Windows all of a sudden fog up and auto control ratchet up to high for fan Why

What is your question?

The inside windows of a 2015 genesis fogged up and the auto control but sent the fans into high. Nothing could stop it until i pressed the manual fan button. Is this a symptom of a thermostat going bad?

What makes this problem better or worse?

better when i press the manual fan button and take it off auto.

How long has your 2015 Hyundai Genesis had this problem?

just started
