How to Deal with Water Leakage from the Sunroof and Water Intrusion Inside the Car?
3 Answers
Water leakage from the roof is most likely due to aging sunroof sealing strips, which require timely replacement by the owner. If cracks appear on the roof, leading to water leakage, it is recommended to perform panel beating and repainting. It is necessary to clean and unclog the drainage pipes. Point the nozzle of a high-pressure air gun at the inlet of the sunroof's drainage hole and use high-pressure airflow to blow out debris from the outlet of the drainage hole. Regularly clean the sunroof tracks to prevent dust accumulation and check the lubrication condition of the tracks.
Last month, my car's sunroof leaked, and the floor inside got all wet. I immediately pulled over to a safe spot, grabbed a dry towel to soak up the water to prevent it from spreading to the electronics, then used a hairdryer to dry the edges of the carpet to avoid mold. After that, I checked the sunroof and found that the sealing strip had aged and developed small gaps, allowing rainwater to seep in. I went to the hardware store to buy a new sealing strip and replaced it myself—saving money and time. I also make sure to park away from areas with lots of leaves to prevent clogging the drainage holes. After water gets in, it's important to check if the wiring under the floor is damaged, as it could affect the airbags. So, I recommend getting a full inspection at a professional shop this weekend for peace of mind.
When driving in the rain, I encountered a leaking sunroof with water droplets dripping onto the seats, which was quite annoying. The first step is to ensure safety: slow down, pull over, and turn on the hazard lights. Avoid turning on the AC immediately to prevent water from entering the system. If you have a vacuum cleaner handy, it's best to suck up the water stains, or use old clothes as rags to wipe them. Next, locate the source of the leak—usually, it's due to clogged drainage tubes or cracked seals. A simple fix is to use a wire to unclog the drainage holes. For long-term maintenance, regularly clean the sunroof gaps and apply lubricant to the tracks. After water ingress, the interior can develop odors, so placing a dehumidifying charcoal bag helps disperse moisture and prevent bacterial growth. Remember, don’t wait until the problem becomes severe to fix it—small issues turning into big ones will cost you more in the long run.
