If blockages are found, carefully remove them to ensure smooth operation of the sunroof.

4. Check and Replace the Motor (if necessary)

If the motor was tested and found to be non-functional, disconnect the motor from its connector.
Remove the motor by unscrewing it from its mounting points.
Install the new motor by securing it in place and reconnecting the electrical connector.

5. Lubricate Sunroof Mechanism

Apply a silicone-based lubricant generously along the sunroof tracks and moving parts.
Manually operate the sunroof to distribute the lubricant evenly.
