Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid any electrical issues.

Open the sunroof fully.
Locate the drainage channels at the corners.
Use compressed air or a flexible wire to clear any blockages.
Test drainage by pouring water into the channels and confirming it exits underneath the vehicle.

If necessary, remove the windshield trim carefully.
Apply a high-quality automotive sealant around the edges of the windshield.
Reinstall the trim and ensure a proper seal.
