Solution

1. Preparation

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

2. Replace Cabin Air Filter

Tools Required: Screwdriver, replacement cabin air filter.
Remove the glove box by unscrewing the screws and gently detaching it from the hinges.
Locate the cabin air filter compartment and remove the old filter.
Insert the new cabin air filter according to the airflow direction indicated on the filter housing.

3. Inspect and Repair Seals

Tools Required: Silicone sealant or adhesive, clean cloth.
Conduct a visual inspection of door seals and window seals for any signs of wear or damage.
Clean the surfaces where seals contact the body with a cloth.
Apply silicone sealant to any compromised areas to prevent water intrusion.

4. Clear Sunroof Drainage Tubes

Tools Required: Flexible wire or compressed air.
Locate the sunroof drainage tubes, usually found at the corners of the sunroof.
Use flexible wire to clear any blockages or apply compressed air to ensure free flow.
Test the drainage by pouring a small amount of water into the sunroof channel and checking for proper drainage.

5. Check AC System Functionality

Tools Required: AC gauge set, refrigerant.
Turn on the vehicle and set the AC to the maximum setting.
Use an AC gauge set to check the pressure levels; if low, recharge the system with the appropriate refrigerant.
Ensure the AC is blowing cold air and dehumidifying the cabin effectively.
