I have not had the issue, I have had the auto climate control blow hot air like mad after turning on the car though. Was used to climate control not allowing hot air flow if the temp of that air is below the selected temp. The car would wait to aggressively send air out until the hot air was vented out. Same goes for cold air in the winter, the car will not freeze you out, it will wait until warmed up and an offer the right temp.
