2016 Regular cab longbed 4x4 5.0L. I can hear a very distinct annoying whistle noise from the passenger side only when the window is down and speeds are between 47-60 MPH.

With the drivers side window down, passenger side window up, no whistle is heard t any speed.

I removed the right front fender radio antenna and the whistle noise is still there 47-60 mph. Tried folding in the passenger side door mirror and no improvement. Ideas? TSB?

Thanks - Ozz

If you have a short antenna, try removing it.

As I wrote above, the antenna was removed, same whistle issue

My driver's side tow mirror whistles really bad too. It is the pivot point where the mirror folds in. I need to bring it in to see if they can fix the problem. I have to have the radio on otherwise it drives me nuts.
