Tried a new procedure on my 2024 1500 XD regarding AC issues. My past thread said my machine should be cooler in the cab. This is what I did. I plugged the hole under the hood to cabin ventilation system right after the AC filter , put everything back together as it should be, constantly ran cab temp between 65*-75*. Our elevation started at 4200’ and as high as 8200’. Outside temp high was 92* at the peak. Engine temp ranged from 180*-204*, trani was 155*-165*. This was successful!. May have to remove the plug during the cold season.
