Add-on Electrical Equipment
I NOTICE:
Don’t add anything electrical to your Cadillac 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. Bef‘ore attempting to
add anything electrical to your Cadillac, sce ”Servicing
Your Air Bag-Equipped Cadillac” in the Index.
Headlamp Wiring
The headlamp wiring has an individual fuse which is
powered
by a MaxiFuse@. An electrical overload will
cause the lamps to
go on and off, or in some cases to
remain
off. If this happens, have the headlamp wiring
checked right away.
MaxiFuse
is a registered trademark of Little Fuse
Incorporated.
Windshiek Xper Fuses
The windshield wiper motor is powered by a MaxiFuse.
If the motor overheats due to heavy snow, etc., the
wipers will stop until the motor cools.
If the overload
is caused by some electrical problem, be sure to have
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.

Downloaded from www.Manualslib.com manuals search engine Fuse Id Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination
of fuses and circuit
breakers. 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.
Engine Con tment Fuse Bloc -;
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one that has the same
amperage. 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 three fuse blocks in your vehicle: the engine
compartment fuse block, the MaxiFuse
relay center and
the rear compartment fuse block. The fuse
block is located next to the air filter on the
driver's side of the engine. Lift the cover to gain access.
