The 2012 Nissan Altima features two primary fuse boxes that are essential for the vehicle's electrical system. Understanding their locations and the function of each fuse can help you troubleshoot electrical issues effectively.

Fuse Box Locations

  • Passenger Compartment Fuse Box: Located under the dashboard on the driver's side, near the steering wheel. To access it, remove the cover by pulling it down. The diagram for the fuses is usually found on the inside of this cover.

  • Engine Compartment Fuse Box: Situated in the engine bay on the right side, near the battery. This box contains fuses and relays for various engine functions. To access it, unclip the cover by pressing on the tabs.
