2017 Explorer - Intermittent howling sound

[cell0phane]

My 2017 Explorer started howling in cold weather (-10C) 3 years ago. It continued through the spring and summer last year. The local mechanic and Ford cannot find the issue.
It happens frequently but not all the time. Usually around 40kmph, or 90-110kmph. The howling is sometimes the same, it happens when slowing down or accelerating.
My mechanic suspected it was the serpentine belt, so that was replaced. A wheel bearing was suspected and one wheel bearing was replaced recently. It happens on both summer and winter tires with different rims.

I think the wind is getting caught somewhere but I can't figure out where or what to look for or even how to look for it. I had the windshield washer tank replaced last August and it stopped after that but started up again a month ago.

Any ideas whatsoever? I enjoy the vehicle but it is driving me crazy. The garage and Ford won't look at it anymore even after hearing the sound since it doesn't cause driving issues.

Sometimes the cowl that runs along the outside of the windshield can cause this kind of sound. You can try taping it down. Some members had noticed the end corners were not snug.

That cowl is crazy expensive due to the shipping charges. If tape works, think I'd sooner try a sensor safe (non-acid cure) RTV to hold it down onto the windshield before replacing it... can always do that later if the RTV doesn't hold long enough.

I put black gaffer tape around the entire front window and the howling is completely gone! I really appreciate the help. Not sure why the shop couldn't find that or suggest that.
