Where are the drainage holes located on the Great Wall C50?

Great Wall C50 has drainage holes for the fuel tank cap, sunroof, under the door panels, trunk, engine compartment, and air conditioning. Below is an introduction to the related drainage holes: Fuel tank cap drainage hole: Open the fuel tank filler cap cover, and you can see a drainage hole at the bottom inside the fuel tank cap. The fuel tank cap is not tightly sealed, and it is concave inside, so a drainage hole is designed. Since the vehicle is used outdoors, wind and sand can accumulate around the fuel tank cap through the gaps of the fuel tank cap. Sunroof drainage hole: Generally speaking, if the sunroof is not opened for a long time, the chance of the four drainage holes at the sunroof being blocked is not high, and blocking one is not enough to cause water to flood into the car. Most water ingress is caused by water seeping through the rubber gaps. Moisture on the interior trim panel is a sign of a blocked sunroof drainage hole, and a detached sunroof drainage pipe can also cause the interior trim panel to become damp. A damp interior not only brings unpleasant mildew odors but also breeds bacteria.
I had just started driving my Great Wall C50 when I encountered a sunroof leakage issue. Later, I learned about the purpose of the drainage holes. These are mainly located in the small holes at the four corners of the sunroof, allowing water to flow out and prevent accumulation. There's also a small gap at the bottom edge of the door that acts as a drainage hole. If not cleaned, they can get clogged with dirt and leaves, causing rainwater to accumulate on the roof or inside the door panels, leading to interior corrosion, metal rust, and even short circuits in the electrical system. I clean them myself once a year by lifting the rubber seal and blowing them out or gently brushing with a small brush. The C50's design is quite user-friendly, with the air conditioning drainage hole located below the firewall at the front of the car. If it gets blocked, condensed water can soak the carpet, which is quite annoying. In short, maintaining these small holes is simple but crucial to avoid expensive repairs later.
