Question about 2005 Dodge Caravan

2005 Dodge caravan dashboard indicator lights and dials went haywire

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?

    The exact thing happened to me today! I have a 2005 Caravan, and without warning, all of my gauges read 0 and my mileage indcator and gear box lights went out. Also, the AC unit stopped blowing cold air. However, the performance of the van was fine during this. After tuening van off for about 10 minutes and then restarting, everything worked again, but the check engine light came on.

    Glad to know I'm not the only 1 with the problem. It seems to get a voltage spike becuase all gauges go up and down, all dash lights flicker, headlights flicker, stereo pops loud before it turns off then back on, and odometer starts flickering. Then it stops for about 5 minutes before it starts all over again. Now recently, it won't start. all lights come on fine, but takes at least 10 times of turning on and off before it finally turns over. It's quite embarrassing when we have passengers and they see our van lighing up like a christmas tree!

    I have similar problems. Oil light comes on but the oil is fine...car runs fine. Headlights will go off while driving (REAL FUN WHEN DRIVING THROUGH MOUNTAINS AT NIGHT WITH NO MOON!)

    I have a 2008 grand caravan with 5,000 miles on it and it does the same thing, very scary!!

    put the key into the ignition and once i switch the car to the on position all the gauges jump up from 0to 120 back down to0. My fuel gauge also goes from half tank to full to empty back to the normal amount in the tank weird

    My 2005 caravans lights flicker when driving. Just the lights, all gauges and all instruments ok. Vehicle runs excellent. Mechanic tested battery ok, tested alternator suggested replacing, did so, problem still there. Does it take the OBC to regulate voltage to the lights??? Could it b headlight switch cause there is no effect on anything else in the van.

    I fixed the problem!!! Tried cleaning the grounds on the main body and the side panel and that did NOT work. Took the instrument cluster out and re-soldered the connections. Then (and here's what I think really fixed it) we looked at the wires that control the driver side sliding door. It was having issues opening and closing, so I figured that might be the problem. Took the wires out of the casing under the door and sure enough, it was crimped and barely hanging together. We soldered the wires back together and covered it with electrical tape. That was back in August and we haven't had the dashboard disco or a door problem since and its now mid-April...9 months .

    Apparently, the main wires that run EVERYTHING run under the door, so when it was crimped, it affected all the electrical components it controls.

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.

    I did what ozonepro2002 said but my connection was not rusted. I did the steps anyway. But, when putting everything back the Negative battery terminal came off in my hand. I reassembled it and it was fixed. Later, the odometer lights start to flicker and then I checked the battery connections again to find that they have worked loose again. Tighten them and no more flickering. It flickers before it really gets going crazy. Make sure the wires strands do not wiggle within the connection (terminal) and that the terminal does not spin or move on the battery post. BOTH the positive and negative cables!

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.

I checked the 2 grounds in the engine and the one on the b pillar and they weren't corroded at all. I cleaned them anyway and the problem went away for about a week...and now its happening again. Any other solutions?

The gas gauge on my 92 Dodge Grand Caravan stopped working over the past two days. Two days ago it seemed to be fine. Yesterday it indicated that I had a quarter tank when it should have been 3/4 like the...


worth checking the fuel tank for holes or there might be some fuel delivery pipes leaking badly. Or it might be an O2 sensor not giving correct signal to ecu thus consuming so much fuel.
