Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.

2. Remove Cabin Air Filter

Locate the cabin air filter compartment (usually behind the glove box).
Open the glove box and disconnect any limiting straps.
Remove the old cabin air filter and inspect for mold or debris.
Replace with a new, clean cabin air filter.

3. Inspect and Seal Door and Window Seals

Visually inspect the door and window seals for cracks or deterioration.
Use a silicone-based sealant to repair any damaged seals.
Close the doors and windows to ensure proper sealing.

4. Clear Sunroof Drains (if equipped)

Locate the sunroof drainage channels (usually at the corners of the sunroof).
Use a compressed air canister to blow out any debris or blockages from the drains.
Test the drains by pouring a small amount of water into the channels to ensure it flows freely.

5. Clean and Dry Interior

Remove any damp carpets or upholstery and allow them to dry outside the vehicle.
Use a wet/dry vacuum to extract moisture from the interior surfaces.
Wipe down the interior with a mixture of water and mild detergent to eliminate mold spores.
