The plastic retainer hooks that hold the pockets and trim panel are broken. This happens a lot. I think MBZ really fell flat on their faces when they used this method to hold trim on. Retainer hooks arepart of the pockets and trim panels. You will either have to replace those parts (good luck), or try to repair the plastic hook retainers (really good luck)
