How do you fix a seat belt that will not pull out?

If a seat belt won't pull out, first check for any obstructions in the belt's path, such as debris or twisted fabric. Ensure the retractor mechanism is not jammed; gently tugging on the belt while pressing the button can sometimes free it. If the issue persists, inspect the seat belt assembly for signs of damage. If these steps don’t resolve the problem, it may be best to consult a professional or replace the seat belt.
