Hot air underdash.

Well it’s been kinda warm around here but anyways when I turn my fan on and the air selector to cold, when I direct air to the feet only hot/warm air comes out the vents.

What could be causing this?

kind of a weird question but even when u put the selector on cold it wont blow in cool air if its hot outside and the engine is hot. try turning on the a/c then u might get some cold air. if thats the answer your looking for.

well I don’t have A/C but when I direst air to the front vents it comes out cool, only the foot well vents come out warm/hot.
