7A-2 HEATING AND VENTILATION SYSTEM
DESCRIPTION AND OPERATION
HEATING AND VENTILATION
SYSTEM
The base heater system is designed to provide heating,
ventilation, windshield defrosting, side wind defogging
and rear seat area.
The heater and fan assembly blower regulates the air-
flow from the air inlet for further processing and distribu-
tion.
The heater core transfers the heater from the engine
coolant to the inlet air.
The temperature door regulates the amount of the air
that passes through the heater core. The temperature
door also controls the temperature of the air by control-
ling mix of heated air with the ambient air.
The mode door regulates the flow and distribution of
the processed air to the heater ducts and to the defroster
ducts.
The console mounted heating and ventilation control
panel contains one rotary control knob, one sliding con-
trol lever and six push control knobs, which operate as
follows:
Sliding Temperature Control Lever
•Actuates by cable.
Raise the temperature of the air entering the vehicle
by sliding to the right, or the red portion of the knob.
Five Mode Control Knob
Actuates by electricity.
Regulates the air distribution between the
windshield, the instrument panel, and the floor
vents.
Rotary Blower Control Knob
Turns on to operate the blower motor at four speeds.
Turns OFF to stop the blower.
Operates completely independently from both the
mode control knob and temperature control knob.
Changes the fan speed in any mode and at any
speed.
Intake Air Control Knob
Operates by electricity.
Switches between recirculating the passenger
compartment air and bringing outside air into the
passenger compartment.
Is normally in fresh air mode.
Illuminates the indicator lamp when in the recalculat
ing mode.
Heater Core
The heater core heats the air before enters the vehicle.
Engine coolant is circulated through the core to heat
the outside air passing over the fins of the core. The
core is functional at all times and may be used to
temper conditioned air in the A/C mode as well as in
the heat or the vent mode.

2. With the ignition ON, allow the engine to warm up
for about 20 minutes. Drive the vehicle at 48 km/h
(30 mph).
3. Use a thermometer to measure the ambient air
temperature and the discharge air temperature at
the heater outlet.
Does the heater output meet the minimum value
given?
1. Check the vehicle for cold air leaks at the following
locations:
Dash.
Heater case.
Vents.
2. Check under the seat for obstructions.
