Inspection and verification
1. Verify the validity of the customer's complaint by using systems.
2. Check visually for obvious signs of mechanical or electrical damage.
3. If an obvious cause for a reported or received complaint is found, correct that problem (if possible) before proceeding to the next step.
4. If the cause of the complaint is not obvious, clarify the symptom of the malfunction and refer to the Symptoms Table.

When checking for dust penetration and water leaks, consider the locations of the sealant. When the vehicle is moving forward, any unsealed small openings in the lower section of the body allow air and dust to enter the body. When the ventilation ducts are opened, these pressures are equalized. Dust accumulates in the openings of the body in the luggage compartment area and can penetrate into the luggage compartment.
To eliminate dust penetration, pinpoint the exact area through which dust is penetrating. Under certain conditions, water can also penetrate the body at any point through which dust is penetrating.
To accurately determine the area where dust is entering, it may be necessary to remove the following trim panels from the vehicle:
- Door Threshold. For additional information, refer to Section 501-05.
- C-Pillar Trim: For additional information, refer to Section 501-05.
- Rear seat back and frame, and rear seat cushion and frame. For additional information, see Section 501-10.
- Luggage compartment floor covering
- Spare wheel
- Sliding roof hatch.
Once the trim panel(s) are removed, the location of most leaks will be obvious. Dust intrusion is usually indicated by a buildup of dust or sand. Isolate these areas, then road test the vehicle on a dusty road to ensure that all dust intrusions have been eliminated. A suitable leak detector can be used to locate dust intrusion, wind noise, and water leaks.
After the road test, check for dust deposits around the door openings, the side hood trim panel, the lower portion of the trim panel, and in the luggage compartment.
Sometimes leaks can be identified by shining a bright light on the underbody of the vehicle, if the above components have been removed, and inspecting the interior of the body joints and welds. A bright light will reveal leaks.
