What is the reason for the sunroof leaking continuously?
2 Answers
The reason for the sunroof leaking continuously is: the sunroof glass is not properly closed, or there is a malfunction in the sunroof drainage system. If the amount of rainwater leaking in exceeds the capacity of the drainage system or the drainage system is clogged, the rainwater will overflow the drainage channel and enter the car. The functions of a car sunroof are: 1. Effectively circulate air inside the vehicle, increasing the intake of fresh air; 2. Broaden the view, meeting the needs of mobile photography and videography. The maintenance methods for a car sunroof are: 1. Clean the sunroof drainage channel promptly and regularly wipe the sunroof guide rails with a damp sponge; 2. Apply silicone oil to the sunroof sealing strip after washing the car, which can effectively prevent the aging of the rubber strip and extend the service life of the sealing strip.
I also encountered a sunroof leakage issue the other day, which was quite frustrating. The main cause is likely clogged drainage holes—rainwater flows through the sunroof's drainage system, but over time, leaves or dust accumulate there, blocking the water flow and causing it to overflow into the car. Secondly, the sealing rubber strips may have aged, becoming hard and cracked from constant exposure to sun and rain, failing to seal tightly and allowing water to seep in. My car's rubber strips had been damaged for three years without replacement, leaking like a downpour, which soaked the car mats, caused a musty smell, and nearly corroded the body metal. If the sunroof frame of an older car is loose or deformed, or wasn't installed properly, it's even more prone to problems. The solution is simple: regularly clean debris from the sunroof edges and flush the drainage holes with a soft hose; if it leaks, dry the water immediately, but replacing the rubber strips with professional help is the safest bet.
