Buick Roadmaster - 1994 Fuse Box Diagram

Buick Roadmaster - 1994 Fuse Box Diagram

Your vehicle
is
equipped
with
the
PASS-Key%
(Personalized
Automotive
Security
System) theft
deterrent
system.
PASS-Key%
is
a
passive
theft
deterrent
system. This
means
you
don’t
have
to do anything
different
to ann or
disarm
the
system.
It
works
when
you
insert
or
remove
the
key
from
the
ignition.
PASS-Key%
uses
a
resistor
pellet
in
the
ignition
key
that
matches
a
decoder
in
your
vehicle.
When
the
PASS-Key%
system
senses
that
someone
is
using
the
wrong
key,
it
shuts
down
the
vehicle’s
starter
and
fuel
systems.
For
about
three
minutes,
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
minutes
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
the
other
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
otherkey, 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%.
If
you
accidentally
use a key
that
has a damaged
or
missing
resistor
pellet,
the
starter
won’t
work
and
the
PASS
KEY
light
will
come
on.
But
you
don’t
have
to
wait
three
minutes
before
trying
one
of
the
other
ignition
keys.
See
your h i c k dealer
or
a
locksmith
who
can
service
the
PASS-Key%
to
have
a
new
key
made.
If
you’re
ever
driving
and
and
the
PASS
KEY
light
comes
on
and
stays
on,
you
will
be
able
to
restart
your
engine if
you
turn
it
off.
Your
PASS-Key%
system,
however,
is
not
working
properly
and
must
be
serviced
by
your
Buick
dealer.
Your vehicle
is
not
protected
by
the
PASS-Key%
system.
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 the
fuse
(see
Fuses
in
the
Index)
and
for
burned-out
bulbs.
If
you
have a trailer
towing
option
with
added
wiring
for
the trailer
lights,
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
lights
regularly
to
make
sure
they
are working.
Turn
Signal
Reminder
A chime will
sound
if
your
turn
signal
remains
on
afier
having
driven
1/2
mile, to remind you to
turn
off
your
signal.
Operation
of
Lights
Although
your
vehicle’s
lighting
system
(headlights,
parking
lights,
fog
lamps,
side
marker
lights
and
taillights)
meets all applicable
federal
lighting
requiremeilts,
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
your
fog
lamps
only
when
your
lower
beam
headlights
are
also
on,
or
that
headlights
be
turned
on
whenever
you
must
use
your
windshield
wipers.
In
addition,
most
jurisdictions
prohibit
driving
solely
with
parking
lights,
especially
at dawn
or
dusk.
It
is
recommended
that you check
with
your
own
state
or
provincial
highway
authority
for
applicable
lighting
regulations.
Headlight

Your vehicle
will
need
service
more
often
when
you’re

fluid (don’t
overfill), engine oil, axle
lubricant,
belts,
cooling
system, and brake
adjustment.Each of these
is
covered
in
this
manual,
and

Check
periodically
to
see
that

of
the identical
size
and
rating.
Headlights
The headlight
wiring
is
protected
by a
circuit
breaker
in
the light
switch. Anelectrical 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

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.

is
too
heavy,
the
circuit
