A/C pulley chirp?
I have been chasing a squeaking sound for some time so I replaced all the pulleys on the A&A procharger bracket and that helped. The pulleys were a bit old so it needed done anyway.
I have since narrowed it down to the AC belt etc. Pouring water on the ac belt will kill the sound. The belt isnt very old and I replaced the pulley on the tensioner a little ways back. It is likely the idler pulley which is hard to get to without pulling the blower but that happens.....
I was thinking it could be:
The idler pulley (most likely)
The belt itself
Or possibly a bearing etc in the actual ac compressor? Is that common?
Car has 68k miles on it.
I guess I plan on replacing the pulley and belt while i'm in there but was curious about AC compressor bearing etc? I really don't want to pull that.
Thanks in advance.

Does it make sense that water will kill the sound but when i tried a little WD 40 last night it was still there or maybe worse? Granted I may have got it on both sides on the belt because I had to spray from underneath when I was changing the oil.
