So I recently picked up a 94 2500 3/4 ton. The serpentine belt went on me yesterday. No biggie. Replaced it in under an hour, no blown head gaskets, starts and runs like a champ. But my AC is giving me issues. The plug is loose so when I have it on full blast and hold it down, my belt starts to squeal, the clutch plate barely spins, then stops, and I saw a little puff of dust/smoke come out from it. I am assuming the clutch is shot but any advice would be really appreciated, thanks!
