Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a well-ventilated area.
Disconnect the battery to prevent electrical issues while working.

2. Replace Cabin Air Filter

Tools Required: Screwdriver, replacement cabin air filter.
Remove the glove box by unscrewing the screws and gently detaching it.

3. Inspect and Seal Water Leaks

Tools Required: Silicone sealant, cleaning cloth.
Visually inspect all door seals, window seals, and sunroof seals for damage or wear.
Clean the surfaces where the seals contact the body of the vehicle.
Apply silicone sealant to any gaps or damaged areas to prevent water intrusion.

4. Clear Drainage Tubes

Tools Required: Compressed air or a flexible cleaning tool.
