Gauge cluster not working

Hello, sounds like some kind of instrument cluster communication issue. Check the wiring harness to the cluster. Use a diagnostic tool capable of performing testing with Infiniti body module items such as the instrument cluster to see if there are any trouble codes set and monitor data sent to the cluster. Also, it's important to ensure you have needed battery reference voltage at all times. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
