* Blown fuse: If the fuse for the dashboard lights has blown, it will need to be replaced. The fuse box is located under the hood, near the battery.
* Bad dimmer switch: The dimmer switch is located on the dashboard, usually to the left of the steering wheel. If the dimmer switch is faulty, it can cause the dashboard lights to go out.
* Faulty wiring: If the wiring that connects the dashboard lights to the power source is damaged or loose, it can cause the lights to go out.
To troubleshoot the problem, you can start by checking the fuse. If the fuse is blown, replace it. If the fuse is not blown, you can check the dimmer switch. If the dimmer switch is not working properly, replace it. If the dimmer switch is working properly, you will need to check the wiring.
If you are not comfortable troubleshooting electrical problems, you can take your car to a mechanic to have it diagnosed and repaired.
