not sure what all was meant by the fingers and hands stuff, im not stupid.

J/K.  I didn't realize the gap between the hood and the cowl was enough to see under.  Never have tried looking through there for some reason.  Guess I've never had a reason.  Besides that, if I have my glasses on, I could read it from that distance, probably.  I seldom wear prescription glasses when working on cars, because I can't see up close with them on.  I tried bifocals once.  That was not fun.  I do still wear safety glasses when the work warrants it, though.  I like not getting dirt/acid/oil/gasoline/transmission fluid/antifreeze/younameit in my eyes.  They're the only ones I've got.

either way , something tells me the resistor might need to be variable since the tracks are always the factor of resistance and then you end up with a window stuck at these two points due to crud ect.

Precisely the whole concept behind my long diatribe.  Grease on the guide gets old and sticky, brushes get crudded, new dew wipes go on, just a whole host of variables here that are going to affect it if it isn't a regulated control.  20% speed on a day when it's -10 ain't gonna be the same as 20% speed on a day when it's 110.  There shouldn't be much problem getting the current and voltage feedback for the motor under the console near the switches.  The drop in the wire between there and the windows should be fairly negligible.  I wouldn't bother with any kind of speed control unless I was going to regulate it.  That's exactly why the overload is in the comm end of that motor.  For STALL when the 'operator' forgets to take his finger off the button, or if the window stalls somewhere for whatever reason.  In-Car fires are not nice.  But, upper and lower limit switches are a novel and interesting idea.  Would sure stop binding the bellcrank on the window and flexing the inner door works.

Wait, but I'm confused now on how I can hold both windows and there's not a single problem with the circuit breaker. It's 20A. I would have taken readings but my rearend noise has come back so I've been trying to figure out where it's coming from.


i stopped mine also.  never tried it before,, just for you man:D
