i know it's a long shot, but i'm willing to bet you dont' have splash gaurds in your fenderwells... I checked everything you did, and everything was good.. passenger side window worked, and drivers side worked SOMETIMES, but not all the time.. turned out since dude man before me took out the fender linings, it had thrown sand and water and had actually ATE AWAY at the boot that covers the wires going from the door to the car, and water got inside and started to corode it.. basically fell apart in my hands when i found out that it was the problem.. if that's the problem, just go to the junk yard and grab you one and stick it in your pocket... around here they don't like you cutting the harness without buying the car, because they say that no one will buy the car (which is totalled) if any of the wiring is cut....
