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?
