Solution

1. Preparation

Gather tools and parts: OBD-II scanner, Phillips screwdriver, trim removal tool, shop towels, new cabin air filter, silicone sealant (if needed).
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to avoid any electrical issues while working.

2. Replace Cabin Air Filter

Locate the cabin air filter compartment, usually behind the glove box.
Open the glove box and remove any items inside.
Use the trim removal tool to detach the glove box from its hinges.
Remove the cover of the cabin air filter compartment by unscrewing any screws or unclipping it.
Take out the old cabin air filter and inspect for dirt or blockages.
Install the new cabin air filter, ensuring it is oriented correctly (check airflow direction).
Reassemble the cover and glove box.

3. Inspect and Repair Door and Window Seals

Visually inspect all door seals for cracks, tears, or distortion.
If any damage is found, clean the area with a mild soapy solution.
Apply silicone sealant to gaps or damaged areas to ensure a watertight seal.
Check window seals for tightness and reapply adhesive if necessary.

4. Check and Test HVAC System

Start the vehicle and turn on the HVAC system.
Set the system to A/C mode and observe for proper cooling.
Ensure the A/C compressor engages; if not, check A/C fuses and connections.
Use the OBD-II scanner to check for any HVAC-related codes and address them as necessary.
