Air conditioning blinking 5 times and blows hot air

What is your question?

Added freon just to verify no leake and system charged. It is!!! Compressor works just fine engages ad kicks off as needed. Blows fine for a day or two and then blows hot air for weeks. I have a 7 month old baby and 2 other children this is a 2016 model and manufactured 06/15 which I believe had a recall. This is getting old can I please get some help to what this may be. If I need to tear the dash apart and change the actuators I will. Just need to know if that's what they are having issues with now.

What makes this problem better or worse?

Nothing

How long has your 2016 GMC Acadia had this problem?
