Two fuse panels are positioned beneath the dashboard: the first is on the passenger side, and the second is on the driver side (you may need to remove the protective trim—loosen the fasteners, indicated by arrows, and open the cover). There are also several fuses on the Body Domain Controller, which is located in the passenger-side pillar behind the trim.
