wide and long as hell, but, it's carbon, so off the grinder I went making it the right kind of narrow to fit in the window motor, the the copper wire was thicker as well but didn't affect anything...or so I though, I soldered it in, reassembled the motor, installed in the door, after a couple times up and down for it to settle into the armature and...HOLY SH%%, IT WAS THE FASTEST ANY WINDOW IN THE WORLD WENT UP AND DOWN, THOUGHT I WAS GOING TO SHATTER IT, and we're talking a rather large heavy window mind you. so I don't know if it was a combination of the brush or heavier gauge copper wire or brush composition or what, but nothing ever compared to that window, not since in 40+ years lol.

Any ideas why??? I'm all ears.

Clips to hold the switches are in. 
But the 12 I got look like SJ ones. They will hold the switch but might have to be modified to accept the connector.
