To fix the odometer in your 1990 Plymouth Horizon, start by removing the instrument cluster to access the odometer mechanism. Check for any broken gears or connections, as these are common issues. If you find damaged parts, you may need to replace them or consider a replacement odometer unit. Reassemble the cluster carefully and test the odometer to ensure it's functioning properly.
