I disconnected the battery for 15mins and next time I started it up it worked.

Hello, Last week I purchased a new 2018 Silverado LT Z71 double cab. Initially the climate control worked fine. However, while driving home today I noticed the fan would not turn on when in auto mode despite the cab temperature being in the 80's. Manual fan works fine and will blow cold AC but as soon as I press the auto button the fan turns off even with the temperature set in the high 60's - low 70's. The dealership service is booked out for several days and won't give me a loaner car unless the truck is undrivable. I'd rather not wait for the dealership. Anyone have any ideas? Truck has 650mi. I tried searching the forums but did not see this specific problem posted.
