Hi guys: I disconnected my e320's battery for 20 minutes hoping to somehow fix the BAS always on problem. The BAS problem was fixed with replacement of a bad stop lamp switch, but now 2 of the windows on the car will not move up or down with the one touch button. I can still open and close them by depressing the button halfway. But they won't budge when i fully depress the buttons. Does anyone have the same problem after disconnecting and reconnecting their battery? TIA!! Mars

Try holding the up or down window button for 60 seconds. That's supposed to reset the window switch. Not sure if it'll work but worth a try.
