I don’t drive on the highway that much, but I’ve noticed the wind noise has gotten worse over the years. Seems to be mainly from passenger side. Would this be the door seals or the window/belt trim? Any ideas on quieting it down.
Check your windshield seal. Push on the glass and see if it moves. I replaced all of my door weatherstripping trying to get rid of some of the highway wind noise. It helped but it wasn’t until another 80 owner suggested the windshield seal. I haven’t replaced it yet but if I push on the glass while cruising on the highway it all but disappears.
