Saturn gauge clusters were difficult to repair and replace due to the limited parts. While they did share similarities with GM and Chevy vehicles at the time, the majority of information was linked between the cluster and BCM module.
If you installed a used cluster into your Saturn then the odometer would stop working.
We can repair older Saturn instrument clusters, but there really aren’t that many left on the road so we don’t get that many requests for repair. The newer models, such as the Vue and Outlook were more similar to GM, nearly identical, so repairs and replacements are more easily done.
