Fuses and Circuit Breakers
The wiring circuits in your car 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.
You’ll find some spare
fuses in the fuse block. 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
car 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.
The fuse panel
is located under the instrument panel,
next to the parking brake.
To release and lower the fuse
panel, squeeze the two tabs together. Then, pull it
towards you.
It will come down so the fuses can be
accessed.
c m
k
Remove the cover to access the fuses.
270

To put the fuse panel back to its original position,
squeeze the two tabs together and push the panel up.

This fuse chart shows how to tell a blown fuse from a
good fuse.
There are additional fuses located behind the right sound
insulator panel on the passenger side. If these require service, see your Buick dealer.
Maxifuse/Relay Center
To check the fuses in this underhood fuse center, turn
the two knobs 1/4 turn counterclockwise and remove the
cover. The inside
of the cover has a chart that explains
the features and controls governed by each fuse and
relay.
The PASS-Key fuse is located in the right side relay center.
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.

INSPECTION OR SERVICE
Brake System
Inspection
WHAT SHOULD BE DONE
Inspect the complete system. Inspect
brake lines and hoses for proper hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads
for wear and rotors for surface
condition. Inspect other brake parts, including calipers, parking brake,
etc. Check parking brake
adjustment.
You may need to have
your brakes inspected more often
if
your driving habits or conditions
result in frequent braking.
NOTE:
A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced. Also,
if the
brake system warning light stays on
or comes on, something may be
wrong with the brake system. See
“Brake System Warning Light” in
the Index. If your anti-lock brake
system warning light stays
on or
comes on, something may be wrong
with the anti-lock brake system. See
“Anti-Lock Brake System Warning
Light” in the Index.
