290 Vehicle Care 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.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
possible. To identify and check fuses, circuit
breakers, and relays, see Engine
Compartment Fuse Block 0 290 ,
Instrument Panel Fuse Block 0 293 ,
and Rear Compartment Fuse
Block 0 295 .
Engine Compartment
Fuse Block The underhood fuse block is on the

component on the vehicle may

component.
