It'* a little hard to follow of exactly where your problem is...both front window, or just the passenger? I don't recall any clear jacketed wires in the door panels, so it would be anyone'* guess what they may have tried to power from that lead.
Are your door panels off? If so, just remove the 3 screws that hold the motor onto the bottom of the window regulator, and take the motor out. Connect power, and see if it works. If it does, lube things up with a good silicone grease, and put it back together. Odds are it will work fine.
If the panels are not off, as a test before removing the panels, open the door, depress the switch in the direction to have the window go down, and give the door a good slam closed. Slam it in a way that you would yell at anyone else if they did it. See if that frees things up.
