Gauges not working

[Cooksey]

I've got a 1998 4.0 4x4. None of my gauges are working. (Fuel, temp, tach, speedo, etc) Nothing changed, just stopped working today. I've gone through fuses, and haven't found any blown. Any ideas?

hmm im no expert by any means but on my 84 Bronco II when my gauges acted up it was my ignition. not sure if that would be it but perhaps could be. dont worry in time more wiser people will be able to help you im sure.

If the lights work, it is probably not a grounding problem. It will be absence of 12v in order to affect all gauges. Using a test light, you can trace the wiring. If your truck has a GEM module, and I think it does, it may be the culprit as it controls everything to and from the dash.shady
