Solution

1. Preparation

Gather tools and materials.
Park the vehicle on a level surface and ensure it is turned off.
Disconnect the vehicle battery to avoid any electrical issues during repairs.

2. Inspect and Clean Sunroof Seals

Remove any debris or dirt from around the sunroof seal using a soft cloth and mild cleaner.
Inspect the rubber seals for cracks or deterioration. If damaged, replace the seals.
Ensure the seals are properly seated and aligned.

3. Clear Sunroof Drainage System

Locate the sunroof drainage channels, typically found at the front corners of the sunroof.
Use compressed air or a flexible wire to clear any blockages in the drainage tubes.
Pour a small amount of water into the sunroof channels to confirm that it drains freely from the bottom of the vehicle.

4. Adjust Sunroof Alignment

If the sunroof is misaligned, loosen the mounting screws on the sunroof frame using a socket set.
Carefully adjust the sunroof to ensure it is level and flush with the roofline.
Tighten the screws to the manufacturer’s specified torque (check service manual for exact values).

5. Reassemble and Test

Reconnect the vehicle battery.
Close the sunroof and perform a water test by pouring water over the sunroof area.
Check inside the cabin for leaks and ensure the drainage system is functioning correctly.
