Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid electrical issues while inspecting components.

2. Replace Cabin Air Filter

Locate the cabin air filter access panel (usually behind the glove compartment).
Remove the glove compartment by unscrewing screws or releasing clips.
Slide out the old cabin air filter and inspect for mold or heavy dirt.
Insert a new cabin air filter (ensure it’s the correct part for your model).

3. Check and Clean Air Conditioning Drain

Locate the A/C drain hose underneath the vehicle.
Use a flexible brush or compressed air to clear any blockages in the drain hose.
Pour a small amount of water down the drain to ensure proper drainage.

4. Inspect for Water Leaks

Remove the floor mats and check for moisture on the carpet.
Inspect door seals and window seals for cracks or wear.
Use a flashlight to check under the dashboard for any signs of dampness or leaks.

5. Clean Interior and Vents

Use a fabric cleaner or an upholstery steam cleaner to treat the interior surfaces.
Consider using an ozone generator inside the car to neutralize odors if necessary.
Run the vehicle's ventilation system on high with windows open for a few minutes.
