I have a 1997 Chevy Silerado extended cab truck and the seatbelt on the passenger side in the backseat is pulled all the way out and I can't get it to retract. Can someone tell me how to get it back in? Thanks Glen
Most have a rocker-ratchet lever designed to engage when there's a quick de-celeration that throws the weight on the lever forward.
It's in the casing at the bottom of the belt on the floor (although some newer cars actually have it in the seat back now - in which case getting to it is nearly impossible).
There's usually a phillips screw holding the plastic cover over it, and there may be a metal cover hiding it under that too. When you get those off, you should be able to see the ratchets and figure out what has made it bind.
You can sometimes get lucky and park facing uphill. Give the belt a couple good yanks, then let it sit for a few seconds. I've released a belt on a Ford this way once.
