airbag light in 911
 

Hi, does anyone know anything about the airbag light going off? I just bought a 1999 carrera and it went off couple of days ago. I called a mechanic and they said that it has something to do with old sealbelt clip and faulty wiring underneath the seat? and it will cost over $600 to fix it? Is that true? Has anybody else have or had the same problem? I would really appreciate some help. Thanks
Chris
