Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the battery to prevent electrical issues while working on components.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter compartment, usually behind the glove box.
Remove the glove box to access the filter.
Take out the old filter and inspect it for dirt or blockages.
Install a new cabin air filter (use OEM or equivalent).

3. Check Seals and Weatherstripping

Visually inspect all door seals and window seals for cracks or wear.
Apply a silicone lubricant to weatherstripping if it appears dry or damaged.
Replace any damaged seals to prevent moisture ingress.

4. Examine Climate Control System

Start the vehicle and turn on the climate control system.
Adjust settings to different modes (defrost, AC, etc.) and listen for unusual noises.
Ensure the AC system is working effectively and is blowing cool air. If not, consider recharging the AC.

5. Inspect for Coolant Leaks

Check for any signs of coolant leaks under the dashboard or around the heater core.
If coolant is suspected, replace any damaged hoses or the heater core as needed.
