Ive gotta 95 grand, and I'm sure I'm not alone in hating the fact that when I try to roll down multiple windows simultaneously it takes a while for them to go all the way down. Ive gotta a rookie background in electronics, so wiring and understanding how it works isn't really too bad. What makes the most sense to me is that, for whatever reason, the power windows are wired in series. So when you roll multiple windows down you're getting a low drop in voltage across all the windows. Is there any way to rewire the windows in parallel so the suckers will get the power they need to move?

 

I do not believe that they are in series. I had to change one and was 12v motor. It will not run on 3v. My windows were going slow so I spray WD40 on rubber. They are working faster. The older the motor gets, the more amps will draw. Looking at the wire size it would not transfer more that 5amp.
Grease the rail and see what happen.

 

Same advice that I would give. grease the tracks and wd40 on the window guides.
