Ac blows only hot air - Ford Forums

I have a 2000 ford taurus with climate control. No matter what the setting it will only blow out hot air. There are no leaks and the freon is fine. Even will not blow outside air, only hot!. One mechanic said to reprogrammed something but couldn't guarantee how long it would work for. It worked for a couple months blowing cold air but quit working again. Another mechanic said that was not possible that there was nothing to program. When the problem first happened I used to be able to play with the controls..... move the climate controls all the way up then down, on and off, and eventually the ac would kick in..... but not anymore..... just constant hot air. Help it is about to get hot here in houston

Sounds like a temp. blend door actuator. My 2001 Taurus SEL had the same conditions. If I set the ATC to around 70*F then left it there when I turned it off it would blow hot on the next start-up. I would start the diagnostic procedure then it would work again. I got the trouble code for the blend door actuator, and I eventually replaced it and fixed the problem. Fairly easy to replace, just remove the ICP (radio/climate controls) and the silencer panel under the R. side of the dash and you will see it on the side of the A/C box right in front of you.
