Why is the Civic cruise control dashboard not lighting up?
2 Answers
The reasons why the Civic cruise control dashboard is not lighting up include damaged power supply circuit, blown fuse, battery issues, and damaged dashboard CPU. Damaged power supply circuit: If the power supply circuit for the dashboard is damaged, resulting in an open circuit or short circuit, it can also cause the car dashboard to not light up. Blown fuse: If the power supply fuse for the car dashboard is blown, it will naturally result in no power supply, and the dashboard will not light up. Battery issues: For example, the battery may have reached the end of its lifespan, the battery terminals may be loose with poor contact, or the terminals may be oxidized. Damaged dashboard CPU: If all the indicator lights on the dashboard are not lighting up and the car shuts off immediately after starting, it is likely a problem with the dashboard, with the most common cause being a damaged dashboard CPU.
Last week, I encountered an issue with the cruise control light not illuminating while driving my old Civic on the highway. I tried pressing the steering wheel button harder, but it didn't work. Later, I found out that the steering wheel clock spring was broken, preventing the signal from being transmitted. Actually, the cruise control function involves multiple components: poor contact in the steering wheel buttons, burnt-out dashboard bulbs, or worn-out brake switches under the car could all be potential causes. If the cruise control still works when the button is pressed, it might just be a burnt-out dashboard light. I've taken apart the dashboard before to replace the bulb, but you need to be extra careful not to scratch the panel when doing it yourself, or it might not be worth the effort. I recommend first checking the sensitivity of the steering wheel buttons and then inspecting for any loose wiring connections.
