Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure it is turned off.
Disconnect the negative battery terminal.

2. Replace Cabin Air Filter

Locate the cabin air filter housing, usually found behind the glove compartment.
Remove the glove compartment by unscrewing any screws and detaching it gently.
Take out the old cabin air filter and inspect the housing for debris.
Install a new cabin air filter, ensuring it is oriented correctly.
Reattach the glove compartment.

3. Inspect and Seal Door and Window Seals

Visually inspect all door seals and window seals for damage or wear.
Run your fingers along the seals to feel for gaps or cracks.
Apply a silicone-based sealant to any damaged areas or replace seals as necessary.

4. Check HVAC System Functionality

Start the vehicle and turn on the HVAC system.
Set the system to defrost mode and observe airflow from the vents.
If airflow is weak, inspect the blower motor and related components for issues.

5. Inspect and Repair Windshield Seals

Examine the windshield for any visible cracks, chips, or gaps in the seal.
If defects are found, consider applying a sealant or consult a professional for windshield replacement.

6. Inspect Heater Core

Check the passenger side floor for dampness, which may indicate a leaking heater core.
If dampness is present, consider replacing the heater core. This involves draining the coolant, removing the dashboard, and replacing the core.
