What causes the sunroof leakage in the Emgrand GS?

[StLane]

Long-term lack of maintenance leads to aging of the sunroof sealing strip. Common causes of sunroof leakage in cars: Prolonged lack of maintenance causes the sunroof sealing strip to age; driving on bumpy roads with the sunroof fully open can lead to excessive vibration between the sunroof and the sliding rails, causing component deformation; clogged drainage pipes. Maintenance methods: Regularly check the condition of the sunroof rails; reduce the frequency of sunroof use; avoid opening the sunroof when the car is cold in winter; check the drainage status of the sunroof before the rainy season. Replace the sunroof sealing strip; clean small sand particles and dust from the sunroof drainage channel; ensure the sunroof is properly closed; unclog the drainage pipes. The function of a car sunroof is to provide ventilation.
