How to Deal with Water Accumulation Sound in Car Doors?

[VanAutumn]

You can use the door drain valve to drain the water. The door drain valve will automatically remove the accumulated water inside the door. If the door drain valve is clogged, it will affect the drainage rate. Below are methods regarding a clogged door drain valve: Location of the door drain valve: Generally, it is located at the lowest edge of the door, with three small black squares, which are the car door drain valves. Reason for clogging: The door drain holes are usually located at the lower part of the door panel, with 1-2 holes. Most door panel drain holes do not have a hose for guidance, and rainwater flows directly through the rust-proofed door panel for drainage. Due to their low position, vehicles frequently driven on muddy roads are prone to having these drain holes blocked by mud. Hazards of clogging: Once the door drain holes are clogged, the accumulated water remaining inside the door panel can cause damage to the window regulator, audio system, and central door lock. Cleaning method: The door drain holes can be unclogged using hard objects like iron wires. Special care should be taken when cleaning the drain holes hidden inside the rubber seals to avoid damaging the seals.
