2005 Trailblazer with whistling sound

My 2005 Chevy Trailblazer makes a cyclic low pitched "whistling" sound when the A/C is running. A/C still runs fine, air is plenty cold, no problems with the fan, just the cyclic sound that now occurs whenever the A/C is running. Any ideas what might be causing that?

I am sorry to hear that you are experiencing this issue. Have you spoken with your dealership to confirm what the noise could be?

Thank you

yeah, ya gotta make sure you get it into the dealership so they can sell you more repairs (that they typically don't fix)
