How do you repair the speedometer on a 98 Chevy prizm?

To repair the speedometer on a 1998 Chevy Prizm, first check the speed sensor located on the transmission for any faults or disconnections. If the sensor is faulty, replace it, as it sends speed data to the speedometer. Additionally, inspect the wiring and connectors for any damage or corrosion. If the speedometer still doesn't work after these checks, the issue may lie within the instrument cluster itself, which may require further diagnosis or replacement.
