If you can get to the console wiring it's easy to plug the rear windows into the opposite side switch (confirm condition of console switch - rear switch must be plugged in). That's where I started. Next was adding power directly to the motor. I'm not sure that one direction insures the opposite also works but you could be right. When you pull the door switch out. Look at the wiring: probably 5 wires. 3 bundled together come through the door. The other 2 go to the motor and those are the connectors to apply the external 12V. Reverse to change direction. Had you known - you'd have had that window up in 5 min. I've left mine unplugged so it can not be lowered until I fiure out the short, ground, etc.
