I have a 09 Pontiac G8 and my passenger seat way starting to rip pretty bad so I found a used seat that was in really good condition and after disconnecting the negative battery terminal and removing the seat belt and seat and put in the used seat. I now have a air bag fault light and it won't go away. I thought it was the airbag module so I took out my original airbag module and put it in the used seat and still same airbag fault. Can anyone help me? Or have any insight. Thank you.
