My 2003 1.6 active has just failed it's first MOT because the middle rear seat belt won't pull out. It has hardly ever been used. It moves half an inch then locks and no amount of coaxing will get it out.
I've taken the seats out with a view to investigating the inertia mechanism, but can't seem to get anywhere near it. The seat covers have a nice zip system that is sealed at both ends. HELP!!!!!!!!!!!!!!!!!!!
