2004 Thunderbird high speed air flow vibration noise

[jamit]

I just purchased a 2004 Thunderbird in Flordia with 66,000 miles. While driving back at 70 plus mph to Denver Colorado during hot sunny days over 85 degrees I'm getting a vibration noise that is due to the airflow. I know it is airflow because when I hear the noise and then change lanes behind a large truck the noise stops. When I pull back into the open lane the noise comes back.

Have others experienced simular issues?

Check your cabin air filter for loose or missing retainers. The rubber seal must rest against the windshield or you will get the noise you describe.

Cabin Air Filter Seal

Thanks for the reply. When i picked up the car I checked to see if the Air Filter was replaced. It was however I didn't check to see if it was installed with the clips. Great Catch!
