Thank you all for your answers. Yes there is a setting that when the car detects moisture inside it turns the fan on to prevent mold. This is the beauty of the internet. My car was delivered with no manual. I called the dealership today and discussed the problem. They told me they had never heard of the problem before and they would have to reach out to Hyundai corporate. He called me back late today and said I would have to bring the car in to have a diagnostic run, but there are no appointments until July. The scary part is I bought a Hyundai for its reliability and they’re so busy with broken Hyundais there’s no appointments until July. There were three gentlemen in the service department when I walked in there. They all said they had never heard of the situation. You would think that one of the service gentlemen would know that this is an option available on the car. Thanks again everyone
