More than likely, it sounds like your odometer cable has been disconnected or is failing. A new odometer cable can be picked up at any auto parts seller.
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.
My odometer stopped working about a month ago.
My CHI hairdryer stopped working. Who can repair them?

The gauge has failed.

you can go to speedometer and out of speedometer

Check the speed sensor.
"The fuses are good." Well, your odometer certainly isn't.
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.
