Solution

1. Preparation

Gather the required tools and materials.
Ensure the vehicle is parked in a dry area.
Disconnect the battery if working on electrical components.

2. Inspect and Clean Seals

Tools Required: Soft cloth, mild soap solution.
Clean the existing rubber seals around the sunroof using a soft cloth and mild soap solution to remove dirt and debris.
Inspect the seals for cracks, tears, or hardening, which could impair their function.

3. Replace Damaged Seals

Tools Required: Utility knife, adhesive (if necessary).
If the seals are damaged, carefully remove them using a utility knife.
Measure and cut new replacement seals to the appropriate length.
If the new seals require adhesive, apply a thin, even layer to the sunroof frame before placing the seal.

4. Clear Drainage Tubes

Tools Required: Compressed air or a flexible cleaning tool.
Locate the sunroof drainage tubes, typically found in the front and rear corners of the sunroof frame.
Use compressed air or a flexible cleaning tool to clear any blockages within the tubes.
Ensure that the tubes are securely connected to the drainage points.

5. Test Sunroof Alignment

Tools Required: None specific.
Manually check the alignment of the sunroof to ensure it closes evenly and seals properly.
Make necessary adjustments by loosening and retightening the mounting brackets if misalignment is detected.
