What is the reason why the dashboard door light is always on?
2 Answers
When the dashboard door light is always on, it indicates that the door is not properly closed. The door has two locks; if you close it gently, only the first lock is engaged. If you don't close it firmly, the indicator light will remain on. Here is some relevant information about car doors: 1. Design requirements: Ensure ease of entry and exit for passengers, with the maximum opening angle controlled at around 65° to 70°. During the opening process, the door should not interfere with other parts. When closed, the door must be securely locked to prevent it from opening while driving. 2. Definition: The car door provides access for the driver and passengers, isolates external interference, reduces side impacts to some extent, and protects the occupants. The aesthetics of the car are also related to the design of the door.
I've been driving for over 20 years and have seen the dashboard door light staying on many times. The most common reason is that the door isn't closed properly, especially the rear door which tends to get stuck and not latch correctly. Try slamming it shut to see if the light goes off. If it's still on, it's likely an issue with the door lock sensor - that little device on the door frame that detects whether the door is open or closed. When it gets dirty or worn out, it can give false readings. A short circuit in the wiring could also be the culprit, like when wires get frayed and make poor contact. This is a safety concern - a lit door light means the door might actually be open, which could be extremely dangerous if it flies open at high speed. It also drains your battery faster, so don't delay fixing it. I'd suggest first checking the door locks yourself, and if that doesn't work, take it to a repair shop to replace a small component. It won't cost much but will give you peace of mind.
