In this article, you will find information about the fuses of the Subaru Legacy / Outback (BL, BP; models 2005, 2006, 2008, and 2009), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.
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. The fuses are located in two fuse boxes. If any lights, accessories or other electrical controls do not operate, inspect the corresponding fuse. If a fuse has blown, replace it.
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. Open the lid that is located above the hood release knob and pull it toward you to remove it.
Engine Compartment Fuse Block:
If a main fuse or fusible link blows after it is replaced, have the electrical system checked by your nearest SUBARU dealer.
