One nite my a/c stopped cooling. i cheked everything seeing if it was empty but it wasnt, lookin for a busted fuse but its fine. what else can it be?? and how do i fix it?
Could be pcv. this was a problem on 03 ford trucks. very easy to replace. can just replace the valve itself or the whole pcv kit. valve is 5 bucks, the kit is about 80 installed. you know if its the problem if you see "oil spray" around your vacuum lines. also, if you're truck runs a little rough from time to time.

I also have an F150 2003 Supercrew and my A/C will only cools and blows on Defrost! When it is on the other settings it just blows unconditioned air. So at least I can cool down the vehicle, but it won't blow directly on you.
I have the same problem on my F150 4x4 supercrew, blowing a.c. only from the defrost vents., and when release of gas goes back to the front vents.
