What causes the water sound in car doors?
2 Answers
The reason for the water sound in car doors is that the drainage holes at the bottom of the doors are clogged, which affects the drainage rate. Water accumulates, leading to the sound. It is necessary to clean the drainage holes to allow the water to drain out quickly. Car doors provide access for drivers and passengers, isolate external interference, reduce side impacts, and protect the safety of occupants. The opening methods of car doors are divided into: 1. Forward-opening doors; 2. Rearward-opening doors; 3. Sliding doors; 4. Upward-swinging doors; 5. Folding doors. Car doors consist of the door body, door accessories, and interior trim panels. The accessories include: door hinges, door opening limiters, door lock mechanisms and inner/outer handles, door glass, window regulators, and sealing strips.
Last time I also had water sloshing sounds in my car door, a gurgling noise that clearly indicated the issue was likely a clogged drainage hole at the bottom of the door. When it rains or during car washes, water leaks in, and if the hole is blocked, the water gets trapped inside. This is quite common. I tried opening the door and bending down to locate the drainage hole myself, then carefully poked it with a thin wire or flushed it with water until the water drained out. For prevention, after washing the car, don't just wipe the body—clean out debris from the door seams to avoid rusting the door panel or affecting window operation. If left untreated, long-term water accumulation can corrode internal electronic components or speaker wiring, leading to costly repairs later. I recommend doing a simple self-check first, and if issues persist, take it to a shop—don't delay.
