Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface.
Disconnect the battery (optional, for electrical safety).

Tools Required:

Flathead screwdriver
Torx screwdriver set
Vacuum with nozzle attachment
Water hose
Clean cloths

2. Inspect and Clean the Drainage System

Locate the drainage tubes (usually at the four corners of the sunroof).
Using the vacuum, carefully remove any debris or blockages from the drainage holes.
Pour a small amount of water into each drainage hole to ensure it flows freely.

3. Check and Replace the Sunroof Seal

Remove the sunroof glass (if necessary) by unscrewing the retaining screws using a Torx driver.
Inspect the seal for cracks or deformation. If damaged, remove the old seal.
Clean the area where the new seal will be applied using a suitable solvent.
Install the new sunroof seal, ensuring it fits snugly and evenly.

4. Test the Sunroof Functionality

Reinstall the sunroof glass and secure it with screws.
Operate the sunroof to ensure it opens and closes smoothly without obstruction.
