Subaru BRZ (2017-2020)

Checking and Replacing Fuses in Subaru BRZ

The fuses are designed to melt during an overload to prevent damage to the wiring harness and electrical equipment. The fuses are located in two fuse boxes.

Caution!

Never use a fuse of a higher amperage rating than indicated, or use any other object in place of a fuse.

Location of Fuse Boxes

Engine Compartment Fuse Block:
The underhood fuse block is located on the left side of the engine compartment. Lift the fuse block cover to access the fuses. Push the tabs in and lift the lid off.
