AC control issues after 5 to 8 upgrade

[Apny2nv]

I just upgraded my 21 1500 DT from 5 inch to the 8.4 screen. I purchased a used 8.4 full stack, but the unit came out of a 21 Laramie with the Duel zone AC controls. My 21 1500 had the 5 inch with single zone system. I installed the unit and it was pretty much plug n play. Radio and uconnect works great, I did have to put in the radio security code. My only issue now is I cannot control the AC system. Is this something that can be corrected with Alphaobd, or will I need to change the bezel to the signal zone AC controls?
