ISSUE: A "whistling" type windnoise from the fixed antenna mast may be caused by the base shape and size of the antenna mast. This usually occurs when the vehicle is driven at 60-65 MPH, (96-105 km/H) with crosswinds of 12-18 MPH, (19-29 km/H).

ACTION: Use the following service procedure to see if a new service antenna mast is required. The new antenna mast has a vinyl sleeve to reduce windnoise.


1. Remove the fixed antenna mast.

2. Test drive the vehicle to see if whistle is eliminated.

3. If whistle is gone, install a new service black antenna mast (E9SZ-18A886-A).


4. Tighten lower antenna mast to 3.5 to 5.5 N-m (31-49 lb.in.)
