The dash lights(speedometer, fuel gauge, and rpm etc) on my 2001 hyundai accent dont light up. ive checked all fuses, ive checked the dimmer switch, ive removed the dash assembly and checked continuity. To save headache i might just run a separate wire from the battery if i cant solve it.

SOURCE: gauge lights not working.

Solved the problem -on of the fuses in the relay box under the hood was bad - Although it is not marked well - It says park and horn????

SOURCE: Fuel gauge not working properly Hyundai Accent

The fuel gauge utilizes a voltage stabilizer located on the back of the instrument cluster. if it's faulty it could cause this problem. The other causes are a wire fault (short) between the gauge and the tank sending unit and the sending unit itself being corroded and stuck in the full position (the float assembly that is). One way to quickly isolate (and maybe eliminate) the problem is to get a used cluster from a wrecking yard and swap it out. If it works normally, there you go... if not you will need to access the tank sending unit (this usually, but not always, involves draining and dropping the tank to get to it. Some cars have an access panel in the body over the fuel tank for this purpose... look under the carpeting in the rear of the vehicle) Once you have access disconnect the power wire (usually red or with a red stripe), and with the key on, the gauge should drop to empty. If it doesn't, the problem is not the sending unit. Hope this helps...;-)

SOURCE: started out with headlights out then the speedometer, odometer, gas gauge, oil, battery, rpm's are not working, fixed the headlight was a fuse but other stuff still won't work.

sounds like your missing a ground somewhere.

If your transmission fluid level is okay, then you need a new speedometer cable. Its not terribly difficult to replace, but it does require you to pull the instrument cluster. A local Hyundai dealership might be willing to photocopy the specific speedometer cable replacement instructions out of the 2004 Accent shop manual.

Hi ahcobras. Did you check that the dimmer switch hasn't accidentaly been turned to the off position? You don't say what car it is on, but as it has cruise control, it probably has a dimmer switch! Instrument lights don't usually have a seperate fuse......
