How can I fix dash lights that are not working?

Checking the Dimmer Switch

  • Turn your car and headlights on. You don't need to start your car, but you do need power running to the lights. Insert the key in the ignition and turn it to the "on" or "accessory" setting. Then, using your headlamps, turn on your headlights.
  • Locate the dimmer switch for your lights. The majority of automobiles have a dashboard light control switch that dims as well as switches off the dashboard lights. Look for a control device, dial, or knob that is generally located on the console near the steering column or may be part of the headlight switch.
  • Check to see if the problem was caused by a faulty knob, dial, or switch. The dash lights might have been inadvertently switched off if the switch was knocked accidentally. Flip the switch or turn the knob up and check to see whether your dash lights come on or become brighter.

Replacing the Dash Lightbulbs

  • The first step is to remove the battery from the car. To prevent electrical shocks or shorts, always disconnect the battery when working on the electrical components in your vehicle. If you haven't already, turn off your car and remove the key from the ignition. Then, using a wrench, pull out the negative terminal before pulling out the positive terminal.
  • Remove the dashboard trim. The procedure for removing the trim differs depending on the vehicle. Consult your manufacturer's handbook or look for a diagram for your specific make and model online to learn more. Typically, you may start by pulling each piece of trim away from the dash one at a time using a screwdriver.
  • Remove the instrument cluster faceplate. The gauge panel on your car's dashboard is covered by the faceplate. Remove the screws and pry up the faceplate with a nylon pry tool or butter knife wrapped in electrical tape after removing the plate from your vehicle. Disconnect switches, controls, and cables from behind the faceplate using release tabs then pull it out of your dash.
  • Replace the lightbulbs with ones that are identical to the old ones. Visit your local auto part store and pick up some replacement bulbs, ensuring that they match the electrical rating and size of the old bulbs. Avoid handling the new bulbs with your hands because oil might harm them. Put on gloves or cover your fingers with a cloth while twisting in the new lights.
  • Remove the battery from the flashlight and clean it thoroughly. Replace the faceplate and trim, reconnecting the battery in reverse of how it was disconnected. After that, connect the positive terminal to the negative terminal before connecting them together.


If your dash lights have stopped working, it is most likely due to a blown fuse or a problem with the dimmer switch. However, it is also possible that the problem could be caused by loose or damaged wiring, a faulty light switch, or a problem with the instrument cluster itself. In any case, you will need to diagnose the issue in order to find the most appropriate solution.
