If the odometer is not working while the speedometer functions in a Mazda B2500, the issue may be related to a faulty gear or drive mechanism within the speedometer assembly. Typically, the speedometer uses a cable or electronic signal from the vehicle's speed sensor, which can still operate even if the odometer's internal gears are malfunctioning. Another possibility could be a problem with the vehicle's instrument cluster itself. A thorough inspection of these components is recommended to identify the exact cause.
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.

I replaced one on my 2000 Mazda b2500. it's located on top of the differential. You un hook the one wire harness, remove one bolt and pry it out with a screw driver. It's not in there too tight, comes out pretty easy. It fixed my speedometer, ABS light and check engine light. I had to use a mirror fixed above the differential and a flash light to see what I was working on. Or you can just feel for it. You can get the part from autowarehouse.com for about $18, great place for parts. Now mine is a 2000 yr. I don't know if the 1999 would be the same or not. Good luck. By the way, dose anyone know the difficulty factor on changing the spark plugs on this 2000 Mazda b2500 4 cylinder engine? It doesn't look like fun to me.
