Ac heat unit on my06 is not turning on?

So my dual climate air conditioner was working last night. until I was trying to find out why, the red lights that normaly light up on navigation buttons steering wheel and head unit were not lighting up. I checked fuses on the car and it now is not turning on any ideas on either of the issues. Lights or air conditioner neither are on seems to be a fuse. What one would I be checking or try swapping with a new one?
