The locks weren't working and when I replaced the graphite pump inside the central locking pump, there was water damage to a small circuit board. when I tried to clean it up, the prongs gave way because of rust. Now the windows won't go up or down. I need to raise the driver's window.

you should be able to unplug the window motor and give power straight to it and raise it up , if giving power & ground to it make it go down , then reverse polarity and should go up , you can use a power probe or a spare battery 12 v and 2 wires .
