My '97 Silverado Z-71 is making a noise like loose marbles from what I believe may be the A/C compressor. In addition, the engine seems to whine with the revs, whenever the fan is on - even with A/C off). When I turn the system to "off" both the marbles and the whine stop. The A/C blows cold still.

I was going to run it until something went, but decided perhaps something can be fixed instead of replaced after failure. I don't want to pay big money!!!

Thanks
