the brake pedal and mounted onto the
lower left-hand cowl panel. Remove the
fuse panel cover to access the fuses.

rating. See Changing a Fuse (page 163). Protected Component

CHANGING A FUSE
Fuses WARNING: Always replace a fuse
with one that has the specified
amperage rating. Using a fuse with a
higher amperage rating can cause severe
wire damage and could start a fire. If electrical components in the vehicle are
not working, a fuse may have blown. Blown
fuses are identified by a broken wire within
the fuse. Check the appropriate fuses
before replacing any electrical
components.
