Solution

1. Preparation

Tools Required: Screwdriver set, flashlight, water hose or spray bottle, vacuum, towels
Ensure the vehicle is parked on a level surface and the interior is dry for effective inspection.

2. Inspect and Clear Sunroof Drain Tubes

Locate the sunroof drain tubes (typically at the corners of the sunroof).
Use a flexible wire or compressed air to clear any blockages.
Ensure the tubes drain properly by pouring water into the sunroof channel and checking for drainage underneath the vehicle.

Inspect all door seals for cracks or deformation.
If damaged, remove the old seal by pulling it off the door frame.
Clean the area with a mild solvent to remove debris.
Install a new door seal by pressing it firmly into place, ensuring it fits snugly.

4. Examine Windshield Sealing

Inspect the windshield for any visible cracks or gaps.
If found, consult a professional for windshield resealing or replacement.
Ensure that the windshield trim is intact and secure.

5. Clear HVAC Drain Hose

Locate the HVAC drain hose, typically found underneath the vehicle near the passenger side.
Use a small flexible tool or compressed air to clear any blockages.
Check for proper drainage by pouring a small amount of water into the HVAC system area.

6. Inspect A-Pillar and Other Areas

Remove the A-pillar trim for inspection.
Check for any signs of water intrusion or damaged seals.
Address any issues found by resealing or replacing affected components.
