Remove the sunroof trim panel carefully using a trim removal tool.
Inspect the rubber seals around the sunroof for cracks or deterioration.
If damaged, remove the old seals and clean the surface.
Apply new adhesive and install the new sunroof seals as per the manufacturer's specifications.

4. Adjust Sunroof Alignment
