Stuck on heat

[Bettyjet]

Hello
I have a 2016 ram 2500, hemi 6.4 and I turned the heat on this morning and this afternoon when I went to come home my ac won’t cool it’s stuck on heat. Any ideas what is wrong. I live in south Texas and need my air conditioning

Have you noticed any other symptoms? It could be the HVAC module. Mine was stuck on heat. Mine was still under warranty so I let the dealership replace it. But you could replace it yourself if that's the issue.
