Attention: Before replacing the gear, it is necessary to clean the track related impurities and handle the related lubrication matters, otherwise it may cause blockage and damage to the gear operation.

When the sunroof is closed or opened, if you hear a clicking sound or a squeaking motor running sound, it is usually caused by damage to the internal plastic gears. Replace the metal gears with new ones to solve the problem
