Solution

1. Preparation

Gather tools and parts:
- Tools Required: Screwdriver set, flashlight, vacuum with a narrow attachment, silicone sealant, cleaning cloths
- Parts Required: Sunroof seal (if damaged), drainage tubes (if blocked or damaged)
Ensure the vehicle is parked on a flat surface with the sunroof closed.

2. Inspect and Clean the Sunroof Seals

Use a flashlight to closely inspect the sunroof seals for cracks or wear.
If the seals are dirty, clean them with a soft cloth and a mild cleaner to ensure a proper seal.

3. Clear the Drainage System

Locate the drainage tubes (usually found at the corners of the sunroof).
Use a vacuum with a narrow attachment to clear any debris from the drainage tubes.
Pour a small amount of water into the sunroof channels to ensure it flows freely through the drainage tubes.

4. Replace Damaged Seals or Tubes

If the sunroof seal is damaged, carefully remove the old seal by pulling it away from the frame.
Clean the area where the new seal will be applied.
Apply the new seal, ensuring it is seated properly and evenly around the sunroof frame.
If drainage tubes are damaged, replace them according to the vehicle manual.

5. Test the Sunroof

Open and close the sunroof several times to ensure it operates smoothly.
Pour water over the sunroof to check for leaks; verify that water drains properly through the tubes.
