How to Unclog the Drainage Pipe of the Cruze Sunroof?

[GavinLee]

After clogging, you can find a 6mm iron wire (usually clogged by dust and mud), then poke open the four drainage holes, and pour water on top until the water drains out. Use an air gun to aim at the two front drainage holes inside the sunroof, and use high-pressure airflow to blow through the drainage pipe. Remember to block with a rag to prevent the strong airflow from splashing dirty water on you. Using a syringe to flush the drainage pipe should be able to clear it. Practical operation proves that this method is very effective and simple to perform. First, use a syringe to extract the water from the sunroof drainage channel to prevent water from flowing into the car through the sunroof drainage channel.
