Air bag light showing at the dashboard. It's intermittent happening. The air bag light dissapeared for a month then iy\t's back again. It usually appears for a couple of days. What could be causing t

The airbag light on the dashboard comes for few reasons, either there is a bad connection or connection came loose but than the light would stay on at all times, if it comes periodically than I would look up to the owner's manual and also find the airbag check label inside the car as it might be faulty or in need of replacement. The danger is that if it is faulty it can blow up by itself or in case of accident (hope none happens) it will malfunction.
