7B–2 MANUAL CONTROL HEATING, VENTILATION, AND AIR CONDITIONING SYSTEM
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
SYSTEM COMPONENTS
–FUNCTIONAL
Compressor
All compressors are belt–driven from the engine crank-
shaft through the compressor clutch pulley. The com-
pressor pulley rotates without driving the compressor
shaft until on electromagnetic clutch coils energized.
When voltage is applied to energize the clutch coil, the
clutch plate and hub assembly are drawn toward the
pulley. The magnetic force locks the clutch plate and
pulley together as one unit to drive the compressor
shaft.
Condenser Core
The condenser assembly in front of the radiator consists
of coils which carry the refrigerant and cooling fins that
provide the rapid transfer of heat. The air passing
through the condenser cools the high–pressure refriger-
ant vapor and cause it to condense into a liquid.
Expansion Valve
The expansion valve is located on the passenger
compartment side of the dash panel. The expansion
valve can fail in three different positions: open, closed,
or restricted. An expansion valve that fails in the open
position will result in a noisy A/C compressor or no cool-
ing. The cause can be a broken spring, a broken ball, or
excessive moisture in the A/C system. If the spring or
the ball is found to be detective, replace the expansion
valve. If excessive moisture is found in the A/C system,
recycle the refrigerant. An expansion valve that fails in
the closed position will result in low suction pressure and
no cooling. This may be caused by a failed power done
or excessive moisture in the A/C system. If the power
dome on the expansion valve is found to be defective,
replace the expansion valve. If excessive moisture is
found in the A/C system, recycle the refrigerant.
A restricted expansion valve will result in low suction
pressure and no cooling. This may be caused by debrisin the refrigerant system. If debris is believed to be
cause, recycle the refrigerant, replace the expansion
valve, and replace the receiver/dryer.
Evaporator Core
The evaporator is device which cools and dehumidifies
the air before it enters the vehicle. High–pressure liquid
refrigerant flows through the expansion tube (orifice)
and becomes a low–pressure gas in the evaporator. The
heat in the air passing through the evaporator core is
transferred to the cooler surface of the core, which cools
the air. As the process of heat transfer from the air to the
evaporator core surface is taking place, any moisture
(humidity) in the air condenses on the outside surface of
the evaporator core and is drained off as water.
Receiver–Dryer
The sealed receiver–dryer assembly is connected to the
evaporator outlet pipe. It acts as a refrigerant storing
container, receiving liquid and some vapor and refriger-
ant oil from the evaporator.
At the bottom the receiver–dryer is the desiccant, which
acts as a drying agent for the moisture that may have
entered the system. The receiver–dryer is serviceable
only as an assembly.
Dual Cut Switch
The dual cut switch controls compressor operation when
the cycling refrigerant pressure is dropped or surged.
Evaporator Thermistor
A semiconductor which resistance is noticeably changed
as the change of temperature. When the refrigerant tem-
perature of the evaporator drops to 0C (32F) and be-
low, the evaporator cores get stuck with frost or ice,
reducing the airflow, lowering the cooling capacity. The
thermistor is a sensor which is used to prevent from frost-
ing or icing.
The thermistor is installed on the evaporator.

REPAIR INSTRUCTIONS
ON-VEHICLE SERVICE
GENERAL A/C SYSTEM
SERVICE PROCEDURES
O-RING REPLACEMENT
Important: Even though O-rings may look identical, it is
extremely important that only recommended service re-
placement air conditioning O-rings be used, or exces-
sive leakage of refrigerant may occur.
Important: Always slip the O-ring onto the flange tube
to ensure proper locating and sealing.
Install new DAEWOO-approved service replacement air
conditioning O-rings whenever a joint or a fitting is disas-
sembled, except when the O-rings are provided on new
components.
When replacing O-rings on an air conditioning compo-
nent or a joint connection, the fitting design should be
identified to ensure installation of the correct air condi-
tioning service replacement O-ring.
Before installation, verify that both O-rings and fittings
have not been nicked or deformed. Deformed or nicked
parts must be replaced. Failure to use the proper service
replacement parts and procedures may result in exces-
sive refrigerant leakage.
HANDLING REFRIGERANT
Caution: Always work in a well-ventilated area and
avoid breathing any refrigerant fumes. If you have
difficulty breathing, seek medical attention immedi-
ately. If refrigerant comes in contact with any part of
your body, flush the exposed area with water. If a
rash or pain develops, seek medical attention.
Air conditioning systems contain refrigerant. This is a
chemical mixture which requires special handling proce-
dures to avoid personal injury.
Always wear goggles and wrap a clean cloth around the
fittings, the valves and the connections when performing
work that involves opening the refrigerant system. Do
not weld or steam clean on or near any vehicle-installed
air conditioning lines or components.
All refrigerant drums are shipped with a heavy metal
screw cap. The purpose of the cap is to protect the valve
and the safety plug from damage. It is good practice to
replace the cap after each use of the drum.
If it is necessary to transport or carry any container of
refrigerant in a vehicle, do not carry it in the passenger
compartment.
HANDLING OF REFRIGERANT LINES
AND FITTINGS
Notice: Using too low or too high torque when tightening
a fitting can result in loose joints or deformed joint parts.
Both conditions can result in refrigerant leakage.
Keep all metal tubing lines free of dents or kinks. Any
line restrictions will cause the loss of system capacity.
Never bend a flexible hose line to a radius of less than
four times the diameter of the hose.
Never allow a flexible hose line to come near the ex-
haust manifold.
Inspect flexible hose lines regularly for leaks or brittle-
ness.
Replace flexible hose lines with new lines if you find
signs of deterioration or leaking.
Discharge the refrigeration system of all refrigerant
before disconnecting any fitting in the refrigeration
system.
Proceed very cautiously regardless of the gauge
readings.
Open the fittings very slowly.
Keep your face and your hands away from the fitting
so that you will not be injured if there happens to be
liquid refrigerant in the line.
If you notice pressure when you loosen a fitting, allow
the pressure to bleed off as described under “Dis-
charging, Adding Oil, Evacuating and Charging Pro-
cedures for A/C System” in this section.
Cap or tape any refrigerant line immediately after it is
opened. This will prevent the entrance of moisture
and dirt, which can cause internal compressor wear
or plugged lines in the condenser, the evaporator
core, the expansion valve or the compressor inlet
screens.
Important: Use two proper wrenches to connect the O-
ring fittings.
Back up the opposing fitting to prevent distortion of
the connecting lines or the components.
Back up both the swaged fitting on the flexible hose
connections and the coupling to which it is attached
with two wrenches to prevent turning the fitting and
damaging the ground seat.
Keep the O-rings and the seats in perfect condition. A
burr or a piece of dirt may cause a refrigerant leak.
Dip new O-rings in clean PAG refrigerant oil before
installation.
