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.

Action
Verify the customer’s complaint.
Are the customer’s concerns verified?
Check the coolant level.
Is the coolant level correct?
Add coolant as needed
Is the repair complete?
Check the serpentine accessory drive belt for tension
or damage.
Is the ’serpentine accessory drive belt OK?
Correct any problem with serpentine accessory drive
belt.
Is the repair complete?
Check the coolant hoses for leaks or kinks.
Are the coolant hoses OK?
Repair any problem with the coolant hoses.
Is the repair complete?
Check the coolant reservoir cap. Refer to Section 1D,
Engine Cooling.
Is the coolant reservoir cap OK?
Repair or replace the coolant reservoir cap as needed.
Is the repair complete?
1. Set the A/C switch OFF on the vehicles equipped
with air conditioning.
2. Set the temperature control lever to full hot.
3. Set the blower motor switch on 4.
4. Turn the ignition ON.
5. Check for the airflow from the vent outlet.
Is there a heavy airflow from the vent outlet?
Check for change in the airflow at various blower
speeds.
Does the blower speed increase as the switch is turned
from 1 to 4?
1. With the engine sufficiently cool, remove the
coolant reservoir cap.
2. Set the blower motor switch on 4.
3. Set the temperature control lever to full hot.
4. Start the engine and idle the engine.
5. Watch for the flow of the coolant.
Is the coolant flow visible?Yes

CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when
a tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this
cable will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK
unless other-wise noted.

DIAGNOSIS USING THE MANIFOLD GAUGE
On normal operation during the cooling cycle, the
manifold gauge must indicate approximately 1.5 - 2.0
kg/cm
2 at low pressure side and 14.5 - 15 kg/cm2 at
high pressure side, on condition that the temperature
at the cooler inlet, 30 ºC - 35 ºC, 2,000 rpm of the
engine rpm , full cold and maximum blower speed.
Cause Symptom
Action
1. High and low pressure are abnormally low.
2. Air at cooler outlet is not cold.
1. High and low pressure are abnormally high.
1. High and low pressure are abnormally high.
2. Connection at the low pressure is not cold.
There is a gas leak in the
cooling system.
Insufficient cooling and
faulty condenser cooling
by excessive
refrigerant.
Belt is slipped
There is an air in the
cooling system
Check the oil leak,
repair

condenser
Repair the belt
Clean and repair the
receiver-drier
Check the oil
contamination etc.
