Why are all the car dashboard needles not moving?
2 Answers
The following details the reasons why dashboard needles may not move: 1. If the car dashboard needles are not moving, first check if the flexible shaft connection is disconnected, then observe whether the mileage numbers still increase when the car is moving. When the readings of automotive electrical instruments are abnormal, and it is inferred that there may be a grounding fault inside the sensor or in the wire between the sensor and the indicator instrument, the disconnection method is often used for inspection. 2. The fuse responsible for the starter motor is damaged: It is important to note that when the vehicle fails to start, do not continuously attempt to start the engine, as continuous attempts can cause the battery to continuously discharge, leading to a complete loss of power.
If all the needles on my car's dashboard stop moving, I must say this is a fairly common issue. It happened once when I was driving my Toyota Corolla—all the gauges like the speedometer and fuel gauge froze, which really gave me a scare. I quickly pulled over to check the cause and found that a fuse had blown. The fuse for the instrument system is usually in the fuse box; just refer to the manual to locate and replace it. Additionally, a weak or aging battery can also trigger this issue—when the voltage is too low, the dashboard stops working. I tested the battery voltage and found it was偏低. Loose or corroded wiring connections are another potential hazard, such as moisture seepage during the rainy season causing poor contact. When inspecting, don’t overlook the engine's starting performance. If the engine starts normally but the dashboard doesn’t work, the internal module might be damaged and require professional repair. This issue carries significant risks, as misjudging speed can lead to accidents, so I recommend stopping immediately to address it. After a quick check with basic tools, send it for repair. Regular maintenance of the battery and wiring harness can help prevent this issue.
