1994 OLDSMOBILE BRAVADA wiring

If the green arrows don’t go on at all
when
you signal a turn, check the fuse
(see the
Index under Fuses G Circuit
Breakers) 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.
Windshield Wipers
You control the windshield wipers by
turning the band marked WIPER.
For a single wiping cycle, turn the band
to
MIST. Hold it there until the wipers
start, then let go. The wipers will stop
after one cycle. If you want more cycles,
hold the band on
MIST longer. You
can set the wiper speed for a long
or short delay between wipes. This can
be very useful in light rain or snow.
Turn the band to choose the delay time.
The closer to
LO, the shorter the delay.
For steady wiping at low speed, turn the
band away from you
to the LO position.
For high speed wiping, turn the band
further, to
HI. To stop the wipers, move
the band to
OFF.
Remember that damaged wiper blades
may prevent you from seeing well enough
to drive safely.
To avoid damage, be sure
to clear ice and snow from the wiper
blades before using them.
If they’re
frozen
to the windshield, carefully loosen
or thaw them.
If your blades do become
damaged, get new blades or blade inserts.

Your Driving and the Road
Turn Signals When Towing a
Trailer
When you tow a trailer, your vehicle has
to have a different turn signal flasher
and extra wiring. The green arrows on
your instrument panel will flash
whenever you signal a turn or lane
change. Properly hooked up, the trailer
lights will also flash, telling other
drivers you’re about to turn, change
lanes or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think
drivers behind you are seeing your
signal when they are not, It’s important
to check occasionally to be sure the
trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift
down, you
might have to use your brakes
so much
that they would get hot and no longer
work well. On
a long uphill grade, shift down and
reduce your speed
to around 45 mph
(70 km/h) to reduce the possibility of
engine and transmission overheating.
If you are towing a trailer that weighs
more than
3,000 pounds (1 350 kg), it’s
best to drive in
D instead of Overdrive
(or, as you need to, a lower gear). This
will minimize heat build-up and extend
the life of your transmission.
Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a hill.
If
something goes wrong, your rig could
start to move. People can be injured,
and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on
a hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
P (Park) yet.
2. Have someone place chocks under
the trailer wheels.
3. When the wheel chocks are in place,
release the regular brakes until the
chocks absorb the load.
4. Reapply the regular brakes. Then
apply your parking brake and then
shift to
P (Park).
5. Release the regular brakes.
When You Are Ready to Leave
After Parking on
a Hill
1. Apply your regular brakes and hold
the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear
4. Stop and have someone pick up and
of
the chocks.
store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more
often when you’re pulling a trailer. See
the Maintenance Schedule for more on
this. Things that are especially
important in trailer operation are
automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt,
cooling system, and brake adjustment.
Each of these is covered in this manual,
ProCarManuals.com

and the Index will help you find them
quickly. If you’re trailering, it’s a good
idea to review these sections before
you
start your trip.
Check periodically to see that all hitch
nuts and bolts are tight.
See the next section,
Trailer Wiring
Harness.
Trailer Wiring Harness (OPTION)
Your Bravada is equipped with a 7-wire
trailer harness with a 30-amp battery
feed wire. It’s stored under the vehicle
along the rear frame crossmember.
Since connectors for trailers vary, no
connector is provided.
You will need to
obtain one for the trailer
you want to
pull. Have it wired to the harness by a
qualified service technician.
When wiring the harness to a
connector, disconnect the battery before
removing the tape from the wire. The
wire applications are:
White-Ground
Dark green-Right turn signal
Yellow-Left turn signal
Brown-Rear lamps
Light green-Back-up lamps
Red-Battery charging
Blue-Trailer brakes, auxiliary
In use, tape or tie the harness to your
vehicle’s frame rail. Leave enough slack
so the wiring doesn’t bend or break, but
not
so much that it drags on the
ground.
When it’s not in use, fold the harness
neatly and wrap or tie it. Store in the
original place along the frame
crossmember.

I Add-on Electrical
Equipment
NOTICE:
Don’t add anything electrical to
your Oldsmobile 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.
I Fuses & Circuit Breakers
The fuse block is under the instrument
panel
on the driver’s side. It is covered
by an access panel.
The wiring circuits
in your vehicle 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
damage caused by electrical problems.
To Remove the Access Panel:
1. Remove the hex-head screw.
2. Pull down and out on the access
panel.
U
I
Look at the silver-colored band inside
;he fuse. If the band is broken or
nelted, replace the fuse. Be sure you
replace a bad fuse with a new one of the
:orrect size.
To Install the Access Panel:
1. Put the access panel tab into the slot
2. Install the screw.

Headlight Wiring
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 system checked right away.
Trailer Wiring Harness
The seven-wire trailer wiring harness is
protected by an in-line fuse in the
battery feed wire. This fuse is near the
junction block. See the
Index under
Trailer Wiring Harness.
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
Accessories
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.
Before you wire any other electrical
accessories into your fuse block, please
check with your Oldsmobile dealer.
