    Clean the weatherstrips and the contact surfaces with cleaning solvent.
    
    
   
   
   
    
     
      
       | 1. | Apply powder or chalk in an unbroken line to the contact surface of the weatherstrip surrounding the perimeter of the suspected areas.

       | 2. | Close the panel completely without slamming the panel. Closing the panel completely presses the weatherstrip firmly against the mating surface.

       | 3. | Inspect the applied line on the weatherstrip. The applied line is marred where contact is good. A corresponding imprint is on the mating surfaces.

       | 4. | Gaps or irregularities in the powder or the chalk line on the mating surfaces indicate the areas with a poor seal.
