With no info on car year or make, it is necessary to guess. Many cars have a hot water shut-off when you do not want heat. that could be mis-adjusted, stuck, or broken.

If the weather is very hot, it can take a long, long time for all the plastic vents and tubes to cool down.

If no helpful answers appear, please more details on this page.

Also many cars use a vacuum controlled system to change the air flow. You may have a vacuum problem. We really need some additional information. Make model and year? Does it make any noise when you change any of the controls?
