Normal Blown
5. Insert a new fuse of the same amperage
rating, and make sure it fits tightly. If it
does not fit tightly, have an expert
install it. We recommend an
Authorized Mazda Dealer.
If you have no spare fuses, borrow one
of the same rating from a circuit not
essential to vehicle operation, such as
the AUDIO or CIGAR circuit.
CAUTION
Always replace a fuse with one of the
same rating. Otherwise you may
damage the electric system. 6. Reinstall the cover and make sure that
it is securely installed.
Replacing the fuses under the hood
If the headlights or other electrical
components do not work and the fuses in
the cabin are normal, inspect the fuse
block under the hood. If a fuse is blown, it
must be replaced. Follow these steps:
1. Make sure the ignition is switched off,
and other switches are off.
2. Remove the fuse block cover.
3. If any fuse but the MAIN fuse is blown, replace it with a new one of the
same amperage rating .
