Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and ensure the sunroof is closed.
Disconnect the vehicle battery for safety.

2. Inspect and Clean the Sunroof Seal

Tools Required: Soft cloth, mild detergent.
Wipe down the sunroof seal and the surrounding frame with a soft cloth and mild detergent to remove dirt and debris.
Inspect the seal for cracks, tears, or any deformities. If damaged, proceed to replace the seal.

3. Clear the Drainage Tubes

Tools Required: Compressed air or a flexible wire.
Locate the drainage tubes, which are typically found in each corner of the sunroof frame.
Use compressed air or a flexible wire to gently clear any obstructions in the drainage tubes.
Test the drainage by pouring a small amount of water into the sunroof channels to ensure it flows freely through the tubes.

4. Realign the Sunroof

Tools Required: Torx screwdriver or appropriate socket set.
If misalignment is suspected, remove the sunroof from the frame by unscrewing the mounting bolts.
Carefully adjust the sunroof's position to ensure it sits flush with the roof.
Re-secure the sunroof, ensuring it operates smoothly without gaps.

5. Seal Replacement (if necessary)

Parts Required: New sunroof seal.
If the sunroof seal is damaged, remove the old seal by carefully prying it off the frame.
Clean the area thoroughly to ensure good adhesion.
Install the new seal, pressing it into place firmly to avoid gaps.
