2005 Caravan I had the same problem with my van gauges bounceing, headlights not comeing on when the switch was turned on.I took a day and downloaded a wireing diagram from dodge and studyed it.GROUND PROBLEM dodge have several ground conections to the body then there is one MAIN BODY GROUND.This is most likely your problem it is easy for any back yard mechanic to fix.This main body ground is located under your battery box.You will have to remove the battery and then the battery box becarful of the battery sensor that is mounted in the bottom of the box.Also there is a hose that you will have to disconnect but dont try to remove it from the box remove it from above the box.After you get the battery and box out you will see a threaded stud with a black wire conected to it this will be rusted because of no antioxide grease applyed.You will have to remove the nut and wire connector clean both and the stud with wire brush or sandpaper.Put antioxide grease or if nothing else some vaseline to keep it from coroading again.put back together and see if this dosent fix your problem.It has been six weeks for me now.good luck.dont forget that neg battery terminal is the first one to disconect and the last to reconect.

you have a bad sending unit inside your tank.
the resistance of the potentiometer inside is broke on the half tank part.

you have to replace it.

hi, yeh it could possibly be a fuse maybe? sometimes the fuse can protect more than one circuit. i would start there.
