Fuses
BLOWN
5. Look for a blown wire inside the
fuse. If it is blown, replace it with
one of the spare fuses of the same
rating or lower.

If you cannot drive the vehicle
without fixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
from one of the other circuits. Make
sure you can do without that circuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown fuse with a
spare fuse that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
fuse with one of the correct rating as
soon as you can.
Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement f use with the proper rating
f or the circuit, install one with a lower
rating.
6. If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem in your vehicle.
Leave the blown fuse in that
circuit and have your vehicle
checked by a qualified mechanic.
