When I exceed 60mph I hear a hissing sound from the passenger side window as if you have havent closed the window propely, I have also installed window vents(see image below) for that sake, and have the windshield replaced (not because of this, but it was broken accidentally)
Still this sound doesn't seem to go, should I get the door rubber replaced? where could the air be slipping through?
PS: When I slide my hand along the window I cant feel any air coming in
