How to Unclog the Two Drain Holes at the Back of a Car Sunroof?

[Hazel]

Here are the methods to unclog the two drain holes at the back of a car sunroof: 1. The Inflation Method: Use an air pump gun, aim it at the drain holes of the two drainage pipes in front of the sunroof, and use high-pressure airflow to blow through the pipes. Remember to cover with a rag to prevent dirty water from splashing onto your body or the car interior due to the strong airflow. The air pressure should not be too strong, as it may cause the rubber joints and drainage pipes to detach, leading to continued leakage. 2. The Enema Method: Use a syringe to flush the drainage pipes, which can help clear them. Practical experience has shown that this method is very effective and simple to perform.
