The system, being completely automatic, may be set at a
comfortable temperature and left with virtually no adjust-
ments required due to outside weather conditions. In cold
weather the system will provide heat automatically when
engine coolant is warm enough; and when outside tempera-
tures are high, the system will provide air conditioning
automatically.
In warm weather, cooled, dehumidified air is discharged
from five adjustable outlets—two at each end and one in the
center of the instrument panel. On all models except the
Fleetwood Seventy-Five sedan and limousine, a separate ven-
tilation feature is provided to admit outside air directly into
the passenger compartment through these outlets.
In cool weather, warm air (as high as 90° F.) may be emitted
from the five outlets. Each outlet can be rotated to direct air
throughout the car. The vanes in the end outlets can be set
to direct air flow in any direction by positioning the knob on
each outlet in the direction you wish the air to flow. The end
outlets can be closed by moving the knobs toward each other.
The center outlet can be closed or set to direct air flow up or
down by rotating the vaned outlet. Also, one side of the outlet
discharges a concentrated stream of air; the other side, when
rotated 180°, spreads the air over a wider area.
In cold weather, heated air enters the front passenger com-
partment through grilles and openings in front of the dash
panel. Heated air is delivered to the rear passenger compart-
ment through ducts that extend rearward under the front
carpet and seat. Part of the heated air may be directed to the
windshield for removing fog or ice.
Individually controlled front and rear systems are used on
the Fleetwood Seventy-Five sedan and limousine. Operating
instructions for the front system as explained in this section,
with the exception of the ventilation feature, also apply to
Fleetwood Seventy-Five cars.
The rear system is a completely separate system with a
large heater, blower and evaporator assembly mounted in the
trunk. Operating instructions for the rear system are explained
in Section 3, beginning on page 44.
CONTROLS
The control panel for Automatic Climate Control is located
just below the instrument cluster to the right of the ignition
switch.
NORMAL OPERATION
1. Set the temperature dial on the control panel to the
interior temperature desired.
2. Position horizontal sliding lever at the white triangle
above the word "AUTO". This turns the system on, providing
100% outside air at all times and automatically controls heating,
air conditioning and blower speeds.
