How Often Should the Sunroof Drain Holes Be Cleaned?

[VanHenry]

Sunroof drain holes should be cleaned regularly as specified. Below are detailed instructions regarding sunroof drain holes: 1. Introduction: Sunroof leakage is a very common phenomenon. There is one drain hole at each of the four corners of the sunroof, which can be easily seen when the sunroof is opened. Each of the four small holes is connected to a hose, leading to the front and rear of the vehicle. 2. Solutions for Blockage Issues: Air Pump Method. Use an air pump gun to direct high-pressure airflow into the drain holes of the two front drainage pipes inside the sunroof to clear the pipes. Remember to use a rag to block any splashes to avoid dirty water spraying onto yourself or the car interior. Be cautious not to use excessive air pressure, as it may cause the rubber joints and drainage pipes to detach, leading to continued leakage. "Enema Method." Using a syringe to flush the drainage pipes should help clear them. First, use the syringe to extract water from the sunroof drainage channel to prevent water from flowing into the vehicle through the sunroof drainage channel.
