Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Door Seals

Remove the interior door panel:
- Use a trim removal tool and socket set to detach screws and clips.
Inspect the rubber door seals for cracks or brittleness.
If damaged, remove the old seals and clean the surface.
Install new door seals, ensuring they fit snugly.

3. Clear Sunroof Drains

Locate the sunroof drain tubes (front and rear):
- They are typically found in the corners of the sunroof frame.
Use a flexible wire or compressed air to clear any blockages in the drain tubes.
Test the drains by pouring water into the sunroof channel and ensuring it drains outside.

4. Reseal Windshield

Inspect the windshield adhesive for gaps or deterioration.
If necessary, remove the windshield using a glass removal tool.
Clean the bonding surface and apply new windshield adhesive.
Reinstall the windshield, pressing firmly to ensure a proper seal.

5. Check Cabin Air Filter Housing

Locate the cabin air filter compartment, usually behind the glove box.
Remove the filter and inspect for moisture or debris.
Clean the housing and ensure the filter is dry before reinstalling.

6. Clean Drainage Holes

Inspect the undercarriage for clogged drainage holes (typically located near the firewall).
Use a vacuum or compressed air to clear any debris obstructing the drainage holes.
