Will the sunroof drainage holes get clogged if not opened?

[OCarlos]

Sunroof drainage holes may get clogged if not opened. Here is some extended information: 1. Location: The sunroof drainage holes in a car are usually located inside the A-pillars and C-pillars of the vehicle. There is a round rubber plug, with one on each side of the rear longitudinal beams, similar to the front. When water enters the sunroof channel, it flows toward the drainage holes and then exits the vehicle through the drainage pipes. 2. Hazards: If the sunroof drainage pipes are clogged, water may flow into the interior, causing water leakage inside the cabin. Once the drainage holes are blocked, issues like water leakage and seepage may occur inside the vehicle, potentially damaging the interior panels in minor cases or leading to mechanical component and engine circuit system damage in severe cases. Therefore, it is essential to keep the sunroof drainage pipes clear and perform regular maintenance on the sunroof.
