2002 A/C questions
Folks
I have a 2002 F-250, CC, 4X4, V-10, with 175,000. During the very hot afternoons the A/C quits cooling for a few minutes. It will start bak up again and will work great. On the not so hot afternoons and the cooler mornings it is not a problem. I have never pulled over when it wasn't cooling to see if the compressor was on or off.
Any ideas before I pay the big A/C shop guys?
Thanks in advance,
Lee

I wonder if it's just working way too hard and it went over-pressure?
Did you check the condensor in front of the radiator and make sure it's clear of dirt/debris?
And what setting do you have it on? AC or Max AC?

Ac
Max AC and all is clean in front... I don't know about pressure. It can't be low on freon and work most of the time can it?

It very well could be low on refrigerant. As the system pumps the refrigerant around, there is a low-pressure switch, and a high-pressure switch. Working too much, the low pressure side may drop below the low-pressure cutoff. Or, there's too much refrigerant and the high-pressure cutoff is kicking in.
Without pressure gauges and testing it when it's failing, you could throw new pressure cutouts on it, but that's wasting $'s in my opinion especially if you can't check how much refrigerant is in it by checking the operating pressures.

Since it cools good when it works, your refrigerant is likely OK. You have symptoms of the clutch air gap having worn too wide.
The quickest, easiest check to make is located in this thread:

It won't cost you anything to try, and it fixed mine for four years, now.

wAht the pressures should be requires more knowledge of AC systems. As the ambient temperatures change, so does the pressure within the system. There are charts that tell you the target pressures for a given temperature.
