2007 Kia Sportage Question: noisy AC compressor

Noises from the drive belt area can be difficult to locate without seeing and hearing the noise. It may be the compressor or the compressor clutch, or one of the drive belt idlers, but it will have to be inspected to know for sure. Let me know what you find!
