Buick Roadmaster - 1996 Fuse Box Diagram

I1
Your vehicle is equipped
with the PASS-Key
I1
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
11
is a passive
theft-deterrent system.
It
works
when
you
insert
or remove
the
key
from
the ignition.
PASS-Key
11
uses a resistor pellet in the ignition key
that
matches a decoder in
your
vehicle.
When
the
PASS-Key
II
system
senses
that
someone
is
using
the
wrong
key,
it
shuts
down
the
vehicle’s
starter
and
fuel
systems.
For
about
three
rninutes,
the
starter
won’t
work
and
fuel
won’t
go
to
the
engine.
If
someone
tries
to
start
your
vehicle
again
or
uses
another
key
during
this
time,
the
vehicle
will
not
start.
This
discourages
someone
fiom randomly
trying
different
keys
with
different
resistor
pellets
in
an
attempt
to
make
a match.
The ignition key
must
be clean and
dry
before
it’s
inserted in the ignition or the engine may not start.
If
the
engine does
not start and the PASS
KEY light comes
on,
the key may be dirty or wet.
Turn the ignition
off.
Clean
and
dry
the key.
Wait
about
three rninutes
and
try
again. The PASS
KEY
light may remain on
during this
time. If the starter still won’t
work,
and
the key
appears
to be clean and
dry,
wait
about three minutes
and
try
another ignition key.
At
this
time,
you
may
also
want
to
check the fuse (see “Fuses
and
Circuit Breakers” in the
Index).
If
the starter won’t
work
with
the other
key,
your
vehicle needs service.
If
your
vehicle
does
start, the first
ignition key
may be faulty. See your
Buick
dealer
or
a
locksmith
who
can
service the PASS-Key
II.

Turn
Signal
and
Lane
Change
Indicator
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.
An
arrow
on
the
instrument
panel
will
flash
in the
To
signal
a
lane change, just raise
or
lower
the
lever
until
the
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
arrows
don’t
go
on
at all
when
you
signal
a
turn,
check
for
burned-out
bulbs
and
check
the
fuse
(see
Fuses
and
Circuit
Breakers”
in
the
Index).
If
you have a
trailer
towing
option
with
added
wiring
for
the trailer
lamps,
a
different
turn
signal
flasher
is
used.
With
this
flasher
installed,
the
signal
indicator
will
flash
even
if
a
turn
signal
bulb
is burned
out.
Check
the
front
and
rear
turn
signal
lamps
regularly
to make
sure
they
are
working.
A
chime
will
sound
if
your
turn
signal
remains
on after
having
driven
1/2
mile
(0.8
km),
to
remind
you
to
turn
off
your
signal.
Headlamp Highbow Beam
Changer
To change
the
headlamps
from low
beam
to
high
or
high
to
low,
pull
the
turn
signal
lever
all
the
way
toward
you.
Then
release
it.
When
the
high
beams
are
on,
this
light
on
the
instrument
panel
will
also
be
on.

Using
A
Weight-Carrying
Trailer
Hitch
(Recommended for loaded
trailers
weighing
less
than
3,009
lbs. or
1
362
kg.)
Your vehicle is equipped
with
an
Electronic
Level
Control
(ELC)
feature.
When
hooking
up
a
trailer
using
a
weight-hstributing hitch,
always
use
the
following
procedure:
The
trailer
tongue
should
weigh
10
percent of
the
total
trailer
load
(maximum
300
lbs.
or
136
kg)
or
as
specified by the
trailer
manufacturer
to
minimize
sway.
should
be
equipped
with
trailer
brakes.
0
Trailers
that
weigh
more
than
1,000
lbs.
(454
kg)
Consider
using
sway
control
if
your
loaded
trailer
will
weigh
3,000
lbs. (1 362
kg)
or
more.
Trailer
Hitching
Procedure
Using
A
Weight-Distributing
(Equalizing)
Hitch
(Recommended
for
loaded
trailers
weighing
3,000
lbs.
to 7,000 lbs.
or
1
362 kg to 3
178
kg.)
Using
a
weight-distributing
hitch
without
disabling
the
Electronic
Level
Control
(ELC)
system
may
defeat
the
purpose of the
weight-distributing
hitch.
Also,
your
rear
tires
may
become
overloaded.
A
weight-distributing
hitch
should
spread
the
load
to
all
axles.
If
you
use
a
weight-distributing
hitch,
always
disable
the
ELC by
following
the
proper
steps.

surface
without
the
trailer
hitched.
With
the
ignition
off,
and
all
doors
closed,
allow
the
vehicle
to
level
automatically.
Disable
the
Electronic
Level
Control
(ELC)
by
pulling
the
LEVEL

fuse from the
underhood
electrical
center
located
on
the passenger-side
wheel
housing
in
the
engine
compartment.
Remove
the
cover
to
gain
access.
Attach
the
trailer
to
the
vehicle.
The
trailer
tongue
sh
weigh
12
percent of the
total
loaded
trailer
weight.
Level
the
vehicle
with
the load-leveling
spring
bars
(equalizers).
Leave
the
fuse
out
while
towing
your
trailer.
Once
you
have
completed
towing
your
trailer,
be sure
to
reinstall
the
Electronic Level Control
(ELC)
fuse.
Electrical

Add-on Electrical
Equipment
I
NOTICE:
Don’t
add
anything
electrical
to your
Buick
unless
you
check
with
your
dealer
first.
Some
electrical
equipment
can
damage
your
vehicle
and
the
damage
wouldn’t
be
covered
by
your
warranty.
Some
add-on
electrical
equipment
can
keep
other
components
from
working
as
they
should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Buick, see “Servicing
Your Air Bag-Equipped
Buick” in
the
Index.
Headlamps
The
headlamp
wiring
is protected
by
an
internal
circuit
breaker. 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
Wipers
The windshield
wiper
motor
is protected by
an internal
circuit breaker and a fuse. If the motor
overheatsdue 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 fixed.
Power
Windows
and
Other
Power
Options
Circuit breakers 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.
6-55
*xes
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.
This
greatly
reduces
the
chance of fires
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
you
replace
a
bad fuse with
a
new one of the
identical
size
and
rating.
I
If
you
ever
have
a
problem
on
the
road
and
don’t
have
a
spare fuse,
you
can
borrow one
of
that
has
the
same
amperage.
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 the
correct
amperage.
Replace it as
soon
as
you
can.
There
are
two
fuse
blocks
in
your
vehicle:
the
instrument
panel fuse block
and
the
engine
compartment
fuse
block.
Instrument
Panel
Fuse
Block
To
gain
access
to
this
fuse block,
remove
the
cover
on
the
driver’s
side of the
instrument
panel.
Make
sure
to
insert
the
tabs
first
when
replacing
the
cover.
