Here is a J-Peg of the power window circuit from my color coded schematics.
It may be difficult to override the circuit because it goes through a Computer data line #10 Brown to (19 Brown wire 1046) to send the signal to the driver side motor, and through #10 Brown to (19 tan wire 1046) for the passenger motor.
However, Good Luck in your quest and report back if it can indeed be done without shorting something out.
Just remember-- you might have a very hard time opening or closing the door with the window locked in the fully raised position. The window seals are in the way.
(The C6 indexes the window up/down slightly for opening/closing the door)
