4. If the fuse must be replacedimmediately, borrow a
replacement fuse with the
same amperage from the
fuse block. Choose a vehicle
feature that is not needed
to safely operate the
vehicle. Repeat Steps 2–3.
5. Insert the replacement fuse into the empty slot of the
blown fuse.
At the next opportunity, see
your dealer to replace the
blown fuse.
Headlamp Wiring
An electrical overload may
cause the lamps to go on and
off, or in some cases to remain
off. Have the headlamp wiring
checked right away if the
lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats
due to heavy snow or ice, the
windshield wipers will stop
until the motor cools and will
then restart.
Although the circuit is
protected from electrical
overload, overload due to
heavy snow or ice may cause
wiper linkage damage. Always
clear ice and heavy snow from
the windshield before using
the windshield wipers.
If the overload is caused by an
electrical problem and not
snow or ice, be sure to get it
fixed.
Fuses and Circuit
Breakers
The wiring circuits in the
vehicle are protected from
short circuits by a combination
of fuses and circuit breakers.
This greatly reduces the
chance of damage caused by
electrical problems.
{Danger
Fuses and circuit breakers
are marked with
their ampere rating. Do not
exceed the
specified amperage rating
when replacing fuses and
circuit breakers. Use of an
oversized fuse or circuit
breaker can result in a
vehicle fire. You and others
could be seriously injured or
killed.
{Warning
Installation or use of fuses
that do not meet GM’s
original fuse specifications is
dangerous. The fuses could
fail, and result in a fire. You (Continued)
