What causes water accumulation in the Song Pro car door?
2 Answers
The reason for water accumulation in the Song Pro car door is the absence of sealing strips around the door or improper installation of the sealing strips. Opening the drainage valve of the car door: There are usually drainage valves at the bottom edge of the car door, with three drainage valves per door. Therefore, water accumulation in the door can be drained by opening these valves. Under normal circumstances, when the car door is closed, the drainage valves are squeezed and automatically open, serving the primary function of automatic drainage. Precautions for drainage: If the car door is deformed or there is a large amount of dust, asphalt, or mud around the valves, it can lead to blockage of the drainage valves, thereby affecting the drainage rate. In such cases, pressing the drainage valve manually will widen the gap, allowing water to be drained by gently lifting the valve. Repeat this process for all three doors. Once the water is drained, the valves will lift and automatically retract.
I've been driving the Song Pro for three years and have encountered door water accumulation several times, usually after rain or car washing, where water fails to drain from the bottom of the door. The most likely reason is that the drainage holes at the bottom of the door are clogged. When dust or leaves block the holes, water can't drain completely and accumulates inside. Once, I opened the door and checked carefully—the holes are positioned quite low in the design, making them prone to collecting debris. Another reason could be aging or deformed door seals, allowing water to seep through gaps and fail to flow into the drainage channel. When the water accumulation was severe, I even heard sloshing sounds inside, which eventually led to poor contact in the door's electronic module. I recommend checking the drainage holes after every car wash and using a thin stick to clear any blockages. If that doesn't work, clean it yourself or take it to a shop to prevent rust. Since I started making it a habit to check regularly, the issue has improved significantly.
