Wind Noise

Air entering or exiting the vehicle through small openings in the body can result in wind noise. Sources of wind noise are detected by driving the vehicle at highway speeds in four different directions. Listen for sources of wind noise with all windows closed, radio chassis (18806) off, A/C blower motor turned off and ventilation ducts open. A stethoscope can be used to pinpoint the source of the noise.

Most wind noise-producing leaks will occur at the door and window seals or at sheet metal joints in the door or the door opening in the body.

Seal all leaks with RTV sealant and foam tape or by repositioning or replacing the seals. Road test the vehicle to make sure all leaks have been adequately sealed.

An alternate method of verifying corrective actions involves the use of Rotunda Ultrasonic Leak Detector 029-00001 or equivalent. After identifying the leak point through a road test, obtain a meter reading by using the leak detector. A check with the leak detector after repairing the leak will verify the effectiveness of the corrective action. A final road test may still be advisable to make sure that other objectionable leaks, not noticed because of a major leak, do not exist.
