How to Clean a Clogged Car Sunroof Drain?
2 Answers
Use an air pump gun and aim it at the drainage holes of the two front drainage pipes inside the sunroof. 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 onto yourself or the car interior. Flushing the drainage pipe with a syringe should help unclog it. Practical experience has proven this method to be very effective and simple to perform.
I've driven quite a few cars, and clogged sunroof drains are a common issue, usually caused by accumulated mud or leaves. Cleaning is simple: First, locate the drain outlets, typically found in the rubber grommets at the four corners of the roof. Use a soft-bristled toothbrush or a specialized small brush to gently remove debris, then blow through with compressed air. If you don't have tools, you can carefully clear them with a household straw or thin wire. After finishing, pour some water to test if the drainage is smooth. Pay attention regularly, and avoid parking under trees to prevent debris buildup. Regular inspection and maintenance can prevent water leakage issues; otherwise, water seeping into the car can wet the interior or even damage electronic devices. This is how I keep my sunroof clean and avoid the hassle of major repairs.
