No bus code
 

I recently experienced a no bus code all the warning light are on and none of the gauges work but my car still runs. The only thing I have noticed is that the air conditioner isn't blowing cold air, sometimes it goes away for a short while 10 15 minutes but then everything above happens again . Once again it still drives please help me I've never seen this before and everything I read other people have the same issue except that they can't start their vehicles

What are you driving?
