3. Turn the knobs counterclockwise and
lower the fuse block.
4. Locate the position of the suspected
fuse by using the chart inside the fuse
block cover.
5. Pull the fuse straight out with the fuse
puller provided on the inside of the
engine compartment fuse block cover.
6. Inspect it and replace if it's blown.
NormalBlown
7. Push in a new fuse of the same
amperage rating, and make sure it fits
tightly. If it doesn't, have an Authorized
Mazda Dealer install it.
If you have no spare fuses, borrow one
of the same rating from a circuit not
essential to vehicle operation, such as
the MIRROR or CIGAR circuit.
WARNING
Always replace a fuse with one of the
same rating. Otherwise you may
damage the electric system.
Replacing the fuses under the hood
If the headlights or other electrical
components don't work and the fuses in
the cabin are OK, inspect the fuse block
under the hood. If a fuse is blown, it must
be replaced. Follow these steps:
1. Turn off the ignition switch and all
other switches.
