New HVAC Noise
When my HVAC is set to 84 degrees and auto fan mode and center dash and floor vents selected, hearing a constantly / continually changing whirring sound, a fan / distribution like noise that gushes and then stops.
Happens one way for a bit and then the other way for a bit and back. When it gushes sounds as if a flap is opening and dumping through a different distribution vent, but the air flow remains the same out of the vents no matter which sound is happening. Sound is emanating internally.
Having difficulty capturing the sound on video, as noise is coming from behind vents / within dash, and placing camera near vents picks up the air flow volume.
Any thoughts?
Thank you very much.
