HVAC 13/31 - 41 Trouble Codes

[Subix]

So my AC is acting up lately and sometimes not coming on at all. If I restart the car it may sometimes work but not always. Then if I shut it off, open the car hood and then slam it shut, it usually will come on when turning the AC on again.

Finally had some time to find how to pull the codes and they are:

13/31

i pressed auto after that and then it goes to 41 and sits there. I guess it's prompting me to do something at this point but I don't know what.

Anyways, what exactly is the PBR circuit? Is that part of my HVAC electronic controls section or possibly something else? I guess I'm only posting to see if someone has had this exact same code before and knew exactly what it is that is causing this fault.

Otherwise, I guess I will eventually take it to my local shop and give them the malfunction codes/guide to pinpoint the issue... I have no multimeter.
