Hello, welcome. My name isXXXXX will do my very best to assist you with your question. I apologize if you have been waiting long for a response.

From what you are describing this issue is consistent with failed stepper motors in the back of the instrument cluster, these are plastic motors in the back of the cluster that work each gage and they strip out over time. This was a very common issue on these vehicles and to correct the issue the cluster is replaced or rebuilt.
