Re: driver window no power
One way to check that to see if its the incoming wires to the switch......
Strip off a tiny piece of insulation off of the incoming wire and do the same to the wire that it mates to on the other side.
Then use a jumper wire with alligator clips on either end and simply clamp them to the exposed wires. If the window operates, then its the switch. If the window still doesn't work, then its not the switch but somewhere else.
The switch itself could also be tested with a meter or test probe. Test leads up inside connector holes with probe and see if light comes on.
