six years difference in our coaches and to remove mine: if the valance is right under a cabinet you will find two or three screws between the front panel of the valence and the day/night shade that drive upwards into the cabinet. The lowest end of the valance sides where they meet the wall you might find a screw angled into the wall. As RWeigant states you might find small angles holding the tops if not under a cabinet.
