Electrical problem
2002 Chevy Impala 6 cyl Two Wheel Drive Automatic 75000 miles

power car windows do not work, tried power relay from passenger side as suggested by autozone, it did not make windows work, also tried new swith which did not make windows work, they make buzzing sound when attempting to put down drivers window, but to no avail. Did get new 30 AMP Breaker, windows still not working. I heard something about putting power to the motor itself, but not sure how to do this. Please advise the possibilities of what is going on & why?

When you try to operate windows, is circuit breaker hot to the touch? Main voltage to master switch, yellow wire, main ground is black. There is a lock-out switch at master switch, if it is tripped, only the driver can operate any of the windows. Usually the driver window motor will fail before the others, obvious reason.

Because it is a reversing motor, the circuits at the motor switch voltage and ground, depending on up or down.
