    OK, this is driving me crazy! My dashboard gets a high pitch squeal behind it when I hit highway speeds of 75 mph or more or when a gust of wind hits the truck. It sounds like when you blow on a blade of grass held between your palms; really loud and annoying. I know it has something to do with a vibration under the hood or in the dash.

    I tried to tape down the washer fluid cord to the underside of the hood in case air was vibrating that; no luck. Messing with the AC/Heater controls does nothing.

    Now, my wife refuses to ride in my truck on the highway as we delt with the noise today for 3 hours.

    Any ideas on the cause of this sound?
