I had this happening from my passenger area. Have noticed that if i loosen and re attach it will make some change in the sound.
Wouldnt bother posting something so simple, but I just noticed a couple of days ago that the passenger door molding was not in its proper place so not making the best seal. As I never sit in there, I never checked. So maybe something to look at.
behold a pale horse: and his name that sat on him was Death, and Hell followed with him...
