Okay vette guru's I am not the most mechanical person but i am trying, here is what i got 70 Lt-1 with power windows passenger side seems pretty smooth and fairly quick and steady, driver side starts out with good power seems to fizzle out toward full up postion to the piont of not sure if it is going to make it but it always does.. looking for starting point or a path of elimantion. please go slow....

I think your problem is more mechanical than electrical. Peel of the door panel and grease the window tracks and roller wheels; lube the pivot point(s) of the regulator gear and regulator arms. Check the condition of all rollers.

It is also possible that the motor itself is due for a rebuild. But, I'd start with the mechanicals first. Good odds that something is worn and/or binding.
