For 1990-2009 cars

1. Clean the weatherstrips and the contact surfaces using solvent.

Important: Ensure that the surrounding areas are free of chalk or powder.

2. Apply powder or chalk in an unbroken line to the contact surface of the weatherstrip around the perimeter of the following areas:

• | The rear compartment

• | The lid

• | The door

• | The door window

• | The hood

3. Close the panel completely without slamming. This presses the weatherstrip firmly against the mating surface.
4. Inspect the area of suspected windnoise:

• | The chalk or the powder line will be marred where contact is good. A corresponding imprint will be on the mating surfaces.

• | Gaps or irregularities in the powder or chalk line on the mating surfaces indicate areas with a poor seal.
