Solution

1. Preparation

Tools Required:
- Flathead screwdriver
- Soft cloth
- Bucket or container
- Water source (for testing)
Safety Warnings:
- Ensure the vehicle is parked on a level surface.
- Disconnect the battery if working with electrical components.

2. Inspect and Clean the Sunroof Seal

Carefully inspect the rubber seal around the sunroof for cracks or deterioration.
If damaged, replace the seal with a new OEM part.
Clean the seal using a soft cloth and a mild soap solution to remove dirt and debris.

3. Clear the Drainage Tubes

Locate the drainage outlets which are typically found in the corners of the sunroof frame.
Use a long, flexible tool (like a wire or pipe cleaner) to gently clear any obstructions in the drainage tubes.
Pour a small amount of water into the sunroof channels to confirm that water flows freely through the tubes and exits under the vehicle.

4. Test Sunroof Alignment

Open the sunroof fully and check for any misalignment.
If misaligned, adjust the sunroof mechanism according to the manufacturer's specifications. This may involve loosening and repositioning the mounting screws.

5. Final Assembly and Testing

Reassemble any components removed during inspection and cleaning.
Close the sunroof and perform a water test by pouring water over the sunroof to ensure no leaks occur.
Check the interior for any signs of water intrusion.
