Whistle when window down

[wreedps]

Hey guys I have a 05 Tahoe and when I roll the drivers window down I get a horrible whistle. I have tried to locate it while driving and have been unsuccessful.

I do not have any vent visors or anything of that sort, all stock.

Any ideas?

Shot in the dark, but maybe checkk your door seals??

i had this happen on a previous Yukon and have noticed it slightly on the hoe i just picked up. Come to find out it was my mirror. I guess over time the wind found a way to sneak through the gaps/cracks on the mirror. That could be your issue. I ended up having to replace the mirror and the whistle stopped with the new mirror

Yes I was thinking the mirror also. I will give that a try.
