How to Deal with Car Sunroof Leakage?
2 Answers
Turn on the vehicle's ignition and then press the sunroof switch button to open the sunroof. The first step is to observe the car's sunroof. You can find a drainage outlet on the sunroof track, one on each side. The task is to pour water into these drainage outlets, ensuring both sides are filled. Check if water flows out from the front fender liner. If water is seen flowing out from the fender liner near the front wheels, it indicates that the sunroof drainage pipe is clear. This is part of sunroof maintenance. With frequent summer rains, regular cleaning is beneficial for the vehicle. Use a towel to wipe away dust and, ideally, use an air hose to clean the sunroof drainage outlets. For sunroof care, this step is essential: apply a small amount of lubricant to the sunroof tracks and then use a screwdriver to spread it evenly.
After driving for so many years, the most annoying thing is a leaking sunroof. Actually, it's not difficult to handle it yourself. First, fully open the sunroof and carefully check if the drainage channels are blocked by leaves or mud. Use a damp cloth to thoroughly clean the tracks. The drainage holes are usually located at the four corners; use a thin wire or bicycle brake cable to gently unclog them, but don’t push too hard to avoid puncturing the hose. Aging seals are also common—if they feel hard or cracked to the touch, it's time to replace them. You can buy new seals online for around a hundred bucks. When parking, try to avoid spots under trees, and clean the tracks every quarter. Remember to ask the car wash staff to flush the drainage holes. Once, I neglected it for half a year, and the leaked water soaked the headliner, costing me over a thousand to fix—totally not worth it.
