Flapping Noise

[bigslammy]

I have a 2005 1500 reg cab normal a.c. ,I have a flapping type noise when I accelerate mainly cooler weather . Doesn't do it normal driving like going down the road . Can't tell where its from sounds like center of truck maybe engine compartment are easy . Any ideas ?

Does it happen when your not moving? Might check the condition of the belt. I would start with simple things first like missing fasteners in plastics.
