Hello! Thank you for your feedback. Tesla Model 3 does not have a traditional fuse box like most internal combustion engine vehicles. Instead, Tesla vehicles have a system called a "Power Distribution Unit" (PDU) that manages the flow of electricity throughout the vehicle. The PDU incorporates various circuit breakers and solid-state devices to protect the electrical system from overcurrent conditions. If you encounter any electrical problems in your vehicle, please refer to the owner's manual https://teslamodel3ca.com/info/owners-manuals/ for a detailed answer to any question you may have.
