Disconnect the vehicle battery to prevent electrical shorts while working.
Ensure the vehicle is parked on a level surface.

Tools Required:

Screwdriver set
Pliers
Clean cloths
Water for testing

2. Inspect and Clean the Sunroof Seal

Use the screwdriver to carefully remove any trim or covers around the sunroof.
Visually inspect the rubber seal for cracks, tears, or debris.
Clean the seal and the channel it sits in using a cloth and mild detergent to remove dirt and debris.

3. Clear Drainage Tubes

Locate the drainage tubes that run from the sunroof to the vehicle’s undercarriage.
Use a small amount of water to test each drainage tube for blockages.
If a blockage is found, use a flexible wire or compressed air to clear the tube.

4. Replace Damaged Seal

If the sunroof seal is damaged, carefully remove it using pliers.
Cut a new seal to the appropriate length if needed, or purchase a pre-cut replacement.
Install the new seal by pressing it firmly into the channel, ensuring it is seated properly.

Reattach any trim or covers removed during the process.
Reconnect the vehicle battery.
Test the sunroof operation and check for proper sealing by running water over it.
