Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle in a dry area and ensure the sunroof is in the closed position.
Disconnect the vehicle battery to avoid electrical issues.

2. Inspect and Replace Seals

Tools Required: Trim removal tool, gasket adhesive, cleaning cloth.
Inspect the rubber seals around the sunroof for cracks or deterioration.
If damaged, carefully remove the old seal using a trim removal tool.
Clean the sealing surface to remove any debris or old adhesive.
Apply new gasket adhesive and install the new seal, ensuring it is firmly positioned.

3. Clear Drainage System

Tools Required: Compressed air or a flexible wire.
Locate the sunroof drain tubes at the corners of the sunroof frame.
Use compressed air or a flexible wire to clear any blockages in the drain tubes.
Test each drain by pouring a small amount of water into the sunroof tray and ensuring it flows freely through the tubes.

4. Adjust Sunroof Alignment

Tools Required: Screwdriver set, torque wrench.
Open the sunroof and locate the adjustment screws.
Loosen the screws slightly and adjust the sunroof to ensure it sits flush with the roofline.
Tighten the screws to the manufacturer's specified torque settings.

5. Reassemble and Test

Reconnect the vehicle battery.
Close the sunroof and ensure it operates smoothly.
Conduct a water test by gently pouring water onto the sunroof to check for leaks.
Inspect the interior for any signs of water intrusion.
