Solution

1. Preparation

Gather tools: flashlight, trim removal tools, towels, and sealant.
Ensure the vehicle is parked on a level surface and the interior is dry.

2. Inspect and Replace Door Seals

Remove any trim panels around the door to access the seals.
Inspect the rubber seals for cracks or tears.
If damaged, remove the old seals and clean the area.
Install new seals by pressing them firmly into place.
Reattach any trim panels.

3. Clear Sunroof Drains (if applicable)

Locate the sunroof drain tubes (usually found at the corners of the sunroof frame).
Use a flexible wire or compressed air to clear any blockages.
Test the drain by pouring a small amount of water at the sunroof edges to ensure proper flow.

4. Reseal Windshield

Inspect the windshield seal for any visible gaps or cracks.
If necessary, remove the trim around the windshield gently.
Apply a high-quality automotive sealant to the affected areas.
Reattach the trim after the sealant has cured.

5. Clean Underbody Drainage Holes

Locate the drainage holes under the vehicle (usually near the firewall).
Use a wire or compressed air to clear any debris or blockages.
Ensure water can flow freely through the holes.

6. Check Cabin Air Filter Housing

Remove the cabin air filter cover.
Inspect the housing for cracks or improper sealing.
If damaged, replace the housing or reseal it with appropriate sealant.
