A/C "Rattle" noise when idling - '04 3.7

[Z00KA]

For the last 6 months, when I turn on the A/C, I'm getting a "rattle" sound when idling, but when I increase the RPM's, the sound subsides.

Popping the hood and it sounds like it coming from the A/C clutch.

A common problem on a KJ with a little over 100K on the odometer?

Fixes?

Thanks,

Joe Blanchard

I had a similar problem. I thought it was the a/c compressor but It turned out to be the idler pulley right under the compressor.
