I took my car to get a minor dent fixed on my rear bumper. When I picked up my car from the shop the driver's side seatbelt was locked up. I know that my car was crashed and the airbags were deployed. It was restored, even tho the airbag light is on. The seatbelt has been working fine for the last 8 months so I dont understand why. I think the car mechanic mesed with something but wont admitt it. To my understanding when a car crashes and the airbag goes off the seatbelts lock up and they have to be replaced and the system resett. That would mean that the seatbelts I have now are new. The car mechanic told me the system could just automatically make the seatbelt lock up. Please help me figure out wether I should fight them on this or if there is an easy way to just fix it myself.
