I have a 2003 Nissan Primera 2L with what seems to be a belt noise when the A/C is turned on. The noise isn't really a typical high pitched squeal, but is very noticeable when the hood is lifted.

If I spray water on the A/C pulley, it significantly alters the sound, but doesn't make it go away completely.

The guy who's buying the car from me is very nervous about this noise, and wants me to take care of it, and I'm wondering if one there is really anything to worry about in the first place, and two if simply replacing the serpentine belt will take care of it, of if it may be that the belt is fine and maybe it's an issue with the alignment of the pulley itself?

Sounds like the clutch may be going bad in the A/C compressor. If it was slipping when engaged, you'd be hearing a terrible noise when the compressor is turned on, then water on it would definitely cause it to change in pitch. I don't know how you could test it, but I'm pretty sure if you remove the belt and then engaged the clutch, you could probably tell if there was an issue there.
