Sounds like the ball, toggle lever or pawl is stuck.
You need to take the bulkhead trim off to reveal the mechanism. (plenty of posts on here of how to do this)
Unbolt the belt mechanism and take it off the bulkhead for easy access. You can either take the whole thing out or sit in the car and fix it in your lap.
Now the most important bit.
The belt reel has two end caps. Shallow and deep.
DO NOT take off the shallow end. This houses the spring and you'll be in a whole load of hurt if you do.
The deep end houses the lock mechanism. There's a weight arm or ball bearing usually inside (depending if the PO has swapped out for a different brand)
This ball or weight should be free to roll within its cup. This moves the toggle lever arm up and down, which should be free to move also.
The toggle lever arm pushes the pawl in and out of engagement with the gear wheel on the end of the reel.
All parts should be very free to move.
When testing you need to hold the assembly vertical and level as it would be when in the car otherwise its prone for the ball (or weighted lever in the other design) to start to lock up your belt. (this is why sometimes if you park on a steep hill or camber you cant easily pull the belt out)
Chances are it just needs a clean and a little light oil.
Great info ! Thanks
