fuses CHEVROLET SUBURBAN 1994 Owners Manual

Turn Signal and Lane Change lndicator
The turn signal has
two upward (for right
signal) and two
downward
(for left
signal) 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 don’t flash but just stay
on, 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 for burned-out bulbs
and a blown fuse (see “Fuses” in
the Index).

4. Remove the
screws from the
bulb retainer and
take the bulb
retainer
off of the
light assembly.
5. Pull the old bulb
straight out
of the
socket.
6. Put in a new bulb and push it in until it is tight.
7. Replace the bulb retainer.
8. Replace the rear light assembly and tighten the screws. You may want
to use
a magnetic screwdriver when installing the screws.
9. Close the tailgate or rear doors.
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.
The headlight wiring is protected by
a circuit breaker in the light switch. An
electrical overload
will cause the lights to flicker 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. Although
the circuit is protected from electrical overload,
overload due to heavy snow, etc., may cause wiper linkage damage. Always
clear ice and heavy snow from the windshield before using the windshield
wipers.
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. This protects the circuit until the current load returns to
normal or the problem is fixed
.
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.
Fuse Block
The fuse block is
behind an access door
at the bottom
of the
instrument panel, next
to the parking brake
release lever.
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.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle if you notice:
Engine misfiring
Loss of performance
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three- Way Catalytic Converter (gas engines)
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Three- Way Catalytic Converter (diesel engines)
Your vehicle’s three-way catalytic converter is designed to reduce the
particulates in your vehicle’s exhaust. If your vehicle’s three-way catalytic
converter ever needs to be replaced, it must be replaced with a three-way
catalytic converter intended for use with diesel engines only.
Engine Contro/ Module System (All T61 equipped
vehicles and diesel engine vehicles below
8,500 lbs. GVWR)
Gasoline Engines
This system has an oxygen sensor (02) that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle. If
you use leaded fuel, you could damage your oxygen sensor
(02) and
three-way catalytic converter.
Diesel Vehicles Below S,5UU LBS. GVWR
This system monitors engine speed and throttle position. It adjusts exhaust
gas recirculation to limit emissions.
