2004 EB 4.6 Explorer A/C Turns off & Back On at Random

[cantornikolaos]

In November, 2016, I got a new compressor installed. It worked flawlessly until just now. One day, about a year ago, it wouldn't turn-on. I didn't have pressure guages with me in Milwaukee, but I checked fuses/relays and no dice. At the end of the day, it magically started working again and worked flawlessly until last night. I was returning from a road-trip to NY, and as soon as I crossed the SC state line, it started blowing nasty, warm, wet air at me. Also, traffic on I-85 came to a halt shortly after. I hate this place, and I think it hates me back.

I checked the relays and fuses. No dice. I know there's Freon (R-134a) in the system, but I don't know if it's fully charged. Before it stopped working last night, there were no unusual noises. Today, I called a few places to get quotes for a diagnosis. The shops I called wanted to do unnecessary work and change an ungodly rate. After I got off the phone, it started working again, as if by magic. It worked great all day. Now, it is back at its old game of not turning on. I was driving and the system was working. Without any warning or unusual noises, It stopped. I again noticed warm, sticky, wet, nasty air blowing into the cabin.

Has anyone encountered this? If so, what is the culprit?

Thanks!

This was happening with my 2002, turned out the Freon was low. Charged it up to spec and the AC is working fine.
