whistling sound while driving on the highway

I have a automatic v6 05 taco and when I am traveling on the highway I can hear a low whistling sound while driving. It only happens in high gear on the highway. My acceleration also seems a bit sluggish. Any ideas?

 

Could be coming through your windshield there is a tsb on it they would have to reseal it and you won't hear it anymore

The front end noise I'm hearing is not necessarily a whistle, but more like someone blowing into a big empty jug. This low-pitched noise came from the right side of the dash. On the left side from direction of the speedometer, the sound is higher pitched, more like blowing into a soda pop bottle. If anyone ever did either of these things when they were kids, you know the sound I'm talking about. And yes, it will drive you insane! The dealership has also not located the source of this sound either.
