Cadillac eldorado 2001 User Manual

If your vehicle is sitting out on a hot day and you have 
it set on AUTO, the air will first flow out the floor air
outlets for a few seconds. That is normal. This is to
expel hot air from the air outlets. As the air is cooled,
the airflow will move through the air conditioning
outlets. If you start your vehicle with the fan setting 
on HI, it will skip the air conditioning purge.

To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the coolant warms
up, the blower fan speed will gradually increase and air
will flow from the heater outlets, with some airflow 
to the windshield to prevent fogging under most 
normal conditions.

If you leave your vehicle, the system will remember the
control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas, DEFROST will change
to automatic operation when the ignition is shut off and
then turned back on.

You may manually adjust the air delivery mode or 
fan speed.

LEVEL: This setting directs air into your

vehicle in two ways. Cool air is directed to the upper
portion of your body through the four instrument panel
outlets while warmed air is directed to the floor.

HEATER/DEFROST: This setting directs air 

to the floor outlets and toward the windshield.

HEATER: This setting directs warmed air

through the floor outlets. Some warm air is diverted to
the windshield to minimize fogging.

DEFROST: Press this button to quickly remove

fog or frost from the windshield. This setting sends 
most of the airflow to the windshield with only a small
amount to the floor outlets.
