2012 Buick Enclave speedometer gauge issue
Buick Enclave (2012) Strangest thing recently occurred while on a holiday road trip. The lights on the instruments for the water temperature, fuel level, and battery voltage ceased functioning. The gauge's internal illumination is still functional. Additionally, the tachometer and speedometer's needle and gauge lights both function perfectly. The gauge is difficult to discern on the dark gauge face without the needle's illumination. Need guidance on how to examine the instrument cluster's circuits or replace bulbs.
