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.
