check your window frames.They can get bent out of shape from slamming doors,accidents,attempted break ins,etc.With the window down open the door and put a dollar bill between the window frame and the roof line and close the door on it,if it slides back and forth you have an air leak.Open the door and hold it stationary while you bend the window frame in.Close the door and recheck it
