To find the correct fuse:
1. Consult your owner's manual: This is the best place to start. It will have a diagram showing the location of both fuse boxes and a legend identifying which fuses control what circuits. Look for the fuses related to the taillights, rear lights, or park lamps.
2. Check both fuse boxes: Carefully inspect all fuses in both the under-hood and interior fuse boxes. Look for blown fuses (look for a broken filament inside the glass or a visibly melted fuse).
3. If you can't find the fuse in either box, there could be other reasons for the tail lights not working. A bad bulb, wiring issue, or even a problem with the Body Control Module (BCM) are possibilities. In this case, taking your car to a mechanic is the best course of action.
Without your owner's manual, providing a specific location is impossible and could lead to incorrect information. Always refer to your owner's manual for the most accurate and safest information.
