Repair Instructions

Step 1: Inspect and Replace the Sunroof Seal

Remove the Sunroof Panel:
- Open the sunroof fully and use a Phillips screwdriver to remove the screws holding the sunroof panel in place.
- Gently lift the sunroof panel out of its tracks.
Check the Seal:
- Inspect the rubber seal for any signs of damage or wear. If it is cracked or deteriorated, replace it.
- Clean the area where the seal sits to ensure a good bond with the new seal.
Install New Seal:
- Apply adhesive (if required) and carefully install the new seal, ensuring it sits properly in the groove.

Step 2: Clear and Unclog Drainage Tubes

Locate Drainage Tubes:
- Identify the drain tube locations; they are typically found at the corners of the sunroof frame.
Clear Blockages:
- Use a flexible wire or drain cleaning tool to gently push through the tubes to dislodge any debris.
- You can also use compressed air to blow through the tubes, ensuring they are clear.
Test Drainage:
- Pour a small amount of water into the sunroof channel to verify that it drains properly through the tubes and exits under the vehicle.

Step 3: Reassemble and Test

Reinstall the Sunroof Panel:
- Carefully place the sunroof panel back into its tracks and secure it with screws.
Test for Leaks:
- Conduct a water test by running water over the sunroof area and checking for any signs of leaks inside the vehicle.
Final Inspection:
- Recheck the alignment of the sunroof and ensure it opens and closes smoothly without resistance.

Conclusion

If these steps do not resolve the issue, it may be necessary to consult a professional technician, as other factors such as body damage or incorrect installation during manufacturing may contribute to the leak. Regular maintenance and inspections of the sunroof system can help prevent future leaks.
