Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle in a dry area and ensure the sunroof is closed.
Disconnect the vehicle battery to prevent any electrical issues (if necessary).

2. Inspect and Replace Seals

Tools Required: Flathead screwdriver, adhesive sealant (OEM recommended), cleaning cloth.
Remove the sunroof glass panel by loosening the screws or clips (refer to the service manual for specific instructions).
Clean the area where the seals sit using a cleaning cloth to remove debris and old adhesive.
Apply the new sealant or replace the sunroof seals as needed.
Reinstall the sunroof glass panel, ensuring it fits snugly against the new seals.

3. Clear Drainage Tubes

Tools Required: Compressed air or a thin flexible wire.
Locate the sunroof drainage tubes, typically found in the corners of the sunroof frame.
Use compressed air or a flexible wire to clear any blockages from the drainage tubes.
Ensure that the drainage tubes are securely connected at both the sunroof and the exit points.

4. Adjust Sunroof Alignment

Tools Required: Torque wrench, small socket set.
With the sunroof closed, visually inspect the alignment of the glass panel.
If misalignment is detected, adjust the screws or bolts that hold the sunroof assembly in place.
Tighten all screws/bolts to the manufacturer's specified torque values to ensure proper alignment.
