Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. 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
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, be sure to get it ®xed.
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 Ð like the radio or
cigarette lighter Ð 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.

(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 blade inserts 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. 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 air bag
coverings, and have them repaired or replaced. (The air
bag 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. Applying silicone grease on weatherstrips
with a clean cloth will make them last longer, seal
better and not stick or squeak.
(g)If you drive regularly under dusty conditions, the
®lter may require replacement more often.
(h)Change automatic transaxle ¯uid and ®lter if the
vehicle is mainly driven under one or more of these
conditions:
þIn heavy city traffic where the outside temperature
regularly reaches 90ÉF (32ÉC) or higher.
þIn hilly or mountainous terrain.
þWhen doing frequent trailer towing.
þUses such as found in taxi, police or delivery
service.
(i)Drain, ¯ush and re®ll cooling system. See Engine
Coolant on page 5-22for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and ®ller neck.
Pressure test the cooling system and pressure cap.
(j)
Check system for interference or binding and
for damaged or missing parts. Replace parts as needed.
Replace any components that have high effort or
excessive wear. Do not lubricate accelerator or cruise
control cables.
(k)A ¯uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the ¯uid level checked. Add ¯uid if needed.
