Solution

1. Preparation

Gather necessary tools and parts.

Ensure the vehicle is parked on a level surface.

2. Inspect and Clear Sunroof Drains

Use a small flexible wire or a blast of compressed air to check each drain tube.

Visually inspect the rubber seals around the doors and windows.
Replace any damaged or worn seals with new parts (ensure proper fit).

4. Check Windshield Seal

Inspect the windshield for any gaps or signs of improper sealing.
If the seal is compromised, carefully remove the old sealant and apply new automotive-grade sealant.

5. Inspect Cabin Air Filter Housing

Remove the cabin air filter cover, usually located behind the glove box.
