A vehicle speed sensor is the culprit
The speedometer and odometer in a 1990 Chevy Astro Van may not work due to a malfunctioning vehicle speed sensor (VSS), which sends speed data to the dashboard. Additionally, issues such as a broken speedometer cable, faulty instrument cluster, or electrical problems can also cause these gauges to fail. Inspecting these components can help diagnose and resolve the issue.
If both the odometer and the speedometer do not work it may be the speed sensor in the transmission is bad. If only the odometer does not work it is probably a bad cluster.
