Notice: The air hose test should only be used on fully cured urethane adhesive. Otherwise, damage to the urethane adhesive bead could result in additional leaks.

Exterior windnoise is louder when the vehicle is driven with 1 or more windows down. Exterior windnoise occurs when air passes over the body panels, the seams, or the openings. Use the following items during the test drive in order to aid in the detection of leaks.

1. While driving, determine the location of the exterior windnoise by lowering 1 window at a time. If the location corresponds with the condition in Step 2, pull over and make a temporary repair with the 51 mm (2 in) wide masking tape.
2. Tape over the gaps and the moldings 1 at a time. Test between each taping. Taping over the gaps and the moldings will correct the condition.
3. Temporarily repair the condition with the masking tape. Adjust the tape when needed.
4. Continue testing in order to determine if the noise has been eliminated or other leak areas exist.
5. When all the reported leak conditions are located, make permanent repairs using the proper alignment techniques and the sealing materials.
