Fluid Leak Check
After the vehicle has been parked for awhile, inspect the surface beneath the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning system
is normal. If you notice fuel leaks or fumes, the causes
should be found and corrected at once.
Bulb Replacement
Before replacing any bulbs, make sure all lights are off and the vehicle is
not running.

Downloaded from www.Manualslib.com manuals search engine 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 in the
wiring itself. This greatly reduces the chance of fires caused by electrical
problems. See “Fuses and Circuit Breakers”
in the Index for more
information.
Headlights
The headlight wiring is protected by a circuit breaker in the light switch. 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 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 fixed or goes
away.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by an in-line
fuse
in the battery feed wire. This fuse is near the junction block. See
“Trailer Wiring Harness”
in the Index.

Downloaded from www.Manualslib.com manuals search engine Bulletins cover various subjects. Some pertain to the proper use and care of
your vehicle. Some describe costly repairs. Others describe inexpensive
repairs which, if done
on time with the latest parts, may avoid future costly
repairs. Some bulletins tell a technician how to repair a new or unexpected
condition. Others describe a quicker way to fix your vehicle. They can help
a technician service your vehicle better.
Most bulletins apply to conditions affecting a small number
of cars or
trucks. Your Chevrolet dealer or a qualified technician may have
to
determine if a specific bulletin applies to your vehicle.
You can subscribe
to all Chevrolet’s bulletins by calling Helm, Inc. at
1-800-7824356. This way you’ll get them as they become available.
Individual PSP’s
If you don’t want to buy all the PSP’s issued by Chevrolet for all car or
truck models in the model year,
you can buy individual PSP’s, such as those
which may pertain to a particular model.
To do this, you will first need to
see our index of PSP’s. It provides a variety of information. Here’s what
you’ll find in the index and how you can get one:
What You’// Find in the Index:
A list of PSP’s published by Chevrolet in a model year (1990 or later).
PSP’s covering all models
of Chevrolet cars or light trucks (less than
10,000 pounds (4 536 kg) GVWR) are listed in the same index.
Ordering information so you can buy the specific PSP’s you may want.
Price information for the PSP’s you may want to buy.
How You Can Get an Index:
Indexes are published periodically. Most of the PSP’s which could
potentially apply
to the most recent Chevrolet models will be listed in the
most recent publication for that model year. This means you may want to
wait until
the end of the model year before ordering an index, if you are
interested in buying PSP’s pertaining
to a current model year car or truck.
Some PSP’s pertaining
to a particular model year vehicle may be published
in later years, and these would be listed in the later year’s index. When you
order an index for a model year that is not over yet, we’ll send
you the most
recently published issue. Check the ordering
form for indexes for earlier
model years.
Cut
out the ordering form, fill it out, and mail it in. We will then see to it
that an index is mailed
to you. There is no charge for indexes for the
1989-1 994 model years.
