Noise when windy

[`08 Blue Crew]

First; my truck is a 2008 F-450 King Ranch.

When driving on a highway (60-70 mph) on a windy day I occasionally hear a strange humming noise kinda, like someone blowing into a kazoo. It isn't constant, it is occasional and short in duration. It sounds like it is coming from under the dash or near where the front windshield and dash meet. It is annoying


Any ideas?

I get that sometimes. The headwind has to be just the right angle, and I personally think it is my mirror(s). But dunno. It is annoying, indeed. Changing speed is the only cure I've found. Or a noise cancelling headset...!

My truck does it too. I think it's the trim around the windshield. It's always on the pass side to.
