Most likely your problem is the compressor control valve. Cost for a new one is abot $30. This is the most likely culprit based off of your described symptoms. Dealerships will want to replace the compressor, point out that this is a common problem with the Ford 500. A new control valvve is much cheaper than a new compressor.
where is the compressor contral valve? Napa says that don't see that part for my 2005 ford 500.

Mine too!! same exact thing. Can anyone help? My email is
My air conditioner on my 2007 Ford 500 blows warm air the minute I slow down or stop. What is wrong?
I had the same problem..had to replace the compressor. Luckily, I work at the local community college and labor was free. Hopefully you have a similar program where you are..Know the air is working fine
I have an 05, mine started doing the same. A friend is a mechanic, he says it's the compressor. Apparently it's a problem with this compressor in these cars. To replace the compressor will cost $700 for part, not including labor. He drained the Freon and recharged it, said that will hold me for a while. I just make sure I rev it up to about 2000 RPM for a few seconds and that seems to help.
My compressor was bad too, same exact issue, blew warm at idle. Rev up to 2000 -3000 rpm and it blew cold.
Have mechanic check for leaking air compressor "O" ring seals.
