Solution

1. Preparation

Gather tools: flashlight, trim removal tools, water hose, towels for drying.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect Door Seals

Remove the door panel using trim removal tools.
Check the rubber seals around the door for tears or wear.
Replace any damaged seals with OEM parts.

3. Clear Sunroof Drains

Open the sunroof and locate the drain holes at the corners.
Use a flexible wire or compressed air to clear any blockages.
Test drainage by pouring a small amount of water into the sunroof channels.

4. Check Windshield Seal

Inspect the perimeter of the windshield for any gaps or damage.
If gaps are found, apply a bead of automotive sealant or consult a professional for resealing.

5. Inspect Cabin Air Filter Area

Remove the cabin air filter cover under the dashboard.
Check for any signs of water entry or debris blocking the filter compartment.
Replace the cabin air filter if it is wet or dirty.

6. Examine Heater Core

Check for coolant leaks around the heater core (under the dashboard).
If coolant is leaking, replace the heater core and address any associated hoses.
