How to Clean the Sunroof Drain Pipe of the Envision?

To clean the sunroof drain holes, you can directly use a high-pressure air gun to blow them out, which effectively removes dirt from the sunroof drain holes. Cars equipped with sunroofs have drain holes. If there are no drain holes or if they are blocked, the sunroof may leak during rain. There are several types of car sunroofs: 1. Built-in Sunroof: A built-in sunroof refers to a sunroof where the sliding assembly is located between the interior and the roof. Its advantages include a large opening and a sleek, aesthetically pleasing appearance. Most sedans use built-in sunroofs. 2. Pop-up Sunroof: Pop-up sunroofs are compact and have a simple structure. Installed on the roof, they effectively promote air circulation inside the car, allowing fresh air to enter and providing a healthy and comfortable experience for the owner. Additionally, car sunroofs can broaden the field of vision and are often used for mobile photography and videography needs. 3. Panoramic Sunroof: Panoramic sunroofs offer the advantages of an expansive view and excellent ventilation. However, they also have some drawbacks, such as higher costs, the need to clean accumulated dust to avoid obstructing the view, and a reduction in the overall rigidity of the car body, which lowers the safety coefficient.
I remember the last time I cleaned the drainage pipes of my Envision's sunroof, it was quite a task. The sunroof drainage outlets are located in the corners of the roof and can easily get clogged with leaves and dust, causing water leakage into the car during rain. I used a household air compressor, gently blowing air into the drainage outlets—being careful not to use too much force to avoid damaging the pipes. Then, I checked the drainage flow by pouring some water to test it. Although this job is simple, it helps prevent mold inside the car and damage to electronic components. I recommend doing this cleaning every six months, especially before the rainy season. DIY saves money and is safe—just keep a soft brush or specialized cleaning tool handy to avoid damaging the pipe walls with wire brushes. Stay safe throughout the process, and don’t forget to wear gloves to keep your hands clean.
