Turn Signal and Lane Change indicator
..

." I .. . ..,." .
K2240
The turn signal has two upward (for Right) and two downward \
(for Left) positions. These positions allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down. When the turn is
finished, the lever will return automatically.
A green arrow on the instrument panel will flash in the direction of the turn
or lane change.
To signal a lane change, just raise or lower the lever until the green arrow
starts to flash.
Hold it there until you complete your lane change. The lever
will return by itself when you release it.
As you signal a turn or a lane change, if the arrows flash twice as fast as
normal, a signal bulb may be burned out and other drivers won\
't see your
turn signal.
If a bulb is burned out, replace it to help avoid an accident. If the green
arrows don't go on at all when you signal a turn, check the \
fuse (see
"Fuses" in the Index) and for burned-out bulbs.
Operation of Lights
Although your vehicle's lighting system (headlights, parking lig\
hts, fog lamps,
side marker lights and taillights) meet all applicable federal lighting
requirements, certain states and provinces may apply their own \
lighting
regulations that may require special attention before you operate these lights.
For example, some jurisdictions may require that you operate yo\

mailer. Wiring Harness
K2373
The 7-wire harness is stored under your vehicle along the rear\
frame
crossmember. The harness has a
30 amp in-line fused battery feed wire and
no connector, and should be wired by a qualified electrical se\
rvice person.
Securely attach the harness to the trailer, then tape or strap\
it
to your
vehicle’s frame rail. Be sure you leave it
loose enough so the wiring won’t
bind or break when turning with the trailer, but not
so loose that it drags on
the ground.
Store the harness in its original position. Wrap the harness t\
ogether and tie it neatly
so it won’t be damaged.

vice people.
We hope you’ll want to keep your GM vehicle all GM. Genuine GM parts
have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you’ll want to get the
proper General Motors Service Manual. It tells you much more a\
bout how to
service your vehicle than this manual can.
To order the proper service
manual, see “Service Publications” in the Index.
You should keep
a record with all parts receipts and list the mileage and the
date
of any service work you perform. See “Maintenance Record” in \
the
Index.
CAUTION
I A You can be injured if you try to do service work on a vehicle without
L knowing enough about it.
Be sure you have sufficient knowledge, experience, and the
proper replacement parts and tools before
you attempt any
vehicle maintenance task.
9 Be sure to use the proper nuts, bolts and other fasteners.
“English” and “metric” fasteners can be easily confused.
If you
use the wrong fasteners, parts can later break or fall off. You
could be hurt.

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 wirin\
g
itself. This greatly reduces the chance
of fires caused by electrical problems.
See “Fuses and Circuit Breakers” in the Index for more information.
to use a magnetic screwdriver when installing the screws.
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 for more information.

The fuse block is in
the instrument panel on the driver’s side.
You can remove fuses with a fuse extractor, if you have one. To remove
fuses
if you don’t have one, hold the end of the fuse between your thumb
and index finger and pull straight out.
Be sure to use the correct fuse.
If you ever have a problem on the road and
don’t have a spare fuse, you can “borrow” one of the correct value. 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 of the value you need. Replace it
as
soon as you can. See “Fuses and Circuit Breakers” in the Index for more
information.
