So on windy days at highway speeds get an occasional low/ mid frequency whistle noise coming from on top the cab, seems its from the cab marker lights - checked that they are tight, no leaks etc - Anyone had this before and were you able to stop it? Only thing so far is to reduce speed or not drive when the winds blowing hard.
Thanks

From your Garage pic, it looks like you have sun/moon roof. If so, any chance you're getting the wind noise from there?

It seems to be coming from in front of the sun roof....I don't ever open it for fear of leaks ( wish it wasn't there) .. but I guess its a possible source.. anyone ever have that noise from the sunroof?

EDIT - just to clarify this noise is not a woosh sound from a window or door not sealing - sounds more like a horn than a whistle, its a lower frequency sound than a window seal wind noise if that makes sense

+1 on the sunroof. If it is hot out and I tilt the glass, then I will get noise once I close it. All I have to do is slide it back a hair then close it back up. I think the seals or gasket swells in the heat. I use it all the time in both tilt and slide with no leak issues. Well, except for the one time it was cold AF and the drain tubes froze but snow melt had accumulated under the glass. But that is unrelated.
Anyway, try sliding the roof back an inch then closing it again.
