repost of "2008 F250 Wind Noise" for 2011 and up too
All, I am reposting this from the Super Duty & Heavy Duty Forum. I have been trying to solve this problem for awhile now. Same issue on my 2011, so it is relevant to this forum too.
I am so glad I found this older post. This is exactly what was wrong with my truck, same side even. Talk about an annoying sound. Bringing current for others in case they have this same issue. Was getting ready for a long trip, and wanted to solve this. For now, just used some silicone seal on the loose seal. When I get back I may order these parts and just replace them more permanently than just the nylon push pins.
Finally! After months taping all around the windshield and cowling junction to no avail, I have finally found the source of my musical dash.

First the symptoms and observations:
1. The noise started at about 35,000 miles; First very infrequently then with increasing frequency.
2. The noise was always occurred by a crosswind (or when passing a semi) at 55+ mph.
3. The noise never occurred while it was raining.
4. The noise would stop if windshield washer was engaged for a few seconds (would come back after water was dried off).
5. The noise was always the same tone (never changed with speed or strength of wind).
6. the noise was always the same volume after threshold for tone was reached.
<O</O
First I tried taping the center junction of the cowling; next I taped the bottom of the windshield, next I taped the windshield sides, next I taped the top of the windshield. The noise still persisted. As I stated earlier, engaging the windshield washer would silence the noise; so I engaged the windshield washer until it stopped and the pulled over and observed which areas were wet. I saw that only the sides were wet so I started looking only in the side areas.
<O</O
On the passenger side (there is also one on the drivers side) there is an auxiliary door seal just in front of the main door seal that is held in place by press-in nylon body bolts/screws. I noticed that it was somewhat loose. Also I noticed a ~5/8 hole that went into the dash area that was covered by a plastic film. The air was rushing past the front edge of this auxiliary seal and traveling over this hole. When this air got strong enough it would vibrate the plastic film covering and act like a reed on a musical instrument. I pulled up this auxiliary seal and re-installed it. Now the noise is gone. That is music to my ears!
