I have a 2004 350Z that was hit in the side. The drivers side curtain and the drivers side seat airbags were the only ones that deployed. I am wondering if I need to replace the seat belts along with the airbags? They move freely and lock up like they should. I have heard there is a procedure to check them with an ohm meter but I'm not sure how to do it. If anyone knows how to do it I would really appreciate the help, thanks.
