2105 Enclave - Sunroof noisy above 55MPH

[IrvSp]

Live in Fl. and we can finally start using the sunroof. Almost impossible when we drive about 55MPH. Noise is deafening.

I've had cars with Sunroof's before and been in others as well. Not a problem.

I suspect a 'missing' part. There is a 'flap' that does go up when the roof is opened. Doesn't go much above the roof though and has a few oval slots in it. Suspect there should be another part there that goes in those slots.

Does anyone who has an Enclave with a sunroof have something different that what I have? That is something without the oval slots?

If someone also had noise how did you solve the problem? I see 3rd party wind deflectors sold, do those work?

Yep, opening the sunroof with no windows open is making the car into a giant ultra-low-frequency "whistle". I find that you have to open a rear seat window on one side, and/or a front window. Whatever you do, make the windows asymmetric, i.e. different on each side of the car.
