Sub-steps:
1. Open all doors and visually inspect the rubber door seals for any tears or gaps.
2. Use a flashlight to check for any signs of water ingress around the seals.
3. If damaged, remove the old seal by carefully pulling it away from the door frame.

5. Install the new seal by pressing it firmly into place.

3. Check and Repair Windshield Sealing

Sub-steps:
1. Inspect the windshield for any visible gaps or deterioration in the sealant.
2. If present, carefully remove any loose sealant using a plastic scraper.
3. Apply a high-quality automotive sealant around the edges of the windshield.
4. Smooth the sealant with a finger or a sealant tool to ensure an even finish.

4. Clear Sunroof Drains

Sub-steps:
1. Open the sunroof and locate the drainage holes at the corners.
2. Use a flexible wire or compressed air to clear any blockages from the drains.
3. Test the drains by pouring a small amount of water into the sunroof channel to ensure proper drainage.

5. Inspect HVAC Drain Tube

Sub-steps:
1. Locate the HVAC drain tube, usually found under the vehicle near the firewall.

3. Ensure the tube is securely attached and not cracked.

6. Dry and Clean Interior

Sub-steps:
1. Use towels or a vacuum to remove excess water from the carpets and upholstery.
2. Allow the interior to air dry completely to prevent mold growth.
