I've got a 2018 GMC Sierra 1500 that has wind noise on driver's side. I just came out of the shop for the issue. Said the sealed holes in door with gap sealer, but I still have the noise. After examining, I noticed the window seal is not tucked under the mirror very tight, like the passenger side is. I believe the air is coming between the door and seal, as the way it is now, wind would catch the corner of seal.
Anyone know if the window seal is supposed to be between the mirror plastic and mirror rubber flap, or under both? I don't want to reverse engineer the passenger side and take a chance at screwing it up. My passenger side is under both. Curious if any others had to do this.
Thanks guys!
