Disconnect the battery if working on electrical components.

2. Replace Cabin Air Filter

Tools Required: Flathead screwdriver, replacement cabin air filter.
Remove the glove compartment by unscrewing any securing screws and releasing the stops.
Locate the cabin air filter cover, unclip it, and pull out the old filter.
Insert the new cabin air filter following the airflow direction indicated.

3. Inspect and Repair Seals

Tools Required: Silicone sealant, utility knife.
Examine all door seals and window seals for wear or damage.
If seals are damaged, detach them carefully using a utility knife.
Clean the surface area and apply silicone sealant to create a waterproof barrier.
Allow sufficient time for the sealant to cure before closing doors.

4. Clean Drainage Channels

Tools Required: Small brush, compressed air.
Locate the sunroof drainage channels (if equipped) and remove any visible debris.
Use a small brush to clean the channels thoroughly.
Blow compressed air through the drainage holes to ensure they are clear of blockages.

5. Address Windshield Issues
