Q: Dash lights not working

asked by on

The dash lights are not working.

Hi, have you checked the fuse for the instrument cluster? This is a quick and easy check, however, if the fuse is blown, it blew for a reason, so replacing it is only a temporary solution. As the circuit will surge again at some point blowing the fuse and we are back to square one. If the fuse is intact, there may be an issue with the wiring or the rheostat. The rheostat controls the brightness of the lights and if it’s not working correctly, none of the lights would display on the dash. You could try adjusting this to see if the lights were just too dim. As for the wiring, there is either an issue with the power going to the cluster or the ground may not be working properly. A certified technician would be able to help you inspect these components and further diagnose the issue.
