What is the method for cleaning the sunroof drainage of the Envision?
2 Answers
To clean the sunroof drainage of the Envision, you can use a high-pressure air gun to blow out the debris, which effectively clears the dirt from the sunroof drainage holes. Cars equipped with sunroofs have drainage holes; if these holes are absent or blocked, the sunroof may leak during rain. The Buick Envision is positioned as a midsize SUV, with a relatively large body size and ample interior space. Its dimensions are 4686mm in length, 1839mm in width, and 1686mm in height, with a wheelbase of 2750mm. The 2020 Buick Envision features a more rugged and bold design, with a new wing-shaped chrome trim running through the LED wing-shaped headlights, widening the horizontal visual effect. The dynamic bumper surfaces and three-dimensional silver lower guard create a full and powerful front end. The rear also adopts a three-dimensional wing-shaped design, with chrome trim connecting the taillights, paired with integrated dual exhaust pipes to enhance the sporty feel.
I recently cleaned the sunroof drains on my Envision, which is quite important. The sunroof drain holes often get clogged due to dust, leaves, and other debris blocking the pipes. If not cleaned, rainwater can leak into the car during rain, damaging the carpet and even electronic components. Cleaning method: First, locate the drain holes, usually near the front corners of the glass—feel around for a small pipe outlet. Then, use a can of compressed air (available at car shops or online) to gently blow air into the pipe to push out the debris. If you don’t have compressed air, you can try using an old bicycle pump connected to a soft hose. Never use a high-pressure water jet or sharp objects to poke the pipe, as this can damage it. After cleaning, pour some water to test if the flow is smooth. I recommend checking every three months, especially if parked under trees, to prevent small issues from turning into costly repairs. Doing it yourself costs almost nothing and saves a lot of time and effort.
