REPLIES FOR BOTH POSTS: Not sure if the cooling fan is working. The air filter isn't blocked. Yes, water drips underneath when the A/C is used. There's around 135,000 miles on it and 90% of them are highway miles (if that matters). It is a "standard" Edge.

My air started blowing hot a couple of weeks ago. It has done this before (3 years ago), but it just needed more freon. My dad put in some freon, or we think he knew what he was doing. It blew cold air for a day, and then was hot again. I took it to a friend to check it out, and he determined it needed a new air compressor b/c of the reading from the machine he hooked up to it. Not wanting to take on that expense, I took it to another guy for a second opinion. He said there are no signs that my compressor is bad, but it sounds like a leak. After they got under the hood, they realized there was several years of gunk on the "screen" as he called it and they cleaned that out. He put freon in, and ran dye to see if there was a leak. He couldn't find anything else wrong with it. When I picked it up, he said he isn't sure what he did fixed the problem and that I might be back in a few days. Turns out that the air does get cold now, but it comes in phases. It will usually start off cold then gradually blows hot, and then gradually blows cold again. It's constant phases like that. Anyone else heard of these problems? Any idea what is causing this?
