What fuse controls the temp gauge and fuel gauge

Hello, Unfortunately, the entire instrument cluster is powered by the same input, so if the gauge is the issue, it is likely that the cluster will need to be shipped out for repair by a third party. You may, however, have an issue with data input from the fuel sender, coolant temperature sensor, or engine control module (depending how the system is constructed). It would be more surprising that the two independent sending units failed at one time, but it could happen.
