Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 112.
Headlamp Wiring
The headlamp wiring is protected by four internal
fuses in the underhood fuse block. An electrical
overload will cause the lamps to go on and off, or
in some cases to remain off. If this happens,
have your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal fuse in the underhood fuse block. 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, be
sure to get it xed.
The rear washer pump is controlled by a relay
located in the engine compartment, behind
the windshield washer uid reservoir. The rear
wiper motor is protected by a fuse located in the
instrument panel fuse block.
Power Windows and Other Power
Options
Circuit breakers in the instrument panel fuse panel
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 xed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers, and fusible thermal links.
Look at the silver-colored band inside the fuse. If
the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new one of
the identical size and rating.
If you ever have a problem on the road and do not
have a spare fuse, you can borrow one that has
the same amperage or use one of the spare fuses
in the underhood fuse block. Just pick some
feature of your vehicle that you can get along
without, like the radio or cigarette lighter, and use
its fuse if it is the right amperage. Replace it
as soon as you can.

There are two fuse blocks in your vehicle, the
instrument panel fuse block and the underhood
fuse block.
Instrument Panel Fuse Block
The instrument panel fuse block is located at the
right end of the instrument panel, on the
passenger’s side of the vehicle. Open the front
passegner’s door, and remove the cover, to
access the fuse block.
Your vehicle may not have all of the fuses listed.

Maintenance Footnotes
#Lubricate the suspension, steering linkage,
transaxle shift linkage, and the underbody contact
points and linkage.
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, cha ng,
etc. Inspect disc brake pads for wear and rotors for
surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check
parking brake adjustment.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts, signs of wear, or lack of lubrication. Inspect
power steering lines and hoses for proper
hook-up, binding, leaks, cracks, cha ng, etc.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings and clamps; replace with
genuine GM parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.(d)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.
(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. If your vehicle
has a built-in child restraint, make sure the harness
straps, latch plates, buckle, clip, child head
restraint, and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken
airbag coverings, and have them repaired
or replaced. The airbag system does not need
regular maintenance.
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring
anchor and release pawl, hood and door hinges,
rear folding seats, liftgate hinges, fuel door
hinge, power sliding door cable, and sliding door
track(s). More frequent lubrication may be required
when exposed to a corrosive environment.
