Where Does the Water Go When the Sunroof Drain Pipe is Clogged?
2 Answers
When the sunroof drain pipe is clogged, water may flow into the car, causing water ingress in the cabin. Once the drain hole is blocked, leaks or seepage can occur inside the vehicle, potentially damaging interior panels in minor cases or leading to mechanical component and engine electrical system damage in severe cases. Therefore, it is essential to keep the sunroof drain pipe clear and perform regular maintenance on the sunroof. Precautions for a clogged sunroof drain pipe: 1. Check the drain hole: If you notice water leaking from the sunroof, inspect the drain hole to see if it is blocked. Parking the car under trees can lead to clogging due to fallen leaves, resulting in sunroof leaks. If the leak is caused by a blocked drain hole, clearing it promptly can resolve the issue. 2. Inspect the sealing strip: If the sunroof sealing strip is damaged, water accumulation on the roof may seep through, causing leaks. Replacing the sunroof sealing strip in time can prevent such leaks.
That day, my car's sunroof drain pipe got clogged, and I was really worried. With nowhere to go, the water overflowed from the sunroof channel, first soaking the fabric lining of the roof, which felt soft like a sponge to the touch. The water then seeped into the inside of the A-pillar, flowing through the gaps into the car and wetting the seat belt socket. Over time, the water dripped all the way down under the floor mats, leaving the entire footwell area damp and soggy. What was even scarier was that after parking, the water seeped into the corners of the trunk, where the spare tools got soaked and rusted. I quickly cleared the blockage, and now I use compressed air to blow out the pipes every quarter to avoid bigger problems.
