Tiny dashboard lights don’t typically have their own fuses since they are fed from other sources such as the ECU on modern cars. I would attempt to check the bulb and see if it has failed. You need a full wiring diagram for your vehicle if you want to solve this. A good dealership tech is probably going to give you better advice than you can likely find here. Reading the codes from the ECU might tell you what is wrong easily.
