If you disconnect the battery and lose one touch up/down and or the positive seal function, you need to reset the windows.

This procedure will reset the windows limits so that when you open the door the window will drop the 1/4 inch.

- Sit in the car, and put the key in position 1, so you have power to the windows.

- Push and hold down the window switch, and keep it held down for 5 seconds after the window is all the way down. This re-sets the memory, telling the motor, in effect, “Remember where we are now? ”

- Roll window back up, and release switch.

- Open door. Marvel at the downward motion of the window. Repeat on other side, if needed.
Would this procedure work in the following scenario where the window won't close, but open's about half-way after reaching the top? It is like it doesn't know where the top position is. You can slowly inch the window back up again, but if you do it too quickly, it will retract to the bottom again.
