A car's dashboard lights may be out as a result of the dashboard lights control switch being off, a blown fuse or bulb in the dashboard, faulty wiring or an issue in the car's electrical system.
A car's dashboard lights control switch can dim dashboard lights as well as turn them on or off. The control panel's brightness control must be turned on for the dashboard lights to work.
Dashboard lights may be disabled as a result of a blown fuse. If this is the issue, the dashboard light fuse, located in the fuse box, must be replaced.
If a car's fuse is working correctly, check the dashboard bulb. It is located on the face plate covering the dashboard gauge panel. If the bulb is damaged or discolored, replace it with the same bulb model.
If a car's dashboard lights control switch is on and the fuse and bulb are not blown, contact a professional to check the car's wiring and electrical system.
