How to Fix a Leaking Sunroof on an Old Lavida?
2 Answers
Solutions for a leaking sunroof on an old Lavida are as follows: 1. First, check if the drainage outlet is clogged with dust, as most sunroof leaks are caused by blocked drainage. 2. When washing the car, use a high-pressure air jet device to blow air towards the drainage pipe and inspect it. 3. Check if there is an issue with the drainage system. There is a recess near the sunroof, and if drainage is poor, water will flow into the interior. The main causes of leakage are the two drainage pipes in the A-pillar, such as aging or damage to the rubber seals, which can lead to leaks.
My old Lavida has been running for almost ten years, and I'm all too familiar with the sunroof leaking issue. The main culprit is the aging drainage pipe joints—if they crack or come loose, water flows directly into the car. Feel the sealing strips on both sides of the sunroof rails; if they’ve hardened or cracked, don’t hesitate to replace them immediately. Another hidden trouble spot is the drainage holes, located at the four corners of the sunroof. If they get clogged with leaves or debris, it’s like a blocked toilet—water can’t drain and ends up overflowing into the car. Last time, my headliner was soaked before I realized the drainage hole under the windshield was blocked. Water pooling here can backflow into the sunroof. For a DIY fix, use a bicycle brake cable to unclog the drainage pipe—it works better than a wire and won’t puncture the hose.
