ok. so my son in law was driving his and my daughters monte carlo. all of a sudden , the air bag lights came on, and the whole car shut down. electronics and all. completely shut down. car wouldnt move. wont even make a clicking sound to turn over. its as if it DIED. need opinions .
somene said something about an electronic reset button in the trunk, but figured ide get sound advice instead of a part time wannabe mechanic .
any advice is good advice .
also took out the onstar box, is that safe as well?
dont know much about cars so asking for them .

 

Well if anyone wants to give advice on this they will need some more information. Year, model miles etc. What has been done.
