Are the Drain Holes of a New Car Usually Open or Blocked?

[AdalineFitz]

New car drain holes are not blocked. Here is some extended information about drain holes: 1. Location: The sunroof drain holes of a car are usually located inside the A-pillar and C-pillar 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 towards the drain holes and then exits the vehicle through the drain pipes. 2. Hazards: If the sunroof drain pipe is blocked, water may flow into the car, causing water ingress in the cabin. Once the drain holes are clogged, leaks and water seepage can occur inside the car, damaging the interior panels in minor cases or leading to mechanical components and engine circuit system damage in severe cases. Therefore, it is essential to keep the sunroof drain pipes clear and perform regular maintenance on the sunroof.
