Checking and Replacing Fuses in Subaru Legacy
The fuses are designed to melt during an overload to prevent damage to the wiring harness and electrical equipment.
Caution!
Never replace a fuse with one having a higher rating or with material other than a fuse because serious damage or a fire could result.
Location of Fuse Boxes
Instrument Panel Fuse Block:
It is located under the instrument panel behind the fuse box cover on the driver’s seat side. To remove the cover, pull it out.
Engine Compartment Fuse Block:
We recommend that you install only genuine SUBARU accessories on your vehicle.
