Where is the door drain hole located?
2 Answers
The door drain holes are mostly located at the bottom edge of the car door. There are three small black square holes at the bottom, which are the door drain valves. Here is some additional information: 1. Door drain valves: Under normal circumstances, the door drain valves can automatically open and drain water when the door is closed through the squeezing of the valve. If they cannot drain automatically, it may be due to door deformation or the accumulation of dust, asphalt, mud, etc. around the door, which prevents water from draining even when the door is closed. The longer this persists, the more water will accumulate. 2. Hazards of water accumulation in the door: It may cause corrosion and rust; it can damage the wiring; and the speakers and window switches may also be damaged.
I often need to clean the door drain holes when driving. They are located at the very bottom of the door. When you open the door and look closely at the edge, you will find several small holes or gaps. These holes allow rainwater to drain out. If they get clogged, water can accumulate, leading to rust or strange noises. When inspecting, squat down and feel along the bottom edge of the door with your hand to locate them. For cleaning, you can use a thin wire to gently poke through, but avoid using hard objects that might damage the interior. Cleaning them every six months is a good practice to prevent door panel corrosion or issues with window operation. Also, pay attention to parking spots—avoid parking under trees or in dusty areas to reduce the risk of clogging. Developing these small habits can make vehicle maintenance much easier.
