Locate the drainage tubes (often found near the sunroof or under the vehicle).
Use a flexible wire or compressed air to remove any blockages.
Ensure that water flows freely through the tubes.

4. Inspect and Repair Windshield Seal

Visually inspect the windshield seal for cracks or gaps.
If damaged, apply a suitable automotive adhesive sealant along the edges of the windshield.
Allow the sealant to cure as per the manufacturer's instructions.
