Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and turn off the ignition.
Disconnect the battery to avoid electrical shorts.

2. Inspect Sunroof Drains

Locate the sunroof drain tubes.
Use a small flexible wire or compressed air to clear any blockages.
Test the drains by pouring water into the sunroof area and ensuring it flows out the bottom.

3. Check Door Seals

Visually inspect the door rubber seals for cracks or signs of wear.
Replace any damaged seals with OEM replacement parts.
Ensure the doors close tightly against the seals.

4. Examine Windshield Seal

Inspect the windshield for any visible gaps or damage to the adhesive seal.
If leaks are found, consider resealing the windshield using automotive urethane adhesive.
Professional installation may be recommended for proper sealing.

5. Inspect Heater Core

Check for signs of coolant leaking inside the cabin (sweet smell, wetness).
If the heater core is leaking, replace it by following these steps:
- Drain the coolant from the system.
- Remove the dashboard (if necessary) to access the heater core.
- Disconnect the heater core hoses and remove the old core.
- Install the new heater core and reassemble.

6. Check Cabin Air Filter Compartment

Remove the cabin air filter cover.
Inspect for any water accumulation or debris.
Clear any blockages and replace the cabin air filter if necessary.
