you have accidently pressed the "window lock" switch on the driver's door. the switch is at the front of the front door window switches on the driver's door panel. It has the picture of a window on it with a X on it. The switch locks the three other windows so that kids can't open them and climb out while your driving. all you need to do is to press the switch in again and the window lock will be turned off and you can use the other three windows.
