Customer may report hearing wind noise from the front door area when the vehicle is driven at highway speeds. After diagnosis, it is determined that the source of the wind noise is the exterior rear view mirrors. Possible sources of this wind noise are the seam surrounding the turn signal lamp and the seam surrounding the side assist lamp (if equipped). Because of the lack of two mounting screws from the mirror base to the mirror housing, the mirror housing can move when the vehicle is at speed, creating a large gap around the turn signal lamp. The modifications explained in the Service section of this bulletin will effectively mitigate the wind noise symptom should these seams be the root cause of the wind noise. Two additional mirror housing mounting screws are being installed in production.
