2017 GMC Sierra 1500 Denali - HVAC issues

jav08408

I have a 2017 GMC Sierra and every time that I turn on the Auto function for the temperature control system it turns on the AC. On a long road trip I turned the auto function on when the outside temperature was 25 degrees Fahrenheit. I had set the temperature up to 80 degrees yet the AC never went off. The only way that I have found to disengage the AC is to de-activate the AC button. However, when I do this, it turns the Auto feature off.

Is the Auto feature working correctly for my vehicle?

Air conditioning isn't just for cold air. It also removes humidity, to keep your windows from fogging up.

In auto, it's likely operating as intended.
