My heat blows out cold air. It was blowing out hot heat, then all of a sudden it was cold.

What is your question?

I was sitting in my car, with the heat on and it was HOT! So I changed the temperature from 90 to about 75 (has the dial knob) when I went to put it back on 90, it started blowing cold air. We already checked the antifreeze, and it was good.

How long has your 1996 Toyota Avalon had this problem?
