Solution

1. Preparation

Gather tools: water hose, flashlight, towels, vacuum cleaner, and silicone sealant.
Ensure the vehicle is parked on a level surface and in a dry area.

2. Inspect and Repair Weather Seals

Sub-steps:
1. Visually inspect all door and window seals for wear and tear.
2. Replace any damaged weather stripping with OEM parts.
3. Apply silicone sealant to any gaps found in the seals to prevent future leaks.

3. Clear Sunroof Drains

Sub-steps:
1. Locate the sunroof drain holes (usually found at the corners of the sunroof).
2. Use a flexible wire or compressed air to clear any debris blocking the drains.
3. Test drainage by pouring a small amount of water into the sunroof channel and ensuring it flows out of the drain.

4. Check Cabin Air Filter

Sub-steps:
1. Remove the cabin air filter cover (usually located behind the glove box).
2. Inspect the filter for water damage; replace if necessary.
3. Clean the surrounding area to ensure proper airflow.

5. Inspect Windshield Sealing

Sub-steps:
1. Check the windshield for any visible gaps or cracks in the sealant.
2. If leaks are detected, remove the old sealant and apply a new automotive-grade sealant.
3. Allow the sealant to cure as per manufacturer instructions before exposing to water.
