2013 3500 Duramax. My batteries went bad on me yesterday and after replacing them both today I have no cold a/c. A/c blows hard just hot like the heater is on. Read on a couple forums that I need to reset the climate control and bcm? Anybody gone through this? I have to think this is related.

I can’t remember if I did or not. It happened to me probably 3 years ago now, I don’t think I did though. I found a video on YouTube we’re the guy walks through it on his cat eye duramax. On mine the a/c was working on the passenger side but heat comin out the driver side, of that don’t work for you it’s the actuator
