Air Bag Light On

I have 1999, Silverado, C-2500, 6.0Ltr
I recently changed my battery when power was restored the air bag light came on and has stayed on. During the summer I had the A/C coil replaced also. Autozone checked for codes but none appeared. Does anyone have ideas? Not sure where to look for the sensors to see if one is disconnected. Any help gladly accepted to keep me out of the service bay. Thnks
