A/c Noise

[Highmiles]

Hey everyone,

 

I have a 03 2500HD 6.0 that just recently started making a clattering noise, only when A/C is on and only above 2000 RPM. Today I replaced the idler pulley, no change. Any chance that it is the clutch or other component making the noise, or do I need to replace the compressor. If so, should I replace the receiver/drier and condenser?

Anyone have any advice on where to purchase these parts.

 

Thanks in advance,

John

Do you hear the noise inside or outside more? sounds like a problem I have.
