What to Do If the Car Dashboard Lights Stay On and Won't Turn Off?
2 Answers
After closing the car door, the dashboard lights remaining on is one of the car's features, and they will turn off once the car is locked. The dashboard lights change with the headlights' switch; when the headlights are turned off, the dashboard lights will naturally go out. If there is a malfunction in a certain component inside the car, such as the engine, oil, brake system, or water temperature, the issue needs to be diagnosed and resolved, and the fault code should be cleared using a diagnostic scanner.
I encountered the same issue last time I drove. The dashboard light kept staying on and wouldn't turn off, which really annoyed me. It's probably because the door wasn't closed properly. Some cars are designed this way - if the door isn't fully closed, the dashboard light won't turn off, just like when the anti-theft system isn't deactivated. Or it could be a faulty ignition switch stuck in a position where it's not completely turned off, causing the light to stay on. You can first try checking if all doors are properly closed, especially the trunk and all side doors. If that doesn't work, disconnect the negative battery terminal for a few minutes and then reconnect it - sometimes this can reset the system and solve the problem. If it still persists, it might be a broken interior switch module or poor relay contact. I suggest going to a professional auto repair shop for diagnostic testing immediately. Otherwise, leaving the light on for too long could drain the battery, leaving you unable to start the car the next day - what a hassle. Remember to regularly check these switch components during routine vehicle maintenance to prevent minor issues from turning into major problems.
