Bad A/C Noise

[383]

I have an '02 Tahoe, and the A/C is making an intermittent noise. The AC belt broke, and I assumed it was because the compressor locked up and took it to the mechanic. He found the compressor wasn't locked up, charged it some and put on a new belt. It still cools, and sometimes it will go all day with out the noise. It seems like the noise is more likely under acceleration. If I turn the A/C off, the noise goes away. Could it be a clutch problem, or is it the compressor, or something else? I recorded a video, nothing to see, but you can hear the racket it's making.

Sorry about that, think it's fixed. I forgot to mention that i replaced the idler pulley soon after the noise started, and nothing changed.

Noise is only with the AC on? If so, your comp. is toast, imo

 

You could watch the clutch plate while it is making the noise to rule out a worn clutch, but the belt breaking is a good sign your pump is done
