by the addition of air vent provi­
sions in each quarter panel on sta­
tion wagon and panel express
models and each rear lock pillar
on notchback and hatchback mod­
els. Another feature of the system
is continuous low-speed operation
of the heater and air conditioner
blower, resulting in an uninter­
rupted supply of outside air
flow
into the car whenever the ignition
switch
is on. Generally,
with the side windows
closed, outside· air will
flow into
the front grilles, through the car
and out the rear grilles
or lock pil­
lar grilles. When the side windows
are partially open, under some con­
ditions air will
flow into the car
through both front and rear grilles
and out the side windows.
Basic Operating Tips:
• Always keep front and rear
grilles clear of obstructions
, (leaves, ice, snow, etc.).
2-20
• Always keep underseat air path,
and interior trunk lid and quar­
ter panel grilles clear of ob­
structions.
• When heating or air condition­
ing
is desired, best comfort is
attained by driving with all win­
dows closed.
The following sections of this
manual provide additional operat­
ing tips for obtaining maximum
heating and cooling comfort.

also Engine Exhaust Gas Caution
at beginning of this Section.)

The windshield defrosting and
defogging systems assist
in provid­
ing good visibility through specific
areas of the windshield under most
inclement weather conditions. For
immediate operation of the vehicle,
the windshield,
if necessary, should
be scraped clear.

(Upper Control Lever)
When this lever is in the OFF
HEATER
(
posItion, unheated outside air is
directed up under the instrument
panel.
Pushing this lever to the r!ght
to HEATER position allows air to
move through the heater outlet with
some air
flow to the defroster.
Further movement of this lever to
the right directs the air
flow through
the defroster outlets
as desired when
windshield defrosting
is needed with
some air
flow to the heater outlet.

Temp
Adjust the TEMP control (lower
lever)
as required to give the desired
degree of
heat Full right position of
this lever provides maximum heat.
Fan
The fan lever has (3) three posi­
tions from
LO at the bottom to HI
at the top. Operate system for
30
seconds in HEATER position be­
fore placing upper lever
to DEF;
This will remove humid air from
the system
and minimize rapid
fogging of the glass which can
occur
if humid air is blown onto
a cool windshield.
NOTE: Whenever the ignition
switch
is turned ON, the blower
motor
will automatically operate
at
LO, MED, or HI-depending on
switch setting. There
is no OFF
position.

Downloaded from www.Manualslib.com manuals search engine Heater Operating Tips
• Clear snow and ice from hood
and air inlet in front of wind­
shield and air vent grille in rear
fender,
or roof side panel to im­
prove heater and defroster
effi­
ciency and reduce the probability
of fogging on inside of wind­
shield.
• Clear windshield, rear window,
outside m.irrors and all side win­
dows of ice and snow before
driving vehicle.
• Operate blower on "HIGH" for
a
few seconds before moving the
vehicle, to help clear the intake
ducts of snow to further reduce
the possibility of fogging on in­
side of windshield.
• Keep all windows and vents
closed to reduce dust, road and wind
noise and uncomfortable
drafts.
• For most satisfactory heater
operation and air circulation,
operate fan on low or medium
speeds for normal operation and
high speeds for quick warm-up
and during extremely low tem­
peratures.
• For adequate rear seat heating,
the area beneath the front seat
must not be blocked by carpet­
ing, rags, paper or other material
and fan should operate on high
blower.
Electro-Clear Rear Window
Defogger
The optional defogger may be
turned on after the engine
is run­
ning by lifting the
"ON" switch on
the instrument panel. Power
is in­
dicated by an amber light. After
the defogger has operated between
10 to 15 minutes, the system will
2-22
automatically shut off. If further
defrosting or defogging
is desired,
simply lift the
"ON" switch again.
The defogger will not function
if the engine stalls or the ignition
is turned off.
NOTE: Refrain from removing
decals
or other material from the
inside of rear window with a razor
or other sharp instrument since this
may damage the heating element.

Selector Lever Operation
OFF -Outside air is discharged
through the heater outlet at low
blower speed. The blower remains
operative with ignition switch
ON.
MAX-Air from the passenger com­
partment
is recirculated through
the system and discharged from the
AIC outlets when the selector lever
is in the MAX cold position. The
blower will automatically go to
HI
only position. This is' to prevent
inadvertent driving for extended
periods with the system on recircu­
lated air. The MAX position
is
used when maximum cooling is
req uired under conditions of high
temperature and humidity.
NORM -Outside air is passed
through the
AIC outlets -This
