I think the seal or door frame is just badly designed based on the fact that I had this noise on both driver and passager side.
It’s been two weeks that i did my fix and I had strong face and side winds running over 100km/h without noticeable noise coming from the upper window B pillar...
Here’s how I fixed my noise issue on my truck
The whistling noise was coming from the opening inside the window door frame upper corner in my case. This was on both doors. 5mins to fix per doors, but months of annoying noise.
I use 3m Calk strip. Can be bought on amazon.
If you don’t know this...
