2003 Ex XLT At a idle the a/c blows warm. While driving down the road it is fine.
Work done: replaced blend door actuator, Orifice tube, accumulator and service port valve cores. Evacuated and charged with 56 oz of R134a.
Compressor seems to be running fine.
Any suggestions?
 






I just replaced the AC compressor in my Mountaineer due to it being worn and no longer working efficiently. This solved my problem completely. This video might help you:

Replace fan clutch. I got this one: More Information for HAYDEN 2776
 






I’d bet fan clutch too. I had the same issue with my 02. It had a new compressor for unrelated issues. I added an electric fan to the radiator with an on off switch. It solved my problem.
