Now I know I just read about this a couple days ago and people havein issues with the ac or somethin. Well I go out to my truck this afternoon and turn the ac on cuz it was a lil warm in the truck and the friggin thing sounds like its gonna blow up.....Must be a bad fan or sumthin it shakes, rattles and DRIVEIN ME NUTS!! So now its off to the dealers for a lil warrenty coverage.....

 

my friends' 06 did the same thing. I got in it to go to the store, it started shaking, vibrating the whole truck, and it wouldnt blow anywhere near what it was supposed to! yep, its at the dealer right now for the same thing as you it sounds like! at least its all under warranty though.
