This solution might be a little dated, but if your speedometer cable has broken, that would acuse the speedo to stop working. The fix used to be, to unscrew the speedo cable from the transmision. It is pretty easy to spot, it is an odd looking flexible cable. Then get behind the dash, and unscrew it there, then go by a new speedo cable and replace it. This might not work with some of the newer digital read outs though. What is the make and model of your car?
