Window shades

Hi all
The little tiny screw on the window shade came out so one side of the shade is falling down. I cannot get my fingers or a screwdriver back there to fix so must take the valance off. Cannot see how to take it off! I have a 2008 3580RL
Thanks!

There are square head screws on the valance and a L shaped bracket which is screwed to the wall and the valance. Remove the screws from that and it will come right off.

Some valances don't have that "L" bracket. If this is your case, the screw is hidden in the fold of the fabric on the outer lower corner of the valance.

Thanks guys, going to visit the Big horn bar and grill tomorrow and will check it out!
