Please discard PIT5291E. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition / Concern Some owners may comment when driving at highway speeds (60 mph and up) there is a wind whistle noise heard from the right or left rear quarter glass area. This noise may be more noticeable with a cross wind. This concern could be caused by either of the following: 1. The fit between the exterior “D” pillar trim and the rear quarter glass in the area shown below. Excessive urethane from the quarter glass installation may not allow the exterior “D” pillar trim to fit properly against the rear quarter glass, as shown below. 2. The gap between the rear tail light assembly and the quarter panel, as shown below. Recommendations / Instructions 1. Use a sharp knife and cut off the excessive urethane, as shown below. In most cases the urethane will need to be cut sub-flush to the sheet metal. This will allow the exterior “D” pillar trim to fit correctly against the rear quarter glass. 2. Install a 5mm X 5mm (3/16 X 3/16) piece of closed cell foam tape along the entire length of the tail light assembly, as shown below.
