Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid any electrical issues during the process.

Use a wet/dry vacuum to remove any water from the carpets and footwells.
Use a moisture absorber (like silica gel packs) to dry out the interior.

Identify the drainage tubes from the sunroof and windshield.
Use compressed air or a flexible wire to clear any blockages.
Ensure that water drains freely from these areas.

5. Clean HVAC System

Access the HVAC system (may require removing the dashboard).
Use a mold cleaner or mixture of vinegar and water to clean the evaporator core.
Ensure proper airflow through the system and allow it to dry completely.
