Do you have a question about the Mountain Aire 2003 and is the answer not in the manual?

I need help trying to getting my gauge cluster to work they come on but they move back and forth but not in the right position they need to be. we have tried rerunning wires but nothing seems to be working. any help would be greatly appreciated.

A gauge cluster malfunction in a 2003 Newmar Mountain Aire where the gauges turn on but show incorrect readings is often caused by a failure in the instrument cluster stepper motors or communication issues with the vehicle’s data bus system.
Common causes include:
1. Faulty Stepper Motors: The small motors that control the needle positions may wear out or fail, causing incorrect gauge readings.
2. Poor Ground Connection: A loose or corroded ground can disrupt the signals to the gauges, resulting in erratic behavior.
3. Data Bus Communication Issues: If there is a problem with the multiplexed data bus (often used in RVs), the instrument cluster may receive incorrect or incomplete data from sensors.
4. Faulty Instrument Cluster Circuit Board: Cracked solder joints or failed components on the cluster's circuit board can cause incorrect gauge behavior.
5. Sensor Malfunction: If the sensors providing input (e.g., fuel level, temperature, oil pressure) are faulty, the gauges may display wrong values.
6. Wiring Problems: Damaged or loose wiring between the sensors and the cluster can disrupt signal transmission.
Diagnosis typically involves checking for fault codes, testing ground connections, inspecting the circuit board, and verifying sensor outputs.
