To fix the speedometer on a 1991 Oldsmobile 88, first check the speedometer cable for any breaks or disconnections, as a damaged cable is a common issue. If the cable is intact, inspect the speedometer itself for any signs of malfunction or wear. You may also need to check the vehicle's vehicle speed sensor (VSS) if equipped, as a faulty sensor can affect the speedometer's accuracy. If these components are functioning properly, consider consulting a professional mechanic for further diagnosis or replacement of the speedometer unit.

Additionally, ensure that the instrument cluster connections are secure and free from corrosion. If all else fails, consider replacing the speedometer or seeking professional help to diagnose any underlying electrical issues.
