Electrical System
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.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. 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 system 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, have
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.
Engine A/C, EGR, Relays, SIR Crank and
Safety Belt Fuses
These fuses are located behind the glove box. The fuse
holders are taped together with gray tape.
Other - uses
The Safety Belt/Chime (ICAM) Module fuse and the
Remote Keyless Entry fuse are located behind the fuse
block, above the hush panel.
The Fuel Pump, A/C CONT and the ECM fuses are
located under the hood.
