I have a 2006 toyota corrola. The airconditioner works, the fan runs great, but the air is warm. I had a shop check the freon and it is good. What else could the problem be?

What is your question?

Can this be an easy fix or do I need to take it to an expert?

What makes this problem better or worse?

If youo put freon in it, it is cool for about a day, then blows hot air.

How long has your 2006 Toyota Corolla had this problem?

a month or 2
