Why does my odometer and trip odometer does not work when my speedometer works on my 1992 dodge dynasty can someone help?

If your speedometer is functioning but both the odometer and trip odometer are not, the issue may likely be related to the speed sensor or the internal gears of the odometer. In many vehicles, including your 1992 Dodge Dynasty, the speedometer is driven by a cable or electronic signal, while the odometer relies on a mechanical connection or electronic signal from the same source. A worn-out gear in the odometer mechanism or a fault in the instrument cluster could also be the culprit. It's advisable to check the vehicle's manual for specific troubleshooting steps or consult a mechanic for a thorough diagnosis.
