Hey all, Maybe someone can shine some light on this for me before I take the truck to the dealer. As of late, and almost everyday, I've been having A/C problems. Here's what it's doing. I can turn it on to either, 1,2,3,or 4 and it'll blow fine but out of nowhere it will stop blowing all together. But here's the catch, it'll only stop blowing if set on 1,2, or 3 but will blow full blast if I turn it up on # 4. I believe that even if I tried turning off the A/C button and changing it to heat it won't blow either. (Not sure, don't remember). It's happened at any givin' time,. After starting truck, while driving, etc. Tonight for instance it did it again. When it did start blowing on the lower numbers, it would even stop for a second then start blowing again. I'm lost with it. Anyway, I'm trying to hopefully get some insight on the possible problem because I know for a fact that more than likley when I bring it down to the dealer, if they can't replicate the issue they will just tell me that there is nothing wrong even when I know that there is!
