When the A/C clutch is engaged, I get an odd irregular noise that sounds like a bolts bouncing in a can. A/C seems to work fine....the noise doesn't seem to be related to engine speed...there appears to be some metal shavings sitting around that would need to have come from between the belt pulley and the compressor. With the serpentine belt removed, I don't feel any rough motion on the belt pulley or while turning the compressor by hand. I consider removing the A/C clutch to get a better look...is this feasible while the compressor is in the vehicle?? Any other thoughts??? Thanks...
