Reset the window memory.
With door closed, open the window all the way up, then once it's at the top, hold up on that switch fully for 5 seconds. Then click it to roll it all the way down, then press the switch this time and hold it for 5 seconds. See if that works for ya. Usually have to do this after a battery reset etc.
