I Fuses and Circuit
Breakers
'he wiring circuits in your vehicle are
rotected from short circuits by
a
ombination of fuses, circuit breakers,
nd fusible thermal links in the wiring
self. This greatly reduces the chance of
ires caused by electrical problems.
'here are two fuse centers on your ehicle. One is in the left side of your
lstrument panel.
The other is in the engine compartment.
3pen the cover on either of the boxes to
:xpose the fuses.
>oak at the silver-colored band inside the
'use. If the band is broken or melted,
.eplace the fuse. Be sure you replace a
)ad fuse with a new
one of the correct
rize.
f you ever have a problem on the road
md don't have a spare fuse, you can
)orrow one. Just pick some feature
of
Jour vehicle that you can get along
without
- like the radio or cigarette
ighter
- and use its fuse, if it is the size
IOU need. Replace it as soon as you can.
Headlights
The headlight wiring is protected by a
circuit breaker. An electrical overload
will cause the lights to go
on and off, or in
some cases to remain
off. If this happens,
have your headlight wiring checked right
away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and a fuse. If
the
motor overheats due to heavy snow, etc.,
the wiper will stop until the motor
cools. If the overload is caused by some
electrical problem and not snow, etc.,
be sure to get it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power
windows and other power accessories.
When the current load is too heavy,
the circuit breaker opens and closes,
protecting the circuit until the problem
is fixed or goes away.

5 Cooling: System Service* -
Drain, flush and refill the system
with new or approved recycled
coolant conforming to GM
Specification 1825M. Keep
coolant at the proper mixture as specified. See “Coolant”

maintains proper engine operating temperature.
Inspect hoses and replace if they
are cracked, swollen or deterior-
ated. Tighten screw-type hose
clamps. Clean the outside of the
radiator and air conditioning
condenser. Wash the pressure cap and neck.
To help ensure proper operation,
we recommend a pressure test of
both the cooling system and the
pressure cap.
