A blinking airbag light typically means a short in the air bag system. the connectors in this system are gold and rarely corrode. so either something came unplugged or was unplugged while the battery was still connected. and they probably are not but deployed air bags will cause the light as well. and yes the whole a car wont run if the air bags are deployed thing is a myth. I've been a mechanic for years and i have set off an air bag once by mistake. you have to take it to a dealership so the problem can be corrected and the light reset a special computer is needed to do this and they run about $500. very few shops "on the side of the road" are equipped to do this. it shouldn't be less than $100 for this but not more than $200. also if the vehicle is still under warranty than it may be free depending on what caused it.
