2014 AC vent door flutter noise?
I am the proud owner of a new used 2014 ZR1, 14,500 miles, manual trans. At 800 to 850 rpms, there is a "fluttering" noise coming from the left AC vent area (I think). It kind of sounds like an air flow door fluttering in the ventilation system. Any idea what this might be? And a possible fix? Thx, HappyGen06 updating to HappyGen07.

If the sound only occurs at a certain RPM, it doesn't seem like it would be a HVAC issue because the blower motor speed doesn't change with an RPM change as far as I know.
Also, I hope someone didn't pull one over on you saying your 2014 was a ZR1. The ZR1 came out in 2019; do you mean Z51?? Regardless, a C7, M7 with only 14,500 miles to start will be a fun driver!!
