Wind Noise

[CRA]

Hi All:

I have a new(used) 2500 HD Denali. When I am on the highway occasionally I get a whistle noise coming from either the window or the door area. This is especially noticeable in windy conditions. Dealer can not find anything wrong. Does anyone have this issue to?

You're going to have to find it, and see what's up, tell us what you find. Could be just the weatherstripping, or an out of alignment door, I dunno.

Same here. I haven’t found my noise either

I have 2020 with similar.  Last week I took 2 rolls of tape and stethascope and hit the interstate for some trial and error.

 

I sealed the door/tow mirror interface with one wrap of electrical tape that got most of wind noise.  Doesnt look as bad as it sounds.  I've read some dealers are installing 2 gaskets there.  I ordered some .6"  and some .9" rubber o ring stock for permanent.

 

Still had a whistle which I traced to where the vertical and angled line of front edge of driver side window meet.  It was not a leak but turbulence.  Rigged a 1"x1" piece of gorilla tape stuck to black triangle trim on outside so that tape just extends over that joint and past it about .5" 

 

These two things eliminated maybe 75% of noise.

If it's REAL windy outside you are going to get either a high or low pressure area outside of your windows depending on wind direction.  It's flexing the window frame.  If that's the only time it occurs then you don't have a problem.  If it happens all the time then you need a weatherstrip adjustment.

Check the door pillars and make sure they aren’t lose at all. VERY common on 2015+ For them to come lose up at the top. Wind will push through it while your driving and cause a whistle. The glue they used to attach the clips pops clean away from the plastic. I repaired mine by using 3m double sided auto tape. It has a thin foam in the center and grips well. I haven’t had the problem since.
