Detailed methods for unclogging the two drainage holes at the rear of the car sunroof are as follows: 1. Inflation Method: Use an air pump gun, align it with the drainage holes of the two front drainage pipes inside the sunroof, and use high-pressure airflow to blow through the pipes. Remember to cover with a cloth to prevent strong airflow from splashing dirty water onto your body or inside the car. 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. Enema Method: Use a syringe to flush the drainage pipes, which can effectively clear them. Practical experience has proven this method to be highly effective and simple to perform.
Last month, I discovered the sunroof was leaking and found out the drainage holes were clogged. After struggling for a while, I learned how to clear them. The method is to slowly insert a thin fishing line or an old network cable into the hole and gently push out the blockage. Avoid forcing it to prevent puncturing the hose. Park the car on level ground, open the sunroof, and locate the two small holes at the rear, usually hidden in the interior seams. If completely clogged, use a compressed air can to blow air into the holes, pressing lightly a few times to clear the sludge. The consequences of clogging are severe, as rainwater can backflow into the car and wet the electrical circuits, leading to costly repairs. It's recommended to use this method quarterly for prevention to avoid surprises. Additionally, clean the sunroof tracks to prevent the accumulation of leaves and dirt, which can cause blockages. Overall, maintaining an older car requires careful attention.
