What would cause an odometer and trip meter to stop working but the speedometer to still work?

If the odometer and trip meter stop working while the speedometer continues to function, it may indicate a problem with the odometer gears or the connection between the odometer and the vehicle's speed sensor. The speedometer typically relies on a different mechanism, such as a cable or electronic signal, which can remain operational even if the odometer is malfunctioning. Additionally, a blown fuse or issues with the vehicle's electronic control unit could also lead to this discrepancy. It's advisable to have the vehicle inspected by a mechanic to diagnose and resolve the issue.
