    I have a 2007 which I bought used this winter. As the weather warmed here I noticed that the AC was blowing out warm/hot air. I took it in for an oil change when they topped off the coolant thinking that was the issue. It was ice cold for a few days and then tapered off which made me think that there is a leak that needs to be addressed. But then today I had the defrost on the lowest temperature setting and it was blowing out cold air consistently so is a leak now out of the equation? Any ideas what the culprit may be?

    Thank you.
