Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 78.
Headlamp Wiring
The headlamp circuit is protected by individual
fuses in the underhood fuse block. An electrical
overload will cause the fuse to blow. If this
happens, have the headlamp system checked
right away.
Windshield Wiper Fuses
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, have it xed.
Power Windows and Other Power
Options
Circuit breakers in the 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.
459

Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links in the
wiring itself. This greatly reduces the chance
of res caused by electrical problems.
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. Spare fuses and
a fuse puller are located in the underhood
fuse block. SeeUnderhood Fuse Blocklater in
this section.
Instrument Panel Fuse Block
Some fuses are in a
fuse block located on
the end of the
instrument panel on the
passenger side.
To get to the fuse block lift up on the side panel.
A fuse usage chart is on the inside of this
panel.

(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
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 airbag coverings,
and have them repaired or replaced. The
airbag system does not need regular maintenance.
(f)Lubricate all key lock cylinders. Lubricate all
hinges and latches, including those for the
body doors, hood, secondary latch, pivots, spring
anchor, release pawl, rear compartment, glove
box door, console door, and any folding seat
hardware. 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:
In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C) or
higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
(i)Drain, ush, and rell cooling system. This
service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 360 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and ller neck. Pressure test the cooling
system and pressure cap.
(j)Check throttle 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.

Automatic Transaxle Shift Lock Control
System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the
vehicle moves, you or others could be
injured.
1. Before you start, be sure you have enough
room around the vehicle. It should be parked
on a level surface.
2. Firmly apply the parking brake. SeeParking
Brake on page 115.
Be ready to apply the regular brake
immediately if the vehicle begins to move.
3. With the engine off, turn the ignition to RUN,
but do not start the engine. Without applying
the regular brake, try to move the shift
lever out of PARK (P) with normal effort. If the
shift lever moves out of PARK (P), contact
your GM Goodwrench
®dealer for service.
Ignition Transaxle Lock Check
While parked, and with the parking brake set, try
to turn the ignition to OFF in each shift lever
position.
The ignition should turn to OFF only when the
shift lever is in PARK (P).
The ignition key should come out only in OFF.
Contact your GM Goodwrench
®dealer if service
is required.
