I had the same thing back in March. Couldn't figure out for the life of me what was going on. Checked the weather stripping and everything was find there. Here's what I discovered, check your window and make sure it's going up all the way. When I would go to the car wash, water would get in the car when I would spray that side which was on the passenger front door.I found out that my window wasn't going up all the way which was a sign that the regulator was going out. Sure enough, it went out while I was home visiting in MS. It happened about two days before I had to drive back to the VA. Got the new regulator and put it in and sure enough the wind sound was gone and no more leaks when I would go to the car wash. So inspect your window and see if it's going all the way up when you roll it up.
