Hello Gentlemen,
I have not posted recently as I have fallen off a cliff of 'while you are in there' on my project Porsche 928. All the while, my Explorer rolls right along in daily driver duty.
I am posting now because the A/C has never been too enthusiastic. A couple of years ago, I put on a new compressor, receiver/driver, orifice tube, and all O-rings. It held a vacuum, and I charged it with the proper amount of R134a. It has not really lost any refrigerant since then.
The compressor cycles, I see decent hi/lo pressures on the gauges. However, the air from the vents never gets below 45 degrees. It keeps me from dying of heat stroke, but not cool.
I am theorizing that the recirculation door for the air distribution system is stuck open, or not being closed. Can I find said door? Of course not. I have looked through the factory service manual. I have done countless google and Explorer Forum searches. All I find are blend door fixes. I don't THINK I have a blend door issue, becuase the system shifts from heat to A/C just fine. Put the EATC controller to 90 degrees, and fire blows out the vents.
However, I am open to suggestion, and will take any advice...
Thanks!
