Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked in a dry area and the engine is off.
Disconnect the battery if working on the electrical system.

2. Replace Cabin Air Filter

Tools Required: Flathead screwdriver, replacement cabin air filter.
Open the glove compartment and remove any contents.
Locate the stops on either side of the glove compartment and push them inward to allow the compartment to drop down.
Remove the cover for the cabin air filter by releasing the clips.
Take out the old filter and insert the new one, ensuring the airflow direction is correct.
Reassemble the cover and glove compartment.

3. Inspect and Repair Seals

Tools Required: Rubbing alcohol, clean cloth, silicone sealant (if needed).
Inspect all door and window seals for any cracks or deterioration.
Clean any dirty areas around the seals using rubbing alcohol and a clean cloth.
Apply silicone sealant to any damaged areas to restore the integrity of the seal.

4. Check Heater Core

Tools Required: Coolant, basic hand tools.
Inspect the passenger side footwell for any signs of coolant leaks.
If wetness is found, replace the heater core by draining the coolant, removing necessary dash components, and installing a new heater core.

5. Verify Air Conditioning Functionality

Tools Required: AC gauge set (optional).
Start the engine and turn on the air conditioning.
Check for proper cooling and airflow from the vents. If the AC is not functioning properly, service or recharge the system as required.
