What Are the Reasons Why the Car Door Always Fails to Close?
2 Answers
The reasons why the car door fails to close include: displacement of the door hinge or lock clip, malfunction of the door lock, or failure of the door handle. Below are detailed explanations and solutions: Displacement of the door hinge or lock clip: Use a T-20 spline to remove the small cover of the door handle. Open the door, and there is a small hole on the door edge. Use the T-20 spline to loosen the screw inside, allowing the small cover of the door handle to be removed by hand. Then, you will see the cable inside stuck in the slot of the door handle. If the cable is tightly stretched, it will be more difficult to open the door. Therefore, adjusting the cable to be slightly looser will help. Malfunction of the door lock: The locking mechanism of the door has changed, causing the car door to fail to close. When removing the door lock, you need to dismantle the control device of the door lock and remove the fixing clip between the control device and the lock device. After installing a new lock, repeated adjustments are necessary until the door can open and close normally. Failure of the door handle: The reason is that the cable of the door handle has an issue, and the position where the cable is stuck is not appropriate, making it more difficult to open and close the door, or even impossible to close. Simply adjusting the cable to be slightly looser will solve the problem. Additionally, the friction between the door handle and the lock post is significant, and prolonged use leads to poor lubrication of the switch, which in severe cases can cause the entire door to fail to close. Applying some lubricant appropriately at the door lock can resolve this issue.
Once when I was helping my neighbor fix their car, I found the door wouldn't close properly. The most common issues are loose or rusty door hinges, which happen when they're not maintained for a long time. Another problem could be a faulty door lock mechanism, like a stuck or worn-out lock block, causing a clicking sound when closing but not locking. Aging weatherstripping is also a culprit—when the rubber seal deforms or falls off, the door doesn't shut tightly, leading to wind noise. Body deformation, especially in older cars after a collision, can cause misalignment. In winter, ice may block gaps, or dirt can get stuck in the door frame. If these issues aren't fixed, they can lead to water leaks during rain and damage the paint. Try tightening the hinge screws and spraying some lubricant on the lock mechanism. If that doesn't work, take it to a repair shop for a professional inspection.
