Speedometer cable broken, disconnected.... change your VSS (vehicle speed sensor)
Before you even go that route check your fuses. I have had a 96 Taurus since 97. There's a fuse that controls the speedometer as well as the Power Steering and sometimes the radio. I found this out after installing an after market radio lol.
Those fuse charts are darned confusing! Try 12 and 24 as candidates to start with...

It could be a problem with the speedometer assy, since the two are actually one unit. It could also be a speed sensor which is located in the transmission housing on the the right side output drive axle housing.
The gears in the speedometer are stripped. If the odometer is working then you have input.
TCM Malfunction, And/Or Speedometer Sensor Malfunction.
you can go to speedometer and out of speedometer
Had the same problem off and on in my 1999 Taurus. The speedometer needs to be replaced. The problem is in the speedometer and not the transmission like I was initially led to believe. My mechanic said it wasn't that big of a repair.Coincidentally, the vehicle speed sensor feeds information to both the speedometer and the transmission....See "Related Questions" below for more
Most likely a loose connection or bad sensor it is electronic
If the speedometer and the odometer are not working, I would suspect the VSS (vehicle speed sensor). If only the speedometer is not working I would suspect the instrument cluster has problems.
If the speedometer is not working but the odometer is, I would suspect the dash cluster is at fault. If both speedometer and odometer are not working I would suspect the speed sensor on the transmission is at fault.
why would a speedometer stop working on a Mazda
you maybe needing to replace your speed sensor. mine is doing the same thing and that is what is wrong with it
got the same exact problem.
If the speedometer continues to work - probably a broken gear etc. in speedometer head and probably will have to be replaced. If speedometer does not work -- probably a broken speedometer cable
Bad wheel speed sensor or cluster needs replaced
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.
there is probably a sensor on the transmission that is either gone bad or become loose.
Not knowing the year, make and model vehicle it limits how much we can help you. If the speedometer cluster is digital and both the speedometer and odometer is not working I would suspect the vehicle speed sensor is at fault. If only the speedometer is not working I would suspect the dash cluster is at fault.
The speed sensor needs replaced. It is on the trans.
If it works then all of a sudden it starts bouncing back and forth its your Vehicle speed sensor. NAPA part number Echlin VSS318 for a 98 Taurus. It's a little tough to access but achievable.
Most likely the VSS. Vehicle Speed Sensor. It is mounted on the side of the transmission.
Test all the fuses in the fuse box that's on the driver side of the dash , it could just be a blown fuse.
ignition switch under dash will cause preimpted failure if kicked out sequence with key starting rod.
If the speedometer and odometer are both not working, I would blame the speed sensor. If only the speedometer does not work and the odometer does work, the cluster is bad.
I would follow the cable back to the tansmision. Make sure it is intact and connected at both ends.
possibly a bad/broken speed sensor located on the transmission
fuse to the dash gone ???
