Solution

1. Preparation

Gather tools and materials:
- Screwdrivers
- Trim removal tools
- Sealant
- Replacement seals (if necessary)
- Towels for cleanup
Disconnect the battery if working with electrical components.

2. Inspect and Replace Door Seals

Remove the door panel using a trim removal tool.
Inspect the door seals for cracks or deterioration.
If damaged, carefully peel off the old seal and clean the surface.
Apply a new door seal, ensuring it fits snugly and seals properly.

3. Check and Reseal Windshield and Rear Window

Inspect the edges of the windshield and rear window for visible gaps.
If gaps are found, apply a quality automotive sealant around the edges.
Smooth the sealant with a finger or tool to ensure a watertight seal.

4. Clear Sunroof Drainage Tubes

Open the sunroof fully.
Locate the drainage tubes (typically at the corners).
Use compressed air or a flexible wire to clear any blockages.
Test drainage by pouring a small amount of water into the sunroof channel and confirming it drains outside.

5. Inspect Cabin Air Filter Housing

Remove the cabin air filter cover.
Check for any signs of water accumulation in the housing.
Clean any debris and ensure proper sealing of the cover.

6. Verify Trunk Seals and Tail Light Assemblies

Inspect the trunk seals for wear and replace if necessary.
Check the tail light assembly for tight seals; reseal or replace gaskets if leaks are found.
