Checking and Replacing Fuses in Subaru WRX

The main fuses are designed to melt during an overload to prevent damage to the wiring harness and electrical equipment. Check the main fuses if any electrical component fails to operate (except the starter motor) and other fuses are good.

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.
