- Dust will leak into the vehicle where water will not.
This particularly happens in the lower portion of the vehicle's interior.
- Forward motion of the vehicle can create a slight vacuum which
pulls air and dust inside the vehicle.
- To determine the location of the dust leaks, perform the following
steps:
| • | Drive the vehicle on a dusty road. |
| • | Dust in the shape of a small cone or slit will usually be found at the
point of leakage. |
| • | Mark the points of leakage. |
| • | Shine bright lamps on the underside of the floor and cowl. |
| • | The interior should be darkened when performing this step. |
| • | Have an assistant check the inside of the vehicle for any points
where the light shines through. |
| • | Mark the leakage points. |
| • | Check the welded joints. |
| • | Seal leaks with an air drying, body sealing compound. |
