Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery if working on electrical components.

2. Replace Cabin Air Filter

Locate the cabin air filter access panel (usually behind the glove box).
Remove the screws or clips securing the panel and carefully detach it.
Extract the old cabin air filter and inspect it for dirt and blockages.
Insert a new cabin air filter, ensuring it is oriented correctly.
Reattach the access panel and secure it with screws or clips.

3. Inspect and Repair Water Intrusion

Check door seals for any signs of wear or damage; replace them if necessary.
Inspect the sunroof drains by pouring water into the sunroof channel and ensuring it drains properly.
Seal any gaps or openings found during the inspection with appropriate weatherstripping or sealant.

4. HVAC System Maintenance

If the air conditioning is not functioning properly, recharge the refrigerant or repair leaks in the HVAC system.
Clean or replace the blower motor if it is not operating efficiently.
Check the operation of the defrost mode and ensure it directs airflow correctly.

5. Humidity Control

Consider using a dehumidifier bag inside the vehicle to control moisture levels.
Encourage the use of the air conditioning system regularly to help remove humidity from the cabin air.
