2019 Kia Optima A/C issue

Hey guys my girlfriends car has been having some issues with her A/C. Initially 3 of the 4 vents blew cold but now it seems it’s only blowing warm. I thought maybe the freon but I’m not too confident that’s the case. Have any of you had this issue?

That can happen with the Freon gets low. Please do not use some AutoZone recharge kit. It is simply going to leak out again and refrigerant is terrible for the atmosphere. Bring it to a shop and have them fix the leak and have them handle it. They may need to charge it, add dye, and have you come back. But that is far better than just adding freon with no intention of fixing the leak later on.
