Question about 2005 Dodge Caravan
Yesterday my 2005 Dodge Caravan a 3.2L-V6 with about 10,000 miles on it, had all the dashboard indicator lights turn on while driving and at the same time the speedometer, fuel and temperature guages moved wildly as well. Fourtunetly handling, braking and acceleration were not affected during the event which lasted a minute or two then all indicator lights and guages returned back to normal with no further problems for now. Any ideas what happened and could it happen again?
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.

Ozone pro 2002 is correct on the ground underneath the battery.That is the battery to body ground. I will go one further. The instrument cluster ground is located besides the driver seat by the b pillar. Remove the b pillar trim molding and the ground wire is screwed into the body ground. Remove the ground wire and sand paper the paint off and reattached the screw. Ensure the screw is tight and if it doesn't drill a new hole and attach the ground. The battery ground and instrument cluster ground is connected through the body metal. A friend of mine had the same problem and the dealer replaced the body control module, instrument cluster, cleaned the ground below the battery and that did not fix it. I looked over the wiring schematics and found the instrument cluster ground at the b pillar and the ground screw not really tight and it would not tightened. This fixed the problem after my friend spent over a thousand dollars at the dealership.

I am not a mechanic...but my 2000 Dodge caravan has been educating me. My speedometer, fuel and temp dropped to 0 while I was moving. There were several intermittant occasions of guage malfunctions while the car was performing just fine. Turned out to be an electrical problem created by the electrical harness being positioned below the battery and some wiring was eaten through. Rather than spend the time isolating the bad wires, the dealer recommended replacing the entire harness (of course). An expensive fix which we made.

I had a similar problem (e.g., speedometer jumping to 120 and back to zero, etc...) only when starting the van. It turned out to be a battery that needed to be replaced.

The caravans also has a problem with the ground on the dash cluster the ground pin on the printed circuit board where the harness plugs into the dash cluster has a weak solder connection and over time will fail. My warning lights and fuel tach and speedo would come and go. Sometime would come back if I smacked the cluster or would come back when the heater heated the van up. After disassembling the cluster I found a bad solder connection between the pin and circuit board. I resoldered the connection and it has been over 5 years with no problem. 1 hour time and a little solder is much better than a several hundred dollar charge for a new cluster assembly!!

Try pressing in the tripometer turn the key to on to run Mic test. It will reset the gauges so they will work.
