If the instrument cluster is just mechanical then you will need to pull it out and check that the gears and rod that connect to the odometer are working and still connected and if they are then you will need to have the cluster overhauled by a certified speedometer shop........
You can not for it is illegal to tamper with this and it is tamper proof. If you are trying to show less miles, unscrew the speed odometer cable from the transmission and drive.
If the speedometer works but the odometer does not, the odometer has failed.
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.
There may be a broken gear inside the odometer.
They both work off of the same signal. If the speedometer works but the odometer doesn't, the odometer has failed.
A 1992 Ford Ranger typically has a 5-digit odometer. Most vehicles from that era used mechanical odometers, which usually maxed out at 99,999 miles. If the odometer rolls over, it will reset to zero after reaching that limit.
Look at the odometer, it will tell you what mileage it has.
It depends on whether or not the car has a digital readout. If it has a digital display, chances are it would be a wiring problem, somewhere right behind the odometer. If it has an analog display, since the spedometer still works, chances are the odometer itself (the display) has gone bad--like a little gear in there or something. This is one of the simplest odometer problems to fix; just replace the display piece. If the spedometer wasn't working it would be a whole different story--probably a faulty cable.
not directly... The tach gets its signal from the crankshaft sensor. the signal is processed by the computer where it determains spark timing, fuel ratio and other things. information is relayed via wires to the back of your insterment pannel, and are converted into readable units on your tach. Same with the odometer, it gets its signal from the computer via speed sensor. being you lost both functions on your pannel, i would suspect a faulty cluster.
Have you checked fuse? Try new cable (wire) or connectors. Hope this helps.

As far as I know, you have to replace the cluster.
