Air conditioning just stopped working

Hey all, I did a search on the forum for A/C problems and didn't find any relating to my problem. I have a 6.4 and the air conditioning just stopped working. It worked fine on the way to work. On the way home it was blowing warm air. I don't even here the compressor kick on when I hit the AC button. I checked all the fuses that I thought were related to A/C system, but didn't find any that were blown. Anyone have any other ideas for easy things to check? I know there are a few relays in the fuse box, but don't know how to check them....Btw, I'm new here, so go easy on me if I sound ignorant

Thanks for any help and sorry if I posted this in the wrong section

It could be the module/control panel inside the cab. My '06 panel sometimes completely dies and will come back on after turning the lights on and off several times.

You mean like a loose or bad connection behind the panel?

I think there is something inside the module that's faulty and turning the lights on and off has something to do with the display and making it work again.

Hey thanks... I'll take a look around and see if that has any effect on it.

Did you ever find a solution to this? My truck just did the same thing. It only has 67,000 miles on it. Seems like a little early for a compressor to me.

2008 F350 6.4 King Ranch, Custom 6 door conversion to fit all the rug rats, 6 inch Procomp lift, 20x10 KMC Diesels, 37x13.50 Toyo Open Country MT's, SCT Programmer and more to come
