Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a dry area.
Disconnect the battery if electrical components are involved.

2. Inspect and Replace Seals

Door and Window Seals
- Inspect seals for cracks or brittleness.
- If damaged, remove old seals using a trim removal tool.
- Clean the surface area with isopropyl alcohol.
- Install new seals, ensuring proper alignment and adhesion.
Windshield and Rear Window Seals
- Inspect sealant around the windshield and rear window.
- If gaps are present, remove old sealant with a utility knife.
- Apply new automotive sealant and smooth it out to ensure a complete seal.

3. Clean Sunroof Drainage Tubes

Locate the drainage tubes at the four corners of the sunroof.
Use compressed air or a thin wire to clear blockages.
Ensure water drains freely through the tubes by pouring a small amount of water into the sunroof channel.

4. Inspect Cabin Air Filter Housing

Remove the cabin air filter cover, typically located behind the glove box.
Check for debris or blockages that could prevent proper sealing.
Clean the area and replace the cabin air filter if necessary.

5. Address Underbody Issues

Inspect for signs of rust or corrosion.
Treat any rust with a rust-inhibiting primer and repaint if needed.
Seal any holes with appropriate automotive sealant.
