I am needing to move a hot water heater in my wife's 99 4Runner and for the live of me I cannot raise the back seat bottoms up. This first happened with the driver's side and now it is happening on both sides. It seems more than kid's goo or junk stuck but neither side will not budge at all. I remove the headrest on the seat back, and the seat backs will move as far as forward as possible but I cannot pull up on the seat bottom loop at all. It is as if they are locked. Any advice greatly appreciated. I need a hot shower!
