2004 PT Cruiser rear Middle Shoulder belt wont retract
 

The middle shoulder belt that has the retractor in the back of the seat for some reason would not retract then when I opened cover and manually retracted it now it will not release so I cannot raise seat.
The seat is now in the down position as if I were going to remove it and the seat belt is not releasing.
According to the manual it should not be doing this LOL
Any Ideas how I can manually release it or does it need replaced??
All other belts are fine so it is not due to a wreck or anything.
