Drivers door wind whistle

GMC-Joey · May 1, 2016

Glad to be a part of this forum. Thanks to the members for all the information.

I have the noticed wind whistle at the drivers door near the side dash when driving over 70 MPH. More so in windy conditions. This would be hard to replicate as I believe it happens in combination of high speed and directional wind.

I saw two posts about this with no resolution. Any ideas about how to address this with GMC?

Yeah, I've noticed the same thing, but only with strong head winds.

I just turn the radio up

I had that issue. It ended up being the center light assembly.

There are numerous threads about this. I do not know how to link them, do a search and you will see lots of possible useful remedies.

Hope you get it fixed!

smith462,

did you have a dealer resolve this and if so do they have documentations as so I can relay to my local dealer?

thx!

I just read a complete thread about this. The resolution seemed to be the antenna. Maybe check into that and see if it goes away.

I used painters tape to find my whistling. My dealer was great! When I told them I finally found it, they just replaced the light assembly and all was fixed.
