2000 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
40
F (4.5
C). You may notice a delay of three to four
minutes before the fan comes on.
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 blower will be at low speed momentarily
and then go to the high speed. The air intake will be
recirculated for maximum cooling performance. As the
interior of the vehicle cools down to your desired
comfort point, the blower will decrease and the
temperature door will move to a warmer position to
maintain your desired comfort. 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 blower will start out at a low speed and the
blower 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 your desired comfort level, the
blower will decrease and the temperature door will
move to a cooler position to maintain your desired
comfort. 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.

3-8
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 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. Please note that
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 40
F (4.5
C). (Even when the
compressor is running, you can control the temperature).
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 40
F (4.5
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. Also, note that 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.

3-9
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 A/C button (if equipped)
pushed in. 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.
You can use BI
-LEV with the A/C button (if equipped)
pushed in. 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.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use UPPER, ECON (if equipped) and
OUTSIDE AIR to direct outside air through your
vehicle. Your vehicle also has the flow
-through
ventilation system described later in this section.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use your
DEFROST button. To warm passengers while keeping
the windows clean, use DEFOG by pressing the
MODE button.

3-11 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.

7-21 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.
Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear. Do not lubricate accelerator and
cruise control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook
-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or conditions
result in frequent braking.
