Solution

1. Preparation

Gather tools: flashlight, flathead screwdriver, hose, towels, vacuum.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Clear Sunroof Drains

Locate the sunroof drainage holes (usually at the corners).
Use a flexible wire or compressed air to clear any debris.
Run water through the drains to ensure proper flow.

3. Examine Door and Window Seals

Visually inspect all door and window seals for cracks or deformation.
If damaged, remove the old seals using a flathead screwdriver.
Replace with new OEM seals, ensuring proper alignment.

4. Check and Clear HVAC Drain Line

Locate the drain line under the vehicle (usually near the firewall).
Use a vacuum to suction any blockage from the drain line.
Test by pouring water into the HVAC system to confirm drainage.

5. Inspect Windshield Seal

Check the perimeter of the windshield for gaps or cracks.
If a gap is found, carefully remove the trim and apply automotive sealant.
Reinstall the trim and allow sealant to cure as per manufacturer instructions.
