no power to window switch? Power windows not working. Changed window switches and found bad ground. Ran new ground. Three windows now work but drivers side window has no voltage to window motor plug.

That circuit does not use a fuse. It is powered by a circuit breaker labeled "ACCSRY PWR", on the yellow wire. It is in the box under the dash on the driver's side but it sounds like you have a window switch that is out here is a guide to help you confirm the issue.

"circuit breaker labeled "ACCSRY PWR", on the yellow wire" What else is powered by this breaker? My driver side window randomly goes down by itself but then hesitates to go back up. So I replaced the window motor and switch everything works great! thanks for the post.
