Removed seat to get access, pulled away upholstery. Cable is still connected to handle at top of seat, but cable is very thin and disappears behind a motor in the seatback. I tried to remove the motor to get access but remving the only visible screw gained me nothing and was nearly impossible to replace. So I'm stuck and beginning to wonder that since the cable is so thin, it couldn't possibly be releasing the seat, but is probablyn operating a switch. Anyone know how the top seeat release handle works? Anyone had this problem? anyone know how to fix this problem?
