Solution

1. Preparation

Gather necessary tools and materials.
Park the vehicle in a well-ventilated area.
Disconnect the vehicle’s battery (if necessary) to ensure safety.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter access panel, usually behind the glove compartment.
Remove the glove compartment by detaching any screws or clips.
Take out the old cabin air filter and inspect for dirt or moisture.
Install a new cabin air filter (ensure it matches the OEM specifications).

3. Seal Inspection and Repair

Visually check the door seals and window seals for wear or damage.
Use a silicone sealant or weatherstrip adhesive to repair any compromised seals.
Ensure all seals are securely attached and free of gaps.

4. Drainage Check

If equipped, open the sunroof and locate the drainage channels.
Use a flexible wire or compressed air to clear any blockages in the drainage tubes.
Ensure that water drains away from the vehicle properly.

5. Test Air Conditioning System

Start the vehicle and turn on the air conditioning to the maximum setting.
Allow the system to run for at least 10 minutes, checking if it is effectively dehumidifying the air.
Monitor the interior for any signs of lingering condensation.
