Solution

1. Preparation

Tools Required: Screwdriver set, trim removal tools, flashlight.
Ensure the vehicle is parked on a level surface.
Disconnect the battery if working near electrical components.

2. Inspect and Replace Sunroof Seals

Sub-steps:
1. Use trim removal tools to carefully detach the headliner panel surrounding the sunroof.
2. Remove any screws securing the sunroof assembly if necessary.
3. Carefully lift the sunroof glass to access the seals underneath.
4. Inspect the rubber seals for cracks or detachment; replace if worn.
5. Apply weather stripping adhesive if seals are loose rather than replacing.

3. Clear Drainage Tubes

Sub-steps:
1. Locate the drainage tubes, usually found at the corners of the sunroof frame.
2. Use compressed air or a flexible wire to clear any blockages in the tubes.
3. Pour a small amount of water into the sunroof channels to ensure proper drainage.

4. Align Sunroof Assembly

Sub-steps:
1. Check the alignment of the sunroof frame by comparing it to the vehicle’s body panels.
2. Loosen the mounting screws if misalignment is found and adjust the frame.
3. Tighten the screws to the manufacturer’s specified torque (typically around 7-10 Nm).

5. Reassemble and Test

Sub-steps:
1. Reattach the sunroof glass and secure it according to manufacturer specifications.
2. Reinstall the headliner panel and ensure all clips and screws are in place.
3. Test the sunroof operation to ensure it opens and closes smoothly.
4. Conduct a water test by spraying water on the sunroof and checking for leaks inside the cabin.
