Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Allow the vehicle to cool down if it has been running.

2. Inspect and Replace Seals

Remove the sunroof trim panel using a trim removal tool to expose the seals.
Inspect the rubber seals for any visible damage.
If damaged, remove the old seal by carefully prying it off the sunroof frame.
Clean the area with isopropyl alcohol to remove any adhesive residue.
Install the new seal, ensuring it aligns properly and adheres firmly.

3. Clear Drainage Tubes

Locate the drainage tubes usually found at the corners of the sunroof.
Use compressed air or a flexible wire to clear any blockages from the tubes.
Ensure the tubes are securely connected and not pinched during the sunroof operation.
Test the drainage by pouring a small amount of water into the sunroof tray and observing if it drains properly.

4. Adjust Weather Stripping

Inspect the weather stripping around the sunroof and roofline.
If misaligned, carefully pull it away and reposition it to ensure a tight seal.
If the weather stripping is damaged, replace it using the same procedure as the sunroof seals.

5. Reassemble and Test

Reattach the sunroof trim panel and ensure it is secure.
Reconnect the vehicle battery.
Perform a water test to ensure there are no leaks after repairs.
