In my 2018 down here if Florida, I have found the "Auto" settings to be useless until the car is driven about 10-12 miles. if its 50 f out an it is set at 70, it will cook you out. if you lower it to 65 the next thing is the A/C kicks in. and the temp plummets. It must be in manual with the A/C selected off to get control.
