What Causes the Inner Door Handle to Fail in Opening the Door?
2 Answers
If the inner door handle fails to open the door, it may be due to a damaged lock mechanism or a broken linkage cable. It is recommended to have it inspected and repaired at a service shop. The inner door handle is typically mounted on the door trim panel, while the outer handle is fixed on the door outer panel, facilitating the opening and closing of the door. Both handles are equipped with mechanisms to release the door lock, allowing the door to open when the lock is disengaged. A malfunctioning inner handle can lead to unnecessary inconveniences. Below is an introduction to car doors: 1. Car Door: A car door provides access for the driver and passengers and serves to isolate external disturbances, offering some protection against side impacts and safeguarding occupants. The aesthetic appeal of a car is also influenced by the design of its doors. 2. Door Quality: The quality of a car door is primarily reflected in its crash protection, sealing performance, and ease of opening and closing, among other functional indicators. Crash protection is particularly crucial because side collisions occur with minimal buffer distance, posing a high risk of injury to occupants. A high-quality door typically contains at least two crash beams, which are relatively heavy. Therefore, while better doors tend to be heavier, it is not accurate to assume that the heavier the door, the better its quality.
Last time my car's interior door handle suddenly wouldn't open the door, it really panicked me! The reason might be that the connecting rod of the handle came off or got bent. Sometimes parts inside the door lock can get stuck or rust, causing this too. I was pulling like crazy in the parking lot with no luck, but fortunately a roadside mechanic helped out. When he removed the door trim panel, sure enough the linkage rod had loosened and shifted - just needed to be snapped back in place. This kind of issue is more common in older cars where dust and moisture corrode components. Safety first - if the door won't open during an emergency it could be dangerous, so don't force it to avoid further damage. Now I make it a habit to inspect door mechanisms regularly and apply lubricant every six months to prevent sticking. Small problems can become big ones if neglected.
