Nope. The speedometer needs a signal from the vehicle speed sensor to operate. Is the check engine light on? If so, scan for any codes that may indicate a VSS problem. If no codes, possible internal cluster issue with the speedometer head
Common problem
You need to take dash apart, remove the whole instrument cluster and send it away for repair......
Search instrument cluster repair on ebay ,
The first thing to do is reach up (if possible) behind the cluster and make sure the plugs to it are fully inserted, push them in or remove and reinsert if possible to reach them. If that doesn't fix the problem the entire cluster must be removed and then sent out for repair to a shop that repair Chrysler electronics.
There's 9 screws in the plastic piece that surrounds the instrument cluster and the lower knee guard, remove those screws and pull the plastic trim away from the dash, disconnect the switches on the left side as you pull outward. Then there's 4 screws that hold the actual instrument cluster in place, remove those and pull the cluster out, unplug the grey plug in the back of the instrument cluster and your done. You may need to set your parking brake and put your transmission in 1st gear of you have a column shifter model.
Hi. There is a speed sensor mounted on the transmission. Check the wires that lead from the sensor to the instrument cluster in your dash. Make sure the speedometer is connected to the sensor, and the connection is not loose. If the wiring at the sensor, and speedometer are ok, simply replace the speed sensor.
Never heard of a battery inside an instrument cluster. Modern clusters do have various capacitors and other electrical components and can be complex to repair when they fail.
There are numerous cluster repair places across the country that do this type repair work. Google "speedometer repairs." You will have to remove the cluster and ship it to them.
