Solution

1. Preparation

Gather tools: vacuum cleaner, cleaning solutions, microfiber cloths, and a replacement cabin air filter if necessary.
Ensure the vehicle is parked in a well-ventilated area and the engine is off.

2. Remove and Inspect Cabin Air Filter

Open the glove compartment and remove any contents.
Locate the cabin air filter access panel.
Remove the panel and take out the cabin air filter.
Inspect the filter for mold, dirt, and debris; replace if necessary.

3. Clean and Deodorize Interior

Use a vacuum cleaner to remove dirt and debris from the cabin, focusing on carpets and upholstery.
Mix a solution of equal parts water and white vinegar or use an automotive upholstery cleaner.
Using a microfiber cloth, clean all surfaces, especially areas where moisture might accumulate, such as under seats and on carpets.

4. Inspect and Clear Drainage Systems

If the vehicle has a sunroof, check the drainage tubes for blockages and clear them with a flexible wire.
Inspect door drains and clear any obstructions to allow proper drainage.

5. Replace Weather Stripping (if necessary)

Examine the weather stripping around doors and windows for wear or damage.
If any seals are compromised, remove old weather stripping and replace it with new, ensuring a tight fit to prevent moisture entry.
