What to Do When Water Leaks into the Car Due to Clogged Sunroof Drainage Tubes?
1 Answers
When water leaks into the car due to clogged sunroof drainage tubes, you should use an air pump to blow high-pressure air into the drainage holes of the two front drainage tubes inside the sunroof to clear the blockage. After blowing, pour water into the sunroof and check if water flows out from the drainage outlets near the front wheels. If water flows out, the drainage tubes are successfully unclogged. Then, remove the accumulated water inside the car. There are several rubber plugs at the bottom of the vehicle chassis; opening these plugs can drain the accumulated water from the cabin. Below is more information about sunroof drainage tubes: 1. Sunroof Structure and Drainage Principle: The sunroof has two sliding rails on the left and right sides to allow front and back movement. At the front corners of these rails are the drainage holes, connected to a drainage channel between them. Rainwater enters the channel, flows to the drainage holes, and then through drainage tubes that run along the A-pillars of the car, exiting near the front wheel mudguards. Some drainage holes may also be located at the rear sides of the sunroof, with water exiting through the C-pillars. 2. Common Sunroof Leakage Issues: Clogged or broken drainage tubes. This can cause water to seep from the sunroof gaps into the interior. If the tubes are broken, water may also leak through the A-pillars or C-pillars. Another issue is aging sunroof seals, leading to water seepage. 3. Note: It is best not to open the sunroof when driving on bumpy roads. When the sunroof is open, some overlapping components may shift, and driving on uneven roads can not only make passengers uncomfortable but also easily damage the sunroof.
