1996 CHEVROLET EXPRESS air condition

Downloaded from www.Manualslib.com manuals search engine Rear Heater (Without Air Conditioning)
If you have a rear heater (without rear air conditioning),
the control switch
is located on the instrument panel.
To increase and decrease the flow of heated air to the
rear floor vents, move the switch marked
REAR HEAT
to the blower speed you want.
The knob has three speed positions.
To increase the flow
of heated air, move the switch toward HIGH. To turn the
fan
off, move the switch to OFF.
Rear Air Conditioning and Rear Heater
If your vehicle has a rear air conditioning and rear heater
system combination, controls are provided to regulate the
temperature, location
and speed of the air flow.
Front Passenger Control
To adjust the air temperature, turn the temperature knob
on the right side of the control panel.
For warmer air, turn the knob clockwise toward the red
area, and for cooler air, turn the knob counterclockwise
toward the blue area.

Downloaded from www.Manualslib.com manuals search engine To regulate the airflow location, adjust the center knob
on the control panel. Turn the knob counterclockwise
for floor vent air flow or clockwise for headliner
vent air
flow. Generally, the upper vents are used for air
conditioning and the floor vents for heating. The control
knob can be set to any blend setting.
To adjust the air flow speed, turn the fan control knob
on
the left side of the control panel to the desired
blower setting.
To activate the rear control, move the fan knob on the
front control
to REAR CNTL.
The rear control works just like the front control. It will
allow second seat passengers to adjust the controls as
they desire.

Before using your vehicle’s air conditioning, open the
windows to clear the vehicle of hot air. This reduces the
time
it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner
to work at
its best.
You can use MAX A/C with the temperature knob in the
blue area, when it’s really hot outside and you need to
cool the inside air quickly. MAX A/C lets in only a little
air from the outside.
If you first use
MAX A/C, you can then use A/C with
the temperature knob
in the blue area, as soon as the
vehicle has cooled down,
so outside air will be going
through your vehicle.
If your vehicle has rear air conditioning, setting it on LO
may enhance front A/C performance by allowing
trapped refrigerant
in rear lines to circulate.
When the air conditioning, DEFROST or
BLEND is on,
you may notice a slight increase or decrease in engine
speed, due
to compressor operation. This is normal
because the system is designed
to cycle the compressor
on and off to keep the desired temperature.
Heating
On cold days, use HEATER with the temperature knob
in the red area. Outside air will be brought in through
the floor outlets. The heater works best if
you keep your
windows closed while using
it.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air ftdster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.

Downloaded from www.Manualslib.com manuals search engine If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer
the way you want the
vehicle to go.
If you start steering quickly enough, your
vehicle may straighten
out. Always be ready for a
second skid if it occurs.
Of course, traction
is reduced when water, snow, ice,
gravel or other material is
on the road. For safety, you’ll
want
to slow down and adjust your driving to these
conditions. It is important
to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on
a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting
to a
lower gear). Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your vehicle is skidding. Learn to recognize
warning clues
-- such as enough water, ice or packed
snow on the road to make a “mirrored surface”
-- and
slow down when
you have any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid
only the braking skid.
Driving at Night
Night driving is more dangerous than day driving.
One reason is
that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems, or by fatigue.

If you get the overheat warning but see or hear no
steam, the problem may
not be too serious. Sometimes
the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer. See “Driving on Grades” in the Index.
If
you get the overheat warning with no sign of steam,
try this for a
minute or so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift
to the highest gear while
driving
-- DRIVE (D).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back on,
you can
drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked,
to push
the accelerator until the engine speed is about twice as
fast as normal idle speed. Bring
the engine speed back to
normal idle speed after two or three minutes. Now see
if
the warning stops. But then, if you still have the
warning,
turn ofthe engine and get everyone out qf the
vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.

this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure the
arrows
on the pressure cap line up like this.
Engine Fan Noise
Your vehicle has a clutched engine cooling fan. When the
clutch is engaged,
the fan spins faster to provide more air
to cool the engine. In most every day driving conditions,
the fan
is spinning slower and clutch is not fully engaged.
This improves fuel economy and reduces fan noise.
Under heavy vehicle loading, trailer towing and/or high
outside temperatures, the fan speed increases
as the clutch
more
fully engages. So you may hear an increase in fan
noise. This
is normal and should not be mistaken as the
transmission slipping
or making extra shifts. It is merely
the cooling system functioning properly. The fan will
slow down when additional cooling is not required and
the clutch partially disengages.
You may also hear this Fan noise when you start
the engine. It will go away as the fan clutch
partially disengages.

Downloaded from www.Manualslib.com manuals search engine If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it
is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp
on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test.
If this occurs, return to your
authorized GM dealer for diagnosis to determine the
cause
of hilure. In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may
not be covered by your warranty.
In Canada, some gasolines contain an octane-enhancing
additive called
MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp
on your instrument
panel
may turn on. If this happens, return to your
authorized GM dealer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming
in your engine and fuel system, allowing your
emission control system to function properly. Therefore,
you should
not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available
in your area to help clean the air. General
Motors recommends that
you use these gasolines if they
comply with the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it.
It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

Downloaded from www.Manualslib.com manuals search engine If your vehicle has a 7.4L engine and air conditioning,
your vehicle will have
a auxiliary engine fan in addition
to the belt driven fan.
A CAUTION:
If your vehicle has air conditioning, the auxiliary
engine fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools
away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.
Before closing the hood, be sure all the filler caps are
on properly.
Then lift the hood to relieve pressure
on the hood prop.
Remove the hood prop from the slot in the hood and
return the prop
to its retainer. Then just let the hood
down and close
it firmly.
Noise Control System
The following information relates to compliance with
Federal noise emission standards for vehicles with a
Gross Vehicle Weight Rating (GVWR) of more than
10,000
lbs. (4 536 kg). The Maintenance Schedule
booklet provides information on maintaining the noise
control system
to minimize degradation of the noise
emission control system during the life of your vehicle.
The noise control system warranty is given
in your
Warranty booklet.
These standards apply
only to vehicles sold in the
United States.
