The seat control panel is held on by plastic clips that fasten to the backside of the piece that is pulling away. You can use a small flat head to get one started, then try to squeeze your hand in behind the big panel to pop the rest out. I noticed a screw was broken on mine when I first bought it. The larger panel is attached with screws that go into the metal frame of the seat, and you will probably need to put a couple larger screws through it once that access panel is removed.
