I've not had this problem in a Caravan, but my Camaro had the same exact problem, so I suspect from my background as an industrial electrician that the answers will be very similar.
The Camaro has a circuit board on the back of the gauge cluster that connects all the gauges. Mine was cracked and the ground foil was not making good connection. ALL the gauges would flutter and then go either full max or full min.
If you can see the bad connection, you can try repairing it with some solder; you may have to scrape the coating off the board to get the solder to stick. That worked for me for about a year. Then I ended up removing the gauge cluster again & getting the entire circuit board from my local junkyard.
You might also check the ground from the frame to the engine block, but I suspect that if that ground was bad, you would have runnability problems. Good luck!
Bad electrical connections.
The year, make and model would help but with some vehicles all the dash cluster gauges are protected with one fuse.
It could, along with the gauges themself and dozens of other causes. A scan tool capable of communication with the body computer and cluster is required to diagnose.
If your Chevy trailblazer 2004 gauges are not working, check your fuel pump.
You need gauges to properly charge it.
go to dodge talk.com and look at the problems these dodges are having my self included
That is the part with the gauges.
You probably have a short in your abs system which has blown your fuse try pulling the fuse. This happened in my 2000 sunfire and I pulled the fuse and all the gauges work now.
Type your answer here... air bag sensor light on? I had one in a 96 in the column, went to local wreaker and changed the column. Works now
Lose of power or ground since all the gauges quit working.
Is it all the gauges or some? You make have to take the instrumental cluster apart. Make sure all the hardness for the gauges are all connected.
Well, voltage wise, you have a lot going on when your are cranking over the engine, so some flutter, or shake is normal.
Why dashboard gauges stopped working on a 2000 Jeep Laredo
my 1998 doge ram van, all my gauges are not working
check your fuses first
In the fuse box under dash, left of steering column.
Answer 85 Toyota PU gaugesSince the speedometer is a mechanical connection and the rest electical, about the only thing that is going to affect them all is water. Does the windshield leak. Could be just bad luck the speedometer went at the same time as the gauges, but doubtful.
A common reason for this is a cracked circuit board in the instrument panel. Do any of the warning lights come on at the same time (ABS, for example)? If you smack the dashboard with your hand sometimes you can make the gauges come on again. It'll likely need a new instrument cluster. --Dennis, ASE Master Tech
#4 fuse blew
because it's old, stupid
Check for a blown fuse.
A wire going to the battery broke off, when it was reconnected the gauges and lights on the gauges start working again, however the speedometer and the tachometer did not operate.
Definitely take apart the gauges, check and make sure all cables are intact.
rpm and speedometer gauges not working 1995 Chevy silverado 2wd
I'm not sure either. I have the same problem. I'm sending mine to a gauge repair shop in MN.
