Some wind noise is normal. Before road testing the vehicle for wind noise, determine if the wind noise is more objectionable with the windows up or down, then proceed with one or both of the following road tests.

1. Road test the vehicle with one or more windows down.

1.1.	Road test in an area where there is little traffic and noise.

1.2.	Road test in all four directions: North, South, East, and West.

1.3.	Do not exceed safe and legal speeds.

1.4.	Road test at the speed the wind noise was heard.

1.5.	Tape over body seams and openings one at a time with a piece of 50 mm (2 in) wide masking tape until the noise goes away.

1.6.	Retest for secondary wind noise locations.

1.7.	Return to the repair facility and make permanent repairs using proper alignment techniques and sealing materials.

2. Road test the vehicle with the windows up.

The pressure relief valves are located in the door (coupe) or rear door (sedan) openings.

2.3.	Road test in all four directions; North, South, East, and West.
