Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the sunroof is closed.
Disconnect the vehicle battery to avoid any electrical issues during repair.

2. Inspect and Replace Seals

Tools Required: Flathead screwdriver, trim removal tool, adhesive sealant (if needed)
Remove any trim pieces around the sunroof carefully using a trim removal tool.
Inspect the rubber seals for cracks or deterioration; replace if necessary.
If using adhesive sealant, apply it to the new seal and press firmly into place.
Reinstall any trim pieces removed during this process.

3. Clear Drainage Tubes

Tools Required: Compressed air or a flexible cleaning tool
Locate the drainage tubes - usually at the corners of the sunroof frame.
Pour water into the sunroof channels to check for flow.
If water does not exit from the tubes, use compressed air or a flexible cleaning tool to clear the blockages.
Ensure that water flows freely from the drainage points under the vehicle.

4. Check Sunroof Alignment

Tools Required: Socket set
Open the sunroof fully to check for alignment.
If misaligned, adjust the sunroof mechanism using the appropriate socket to realign it properly.
Test the sunroof operation to ensure it opens and closes smoothly without obstruction.
