Solution

1. Preparation

Tools Required:
- Screwdriver set
- Flashlight
- Towel or sponge
Disconnect the battery if working on electrical components.

2. Inspect Cabin Air Filter

Open the glove compartment and remove it to access the cabin air filter.
Remove the cabin air filter and check for moisture. If wet, replace it with a new filter.
Ensure the filter housing is dry before reinstalling.

3. Check Seals

Inspect all door and window seals for cracks or deterioration.
Use a silicone sealant to repair any compromised areas.
Ensure windows are closing properly and seals are intact.

4. Drainage System Inspection

Check for clogged drainage holes under the vehicle and around the sunroof (if equipped).
Clear any obstructions using a flexible wire or compressed air.
Ensure that water drains freely without pooling.

5. Examine Windshield and Rear Window Seals

Inspect the edges of the windshield and rear window for any gaps or signs of leaks.
If leaks are found, apply a high-quality windshield sealant to prevent moisture entry.

6. Heater Core Inspection

Look for signs of coolant on the floor mats or inside the vehicle.
If a leak is suspected, replace the heater core following the manufacturer’s instructions. This typically involves:
- Draining the coolant.
- Removing the dashboard for access.
- Disconnecting the heater core hoses.
- Installing a new heater core and reassembling.
