oedometer stopped working on 2005 chevy Silverado what is the cause?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If your Silverado's odometer just stopped working with no warning or erratic behavior, it's likely an issue with the instrument cluster or a faulty vehicle speed sensor (VSS). The VSS sends data to the odometer, and if it's not working, the odometer won't either. Alternatively, it could be an electrical issue within the instrument cluster itself. Since you're looking to get it repaired locally and quickly, I recommend taking it to a certified repair shop (repairpal.com) to diagnose whether the issue lies with the VSS or the instrument cluster.
