Automotive Air Conditioner Controls
(with Type 1 Fan Switch)
Clear windshield, rear window, outside mir-
ror, and all side windows of ice and snow
before driving vehicle .
Operate blower on "HI" for a few seconds
before moving the vehicle, to clear the air
intake of snow.
AUTOMOTIVE AIR CONDITIONER
The Automotive Air Conditioning System
offers year-round driving comfort. In addition to
providing circulation of cool air during hot
weather, the system can provide warm air in
cold weather and dehumidify outside air in
humid weather.
Combined air conditioning and heating sys-
tem controls are located on the instrument panel
in the upper right-hand corner. There are three
separate controls; "FAN" lever, to control speed
of blower ; "OFF," "A/C,99 "VENT," "HEATER,"
"DEF" lever to control direction of air flow and
which system is to be operated ; "RECIRC,"
"COLD," "HOT" lever to control the tempera-
ture of the air. The three levers may be placed
in many combined positions to deliver the cli-
mate conditions most desirable at any given
time.
TYPE 1 "FAN"-The fan switch has four
positions ; "OFF" and three blower speeds
ranging from "LO" to "HI." The fan will not
operate unless the top lever has been moved
from the "OFF" position, and in order to
operate the fan in the "HI" position the
engine must be running.
TYPE 2 "FAN"-The fan switch has four
positions; "LO" and three blower speeds
ranging to "HI." Fan will operate whenever

the key is in the "RUN" or "ACCESSORY"
position. In order to operate the fan in the
"HI" position the engine must be running.
"OFF," "A/C," "VENT," "HEATER," "DEF"
-With the lever in the "OFF" position the
system is off. With the lever in the "A/C"
position (and the "RECIRC," "COLD,"
"HOT" lever at "RECIRC" position) the air
conditioning system is activated and the
blower automatically goes to "HI" speed pro-
viding the engine is running. This position
uses 80% recirculated air. This setting will
provide maximum cooling . In combination
with "A/C" setting moving the tempera-
ture lever to the "COLD" position provides
100% outside air. Further movement of the
temperature lever to the right (toward
"HOT" position) will heat the dehumidified
air to the desired temperature . The "FAN"
switch can be set to meet air flow require-
ments .
With the lever in the "VENT" position,
100% outside air enters the driver's com-
partment. This setting is for use during peri-
ods of less severe heat and humidity, air flow
is identical to air flow in "A/C" position, how-
ever, the air conditioning compressor is not
operating. Temperature of incoming air may
be controlled by moving the temperature
lever to the desired position . Any one of the
blower speeds may be selected.
With the lever in the "HEATER" position,
air will flow through the heater floor dis-
tributor outlets (with a slight flow of air to
the defroster outlet) . For maximum heat,
move the temperature lever to "HOT" posi-
tion and "FAN" switch lever to "HI" position .
