With all due respect to your service writer friend, please ask him this, as these also "could" be the problem.
Possible problem with the TEV valve clogged or not opening up enough. If this truck does not have a TEV, then could the fixed orifice be partially clogged?
Can any of the mix doors not be opening or closing properly?
Is there a partial blockage of the evaporator coil?
Is the heating water supply valve to the heater closing completely? If there is no valve, is the door closing tightly?
And on and on. It is probably something oddball, but the questions I asked are all problems I have seen on different vehicles. And they were a bitch to diagnose.
I'm not pulling this out my butt. See previous posts.

I have read this entire post through TWICE, and I must say that I am wondering why one vehicle works and the next one does not.
It got my curiousity up enough over my wifes 2010 White Lariat, with tinted windows, and the 5.4 V-8, 4 X 4, that I got a thermometor, put it in the vent and took it for a 22 mile trip.
Below, I noted the outside temp, the inside temp, the speed on the highway, and the humidity at the time.
I fully intend to try the test on my 2002 King Ranch 4 X 4 as well.
Here is the findings of a short trip with my wifes truck.
Outside temp: 95*
Humidity level: 38%
Inside temp at the vent: 40*
My service writer friend, said that IHHO, the following "could be the problem".
1) Undersized compressor
2) Lack of freon
3) Bad sensor...............
ALL if which has been discussed in great detail here.
I will see what I can find out about the "specs" of the temps etc., from him and report back.
P.S. I am going to try my 1995 FORD Thunderbird too. Just for chits and grins !!!!!!

Thanks for the information. At 95F, your wifes truck does quite well to get down to 40F. Mine can barely do that at 80 or less and that is at the short lived low end of the spectrum.
This problem appears to hit trucks with manual A/C (like mine) and those with climate control. That tells me that the problem lies in a component that is common to both systems. I'm thinking contamination in the system or a sensor. Having the A/C go colder of stay down longer in the cycle would be nice.
I would also like to know if Ford uses the same manufacturer for common components.

Agreed. They only know - check pressure - check refrigerant level - run in a shaded spot - and say all is okay. I believe that they could fix these trucks if they made an effort to look for the problem.

Now you are hitting the nail on the head! As I have said, my belief is this centers around fuel economy!
We need a hack for the computer to control and change this, especially if Ford wont help us!

Additional info would definately be good to have. I'll tell you, I'd hate to see a couple of the guys who have looked at my truck get that far into its dash.
