Thanks for your help. Could you tell me where about these screws are from top corners? I looked again and could not find them. I see a bunch of plastic rivets on the inside of the plastic cover. I already broke one but no screw. Could it be different based on the year? Mine is a 2012.Right under the lip of the hard plastic back are two indentations (one on each side). Phillips head - just unscrew the two screws and lift the back off. There is a plastic piece on each side that fits into the top of the seat back (almost like a hinge). Just reverse to put back together. Hope this helps.
