The P0480 code popped up again. 6 months ago I had the same thing and they replaced the fan clutch. This time when it went, I was accelerating from a stand still in a school zone and turned on my AC during the 25mph drive. I noticed some lights flash in the dash and then I did not hear the fan. I got home and turned the key three times and saw the code. I am not to concerned, especially when I looked outside this mornig and saw frost on my hot tub.
I will get it in when I get my oil change next week. I am wondering if I have something else messed up that would cause the fan to go bad. Any inputs so I can look like a pro when I show up with my truck to have it looked at? Other then that, these trucks rock!!!!
