I own a '04 Eddie Bauer Explorer, within the past several months I've noticed a strange noise under the dash. The noise occurs ONLY when driving 70+ mph down the highway and when there is a cross wind. The strange noise sounds like an air conditioner vent leak or vent that is exposed to outside air. It only occurs when a cross wind hits the vehicle. And it sounds the same as like blowing air across the top of a coke bottle. Has anyone else experienced this or am i just crazy (which Ive been told by my wife that I've this problem for more than several months)? I've not taken it in to the dealer because I'm afraid it will cost too mcuh to fix. Thanks for any help.
