'99 Mustang A/C not working - Ford Forums

I have a '99 Mustang 3.8L. The Air conditioning isn't working on it. I've checked the coolant/freon and it is fine. All that happens when it is turned on is it blows hot air no matter what the setting is. I think it is the compressor. Does anybody have any suggestions?

Im having the same problem with an explorer. Does the compressor turn on? also are you able to check for codes?
