- Dust will leak into the vehicle where water will not.
 
This particularly happens in the lower portion of the interior.
- Forward motion of the vehicle can create a slight vacuum which
pulls air and dust inside the vehicle.
 
- In order to determine the location of dust leaks, perform the
following steps:
 
| 3.1.  | Remove the mats from the floor. | 
 
| 3.2.  | Remove the mats from the toe panel. | 
 
| 3.3.  | Remove the insulation from the floor. | 
 
| 3.4.  | Remove the insulation from the toe panel. | 
 
| 3.5.  | Drive the vehicle on a dusty road. | 
 
| 3.6.  | Examine the interior. | 
 
Dust in the shape of a small cone or slit will usually be found at the
point of leakage.
| 3.7.  | Mark the points of leakage. | 
 
| 3.8.  | Shine bright lamps on the underside of the floor and cowl. | 
 
The interior should be darkened when performing this step.
| 3.9.  | Have an assistant check the inside of the vehicle for any points
where the light shines through. | 
 
| 3.10.  | Mark the leakage points. | 
 
| 3.11.  | Check the weld joints. | 
 
| 3.12.  | Check the body mounts. | 
 
| 3.13.  | Seal leaks with an air-drying, body-sealing compound. |
