Solution

1. Preparation

Gather tools and materials: flathead screwdriver, vacuum, towels, sealant, and replacement door seals or windshield adhesive if needed.
Ensure the vehicle is parked on a level surface and the interior is dry to facilitate inspection.

2. Clear Sunroof Drains

Tools Required: Hose or water bucket
Pour water into the sunroof tray to ensure the drains are clear. If water does not flow out under the vehicle, use a thin wire to clear any blockages.
Ensure all drains are functioning properly before proceeding.

3. Replace Damaged Door Seals

Tools Required: Flathead screwdriver, replacement door seals
Remove the old door seals by prying them gently with a flathead screwdriver.
Clean the area where the new seal will be applied to ensure a good bond.
Install the new door seals by pressing them firmly into place, ensuring they make a tight seal.

4. Repair Windshield Seal

Tools Required: Sealant (automotive-grade silicone), caulking gun
Inspect the windshield for gaps in the sealant. If found, apply a bead of sealant around the edges of the windshield.
Smooth the sealant with your finger to ensure a tight seal and allow it to cure as per the manufacturer's instructions.

5. Check Cabin Air Filter Housing

Tools Required: Screwdriver set
Remove the cabin air filter cover and inspect for any water intrusion. If water is present, ensure that the drainage area is clear of debris.
Replace any damaged components if necessary.
