[V8] AC compressor noise- help

[Buchholz, Steven]

... does this mean that the noise does not switch on and off with the compressor?  If that is indeed the case the problem may be with the accessory (serpentine) belt or another bearing.  

AFAIK both my V8s are running with the original A/C without service as well ...
