Got a question for you all. Have a whistle sound that starts around 35 mph, and it is not the turbo whistle. Hear it when just coasting, no gas applied at all. Can hear it with windows up even, radio down. Anybody else have this???? Started recently, just have not had a chance to take it in yet... Have to go for oil change next month, so figured I would have them look then...

HVAC on or off?
I have an inconsistent whistle that is 100% HVAC related. Turn it off when I hear it and back on and it's gone.

ocwill1

both... when window open, off, when window closed, on.. I thought the same thing as well.. I have the slim line window vents, but I have pressed on them while driving in different spots and still hear it..

Hmmm ok. I'd check door gaps/seals and the windsheild. Has it ever been replaced?

ocwill1

no replacement.. truck is less than 1 year old, only around 7800 miles..

Been a lot of complaints of whistling with those installed.

I had the black OEM with the f150 logo on it and it whistled right around 35 to like 45 mph

I have an AVS bug deflector and it whistles starting at about 30-35.
