Quote: "You should check for fault codes first. If there is one it could be a sensor. Also verify if the odometer does not work at the same time. If it does work and the mph needle does not the problem could be in the speedo head/cluster."
When the speedo quits, the odo and trip meter also quit. Have scanner, will check! Now, will scanner show a code if the speedo IS working at the time I plug in the scanner? Or only when the speedo is dead?
If the speedo does not work the computer should induce and store a code.
