I have a strange issue, the seatbelt minder light never comes on nor the chime and the airbag fault light is on full time. Once in awhile, when the weather is just right, the seatbelt minder will come on and then the airbag light goes out and all is well until I start it again and then it's back to square one again. I know the seat pressure switch, the seatbelt connector switch all connect to the airbag system to determine whether or not to deploy an airbag based off if the seats are occupied. I just need some advice on how to start troubleshooting this monster to get it fixed. I've had the driver's side recall on the airbag fixed already. 2011 Mustang V6 manual, no power seats.
