Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked in a dry, well-ventilated area.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Cabin Air Filter

Open the glove compartment and remove any contents.
Locate the cabin air filter access panel, typically found behind the glove compartment.
Remove the access panel by unscrewing or unclipping it.
Pull out the old cabin air filter and inspect it for dirt or moisture.
Replace with a new cabin air filter, ensuring it is oriented correctly.
Reattach the access panel and secure the glove compartment.

3. Repair or Replace Weather Seals

Inspect door and window seals for cracks or wear.
If damaged, remove the old seals carefully using a trim removal tool.
Clean the surface where the new seal will be applied.
Apply new weather stripping, ensuring a tight fit against the glass.
Press firmly to ensure proper adhesion.

4. HVAC System Inspection

Start the vehicle and turn on the HVAC system to the defrost setting.
Check for proper airflow and temperature from the defrost vents.
If airflow is weak, inspect the blower motor and associated fuses.
Clean any debris from the HVAC intake area to enhance airflow.

5. Address Moisture Issues

Inspect the interior for damp spots or signs of leaks.
Dry any wet areas with towels, and use a dehumidifier if necessary.
Consider using moisture absorbers in the cabin to reduce humidity levels.
