2023 Denali Climate Control starts up and works fine for about 20 seconds then the blower cuts down to low. It stays that way until you either key the phone or change over to manual fan. When you change over to manual fan, then go back to Auto it continues to work properly until you cut the vehicle off. This happens every time you start the vehicle. I've noticed the radio also cuts out for a split second a couple of times but continues to work after a few interruptions.
