To find the relevant fuse(s), you need to consult your owner's manual. It will have a fuse diagram showing the location of the fuse box(es) (there's usually one under the hood and one inside the vehicle, often under the dashboard) and which fuses control what circuits. Look for fuses related to "instrument panel," "backlighting," "illumination," or similar terms.
Without your owner's manual, providing a specific location is impossible and attempting to guess could lead to further electrical issues.
