Have you disconnected your battery recently? Sounds like you need to reset your window switches. Here's how:
-Push the window switch down halfway. Meaning, don't let the switch click in the down position.
-Hold the switch in this position until the window rolls up all the way to the top.
-Keep holding the switch (should be about 3 seconds) until you hear a little "click".
-This will reset your automatic window control.
