I have a 2014 Street Glide ...whistling comes from the right hand side of my air vent. It starts at about 45 mph and continues to get louder until about 60 miles per hour. Turn the vent off and noise goes away. Cover the right hand side of vent with my fingers and noise goes away. Cover the left hand side or middle and noise does not go away. Am I the only one with this noise?

 

I have never had that problem before, is there any debris stuck in there? There is also a seam down in the vent maybe something isn't aligned correctly causing the whistle.

 

we have read this problem on here several times some dealers are replacing vents. Take it into dealer and show them. Mine did it one time and I open and close it few times and it stopped and has never done it since.

 

Mine does it from time to time, but I've only noticed it when it's very windy out. I think it whistles when a crosswind hits it just right. I've heard it probably 3 times all summer.
