Hello and welcome to Just Answer!The air bag light can illuminate for many reasons and I will need to know what the fault code is before saying what could cause this. There are numerous fault codes and without knowing what code has been set, it is impossible to give you an Answer. Would you be able to get the air bag control module fault code read with a high end scan tool?
This could be caused by something as simple as a fuse or something more. The first thing you should do is check all the fuses and let me know
Is that something that can be done with a fault code reading from Autozone?
I don't think Autozone can read air bag codes, but you could ask them. If they can't you will have to see if a shop can read them. You don't need to go to the dealer, any high end scanner like Snap-on should be able to get the codes.I would start by checking all the fuses, a burnt air bag fuse will cause the light to illuminate.
