2001 Oldsmobile Intrigue air conditioning

3-6
Auto Button
For the most efficient operation you should press
the AUTO button and set the system temperature.
The system will select the best fan speed and airflow
settings to keep you comfortable. The air conditioning
compressor will run if the outside temperature is above
38
F (3.3
C). You may notice a delay of three to
four minutes before the fan comes on. For the automatic
system to function, the temperature must be set between
61
F (16
C) and 89
F (31
C).
Hot Weather Example: When you start the vehicle in
hot weather, 80
F (27
C) or after being parked during
the day in full sun, if your Driver Set Temperature is
73
F (23
C) and you are in full automatic mode, the
system will automatically move the temperature doors to
full cold. The fan will be at low speed momentarily and
then go to high speed. The air intake will be recirculated
for maximum cooling performance. As the interior of
the vehicle cools down to the desired comfort point, the
fan speed will decrease and the temperature door will
move to a warmer position to maintain the desired
comfort level. As the cabin cools down or the sun load
decreases, the system could switch to air delivered to
A/C vents and the floor (Bi
-level mode).Cold Weather Example: When you start the vehicle in
cold weather, (below freezing), or after being parked
overnight, if your Driver Set Temperature is 73
F
(23
C) and you are in full automatic mode, the system
will automatically move the temperature doors to full
hot. The fan will start out at a low speed and the fan
speed will increase as the engine warms up. The air will
be delivered to the floor. As the interior of the vehicle
warms up to the desired comfort level, the fan speed will
decrease and the temperature door will move to a cooler
position to maintain the desired comfort level. As the
cabin warms up or the sun load increases, the system
could switch to air delivered to the windshield and the
floor (DEFOG mode).
Off Button
Push the OFF button to turn the system off. The display
will show OFF and outside temperature.

3-7 Manual Control of the Automatic System
If you prefer to manually control the heating, cooling
and ventilation in your vehicle, set the system to the
temperature and fan speed you want. Next, push the
mode button to select your desired airflow direction.
The system will try to maintain the temperature you set
using the mode you select. The following suggestions
will help the system run more efficiently in manual mode.
Fan Button
: The button below the display is used to manually
select the force of air you want. The display will show
the fan speed. Fan control is no longer automatic, but
the system remains in auto temperature control.
If the airflow seems very low when the fan knob is turned
to the highest setting regardless of the mode setting, your
passenger compartment air filter (if equipped) may need to
be replaced. See ªMaintenance Scheduleº in the Index.
Econ Button
Press the ECON button to turn the compressor on and
off. The indicator light is illuminated when the
compressor is off. AUTO will be not be illuminated, but
the system will maintain automatic air delivery and fan
speed control. The system will attempt to control the
temperature without the help of the compressor.Mode Button
The MODE button is used to control the direction of
airflow when the system is not in AUTO. The first press
will display the current airflow direction. Repeated
pressing will cycle through the following air flow
directions shown in the display.
UPPER: This setting directs air through the
instrument panel outlets.
BI-LEV: This setting directs air two ways. Half of
the air is directed through the instrument panel outlets.
Most of the remaining air is directed through the floor
ducts and a little to the defrost and side window vents.
LOWER: This setting sends most of the air
through the ducts near the floor. The rest comes out of
the defrost and side window vents. When using this
mode and RECIRC, the windows may fog up when the
weather is cold and damp. See ªRecirculationº in the
Index for more information.
DEFOG: This setting allows half of the air to go
to the floor ducts and half to the defrost and side
window vents. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below 38
F (3.3
C). (Even when the
compressor is running, you can control the temperature).

3-8
DEFROST: This setting directs most of the air
through the defrost and side window vents. Some of
the air goes to the floor ducts. The air conditioning
compressor will run automatically in this setting unless
the outside temperature is below 38
F (3.3
C).
(Even when the compressor is running, you can control
the temperature).
RECIRC: This setting recirculates the air inside
of your vehicle. This setting is not available in defog or
defrost mode. When operating the system in the
RECIRC mode, the windows may fog up when the
weather is cold and damp. To clear the fog, select either
the DEFOG or DEFROST mode and increase the fan
speed. To avoid re
-fogging of the windows, use the
OUTSIDE AIR mode.
OUTSIDE AIR: This setting brings in outside air.
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time the
compressor has to run, which should help fuel economy.
For quick cool
-down on very hot days, use UPPER and
RECIRC. If this setting is used for long periods of time,
the air in your vehicle may become too dry.For normal cooling on hot days, use UPPER and
OUTSIDE AIR with the compressor on. The system will
bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. To
remedy this, you can use BI
-LEV with the compressor
on. The system will bring in outside air and direct it to
your upper body, while sending slightly warmed air to
your lower body. You may notice this temperature
difference more at some times than others.
Heating
On cold days use LOWER. The system will bring in
outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.

3-10 Ventilation System
Adjust the direction of airflow by moving the vents. To
completely shut off airflow to the outlet move the
thumbwheel down. To open the outlet for airflow move
the thumbwheel up.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction, such as leaves. The heater and
defroster will work far better, reducing the chance of
fogging the inside of your windows.

When you enter a vehicle in cold weather, set the
mode to FLOOR or LOWER and the fan to the
highest speed for a few moments before driving off.
This helps clear the intake ducts of snow and
moisture and reduces the chance of fogging the
inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

Part C: Periodic
Maintenance Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,
each spring and fall). You should let your dealer's
service department or other qualified service center do
these jobs. Make sure any necessary repairs are
completed at once.
Proper procedures to perform these services may be
found in a service manual. See ªService and Owner
Publicationsº in the Index.
Steering, Suspension and Front Drive Axle
Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook
-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the
drive axle boot seals for damage, tears or leakage.
Replace seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out
-of-position parts as well as open seams,
holes, loose connections or other conditions which could
cause a heat build
-up in the floor pan or could let
exhaust fumes into the vehicle. See ªEngine Exhaustº in
the Index.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the outside
of the radiator and air conditioning condenser. To help
ensure proper operation, a pressure test of the cooling
system and pressure cap is recommended at least
once a year.
