It could be a broken or disconnected speedo cable, that's one thing, the other is that the speedo itself has died that's what happened to me. The thing to do is first check the cable. You need to disconnect it from both ends and see that the inside works, the hard part is removing the instrument panel assy. This whole deal takes a bit of time and sure helps if you've got help but it's doable. If the cable's ok then you need to buy a new instrument assy.
if your speedometer and or odometer isn't working correctly under your motor is a wire clip for you speedometer and odometer jus replace the clip
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 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.
