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.

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.
