Recirculate Whistle

So I just bought a new 2018 2500 diesel. At 500 miles the max A/C and recirculate started whistling. Took it to dealer. They took the dash apart. Said they fixed it. Picked it up yesterday and it’s still doing it. Already asked them to replace two trim pieces they damaged taking it all apart. It’s a new truck with 600 miles now and the dash has been apart. Anyone else experienced this issue? I’m pretty upset that this has already happened this early on.

yep. 2014 and mine does it too but only over 75 mph so I just decided to not use the recirculate button at higher speeds unless the radio is turned up. Guess its a known issue with lack of sealant but requires the dash to be pulled apart and I didn't want rattles in exchange for the slight whistle.

Damper doors are misaligned or need replacement.
