Solution

1. Preparation

Gather necessary tools: vacuum cleaner, clean cloths, automotive cleaner, and possibly a replacement cabin air filter.
Ensure the vehicle is parked in a dry, well-ventilated area.

2. Replace Cabin Air Filter

Remove glove box: Open the glove compartment, remove any contents, and release the stops to allow it to drop down.
Locate and remove the old filter: Find the cabin air filter housing, release the clips, and pull out the old filter.
Install the new filter: Insert the new cabin air filter in the correct orientation (check for airflow direction arrows) and secure it back in place.
Reassemble glove box: Return the glove box to its original position and secure it.

3. Inspect and Seal Door and Window Seals

Visual inspection: Check the rubber seals around doors and windows for cracks or deterioration.
Clean seals: Use a mixture of water and mild soap to clean the seals, and ensure they are free of debris.
Apply seal conditioner: If necessary, apply a rubber seal conditioner to restore flexibility and improve sealing.

4. Clear Drainage System

Locate drains: Identify the sunroof and windshield drains.
Clear blockages: Use compressed air or a flexible cleaning tool to remove any obstructions. Ensure water flows freely through the drains.

5. HVAC System Check

Inspect operation: Start the vehicle and turn on the HVAC system. Check that the defroster works effectively.
Use air conditioning: Regularly run the air conditioning to help dehumidify the cabin air, even in winter.
