Dimmer Switch: If your fuse looks fine, another possible cause of your dash lights not working could be a faulty dimmer switch. This is a switch that is usually located on the dashboard of your vehicle, and it controls the brightness of the dash lights. If the dimmer switch is not working properly, it may prevent your dash lights from coming on at all.
Wiring: If neither the fuse nor the dimmer switch is the cause of your dash lights not working, then there may be a wiring issue. This could be caused by a damaged or loose wire in your vehicle's electrical system. To diagnose this issue, you may need to take your vehicle to a qualified auto repair shop for further inspection.
Light Switch: The dashboard light switch can go bad and not allow power to the dash lights. It also could have come loose and not make good contact. Sometimes just moving it back and forth while on may work to get the lights to start working again.
