I just bought another Crown Vic. When I got it, the airbag light is flashing code 51 when you first start the car up. I've looked on the internet, and its states that its some kind of thermal link. I have not a clue where this thermal link is located. I don't know if there refering to a fused link in line somewhere. If someone has encountered a problem similar to mine, some feedback would be greatly appricated!
