2. Inspect the Sunroof Drains

Locate the sunroof drain holes, typically found in the corners of the sunroof frame.
Use a vacuum or compressed air to clear any debris or blockages from the drains.
Ensure the drains are free-flowing by running water through them.

3. Check the Sunroof Seal

Visually inspect the rubber seal around the sunroof for cracks, tears, or deterioration.
If damaged, remove the old seal using a flathead screwdriver and clean the area.
Install a new sunroof seal by carefully pressing it into place, ensuring it sits evenly.

4. Verify Sunroof Alignment

Open the sunroof to inspect its alignment with the roof of the vehicle.
If misaligned, use a Torx screwdriver to adjust the mounting bolts, ensuring the sunroof sits flush with the roof.
Close the sunroof to check for proper sealing against the frame.

5. Test the Repair

Perform a water test by pouring water over the sunroof area.
Observe for any signs of leaks or water intrusion into the interior.
If leaks persist, reassess the drain function and seal installation.
