clicking noise when a/c compressor is engaged
I replaced serpentine belt about 500 miles ago. All pulleys were smooth and quiet. i noticed today a clicking sound that changes with engine speed only when a/c compressor is engaged. A/c works great as it always has. Anyone else have t his experience?
It doesnt sound like a bearing, its not whining or crashing. Its a light ticking that can only be heard outside the car.

The sound maybe nothing serious, but it also could be the compressor is getting ready to crap out...
Have you ever had to add refrigerant?..a possibility could be you need a few oz's of refrigerant oil added, which can be loss during any leaks..a couple of oz's should be enough to quiet it down,,,but even at that, the compressor may have been harmed by running on low oil...If you do add any, just be sure it's the right kind of oil...I think your MY is set up for R-134a, so you'll need PAG oil.
Oh, it also could be the Compressor clutch assy.

I've done some quick searching and it looks impractical to buy a clutch without compressor and looks impossible to install a clutch on the vehicle. So, looks like a new compressor when she finally gives up. Thanks for your help.
Can't complain. In the miles I've driven it I've done intake and IMT seals, plugs, normal maintenance and a thermostat. It's been a peach!
