2002 Oldsmobile Alero airbag light will not go out.
 

After removing the seats and headliner for cleaning and reinstalling them, the airbag lamp will not extinguish. All connectors that were removed have been double checked for correct installation and the airbag fuse was verified good. I attempted to read the diagnostic codes, but the reader reported 0 faults. I even cleared it for good measure, but no change.

Might try unhooking the ground from the battery.
