I flopped down both rear seatrests in my wagon several days ago. When it came time to raise the backs, the narrow seatrest raised up, but the wider seatrest would not because the center seatbelt would not release. You can only raise the back up about half way before the seatbelt tightens. It managed to jam somehow, and no amount of jerking or fooling with the belt on my part made it release, so I could right the back of the seat. I know this means taking a wrench and unscrewing the belt where it bolts to the floor, but what is wrong with the seat belt mechanism inside the back seatrest? Will I have to go buy another one or can I take the back off the seatrest, and fix whatever is wrong? Dick
