A/c on and a/c max greyed out

What started out as my a/c just not blowing cold has turned into me having no a/c at all! I was messing around in basic settings, and since then A/c on and a/c max are both greyed out. I HAVE NO IDEA WHAT I MESSED UP!!!

When i scan now, get 4 air conditioning faults.

Heres the faults……. Any help would be appreciated! I feel pretty dumb right now.
