Solution

1. Preparation

Gather tools: screwdriver set, vacuum with a brush attachment, disinfectant spray, and a new cabin air filter.
Ensure the vehicle is parked in a well-ventilated area.

2. Remove Cabin Air Filter

Open the glove compartment and remove any contents.
Locate the stops on either side of the glove compartment and compress them to allow the compartment to drop down.
Remove the cabin air filter cover (usually secured with clips or screws).
Pull out the old cabin air filter, noting its orientation.

3. Clean HVAC System

Use a vacuum with a brush attachment to clean the area where the cabin air filter was installed.
Spray a disinfectant solution into the HVAC housing to kill mold and mildew. Ensure that the solution is designed for automotive use.
Allow the disinfectant to sit for the recommended time as per the product instructions.

4. Install New Cabin Air Filter

Insert the new cabin air filter in the same orientation as the old one.
Reattach the cabin air filter cover securely.
Reinstall the glove compartment by reversing the removal process.

5. Check Drain Tube

Locate the air conditioning drain tube under the vehicle.
Inspect for blockages and clear any debris using a flexible wire or compressed air.

6. Verify System Functionality

Start the engine and turn on the air conditioning to the highest setting.
Monitor the airflow for any lingering odors and confirm that the system is operating effectively.
