Recently after a major cold snap my airbag light came on and the horn stopped working. I have checked the fuses but they all seem to be in working order. 
  
I was wondering if anyone has had a similar problem or may not know what is going on. 
  
I am trying to get to the bottom of this problem. 
  
Could this be a relay switch or something else? 
  
Please help me if you can. 
  
THANKS!!!
