I noticed that on hot days my AC is blowing out hot air. I checked it Tuesday and noticed the feel of the compressor coming on and the fan on the radiator turning on and it still blows out hot air. I have at times noticed the refrigerant pressure dropped a little bit and I know the Radiator hasn't been flushed and it has over 204,000 miles on it. And I believe it still has the original cabin air filter. Does anyone have an idea of what may be wrong with the AC system in my 2009 Ford Focus SE?

 

What were the pressures and at what ambient temp?

 

does the compressor click on for a little while than click off?
