Solution

1. Preparation

Gather tools and materials: vacuum, towels, water, and a flashlight.
Disconnect the battery to avoid any electrical issues during repairs.

2. Clear Sunroof Drains

Locate the sunroof drain tubes: They are typically located at the corners of the sunroof frame.
Pour water into each drain to check for flow. If water does not exit under the vehicle, proceed to clear the blockage.
Use a flexible wire or compressed air to clear any obstructions in the drain tubes.
Verify drainage by pouring more water and ensuring it flows freely outside the vehicle.

3. Inspect and Replace Door Seals

Visually inspect door seals for cracks or wear.
Remove the old seals by gently pulling them away from the door frame.
Clean the area of any adhesive residue.
Install new seals by pressing them firmly into place, ensuring a tight fit against the door.

4. Examine and Repair Window Seals

Inspect the windshield and rear window seals for gaps.
If needed, apply a sealant specifically designed for automotive use to any compromised areas.
Ensure the application is even and allow it to cure according to the manufacturer's instructions.

5. Clean Cabin Air Filter Housing

Remove the cabin air filter cover located under the dashboard.
Check for water accumulation in the housing.
If water is present, dry the area thoroughly and inspect for blockages in the drainage hole.
Replace the cabin air filter if it is wet or damaged.
