It really depends upon the type of car (year, brand, model, etc.). I had the same issue on a 90 Honda Accord. This particular car had a sending unit on the transaxle (transmission) that failed. The connection from the sending unit to the speedometer is electrical. I replaced the sending unit and all was well. Other cars have a cable that connects from the transmission to the speedometer. If you have this type of car, the problem could be the cable, the gear at the end of the cable that runs off of the transmission or the speedometer itself. More information is needed to provide further details. What type of car do you have? Do you have a manual?
you can go to speedometer and out of speedometer
If the speedometer breaks, it effects the odometer. Check the speedometer cable it may be broken, even under the insulation.
The gauge has failed.
If the odometer stopped working and the speedometer and cruise control still work, you have a bad odometer. It is part of the speedometer assembly so the whole thing will have to be replaced.
check the fuse, the speedometer does not run off of a fuse
The speedometer and odometer are electrically operated. There is no mechanical connection to the drivetrain. If there is no power, they don't work.
The speedometer and odometer may stop working in a Nissan Pathfinder due to an electrical short. It may also need a new spark plug.
If both the speedometer and odometer stopped working it is probably the speed sensor in the transmission gone bad. If only the speedometer quit you may have to replace the dash cluster with a reconditioned unit.
the speedometer on my 97 toyota camary stopped working and the check engine light came on why
If the odometer has failed, does the speedometer still work? They are both driven by a cable which spins. If the speedometer is still working, than the odometer has jammed. Probably a dealer fix.
If your odometer/speedometer stopped working, then you must replace the "vehicle speed sensor" located on top of the differential if your have a manual transmission.
The odometer on a 96 Ford Explorer is tied into the speedometer. If the speedometer is working then there is a gear problem inside of the speedometer causing the odometer to not work.
