(Fig. 1)
(5) Separate and remove a/c lines from vehicle.
INSTALLATION
(1) Before installation, replace all O-rings and gas-
kets. Coat all sealing surfaces with approved wax-
free refrigerant oil. Then, reverse the above
procedures.
(2) Evacuate and recharge system.
REAR HEATER A/C AIR OUTLETS
REMOVAL
Separate barrel from bezel by pulling outward.
INSTALLATION
For installation, push the outlet firmly into the
opening until it locks into place.
REAR HEATER-A/C AUXILIARY CONDENSER
If vehicle is equipped with a 3.3L or 3.8L engine
with rear heater and air conditioning, it will be
equipped with an auxiliary condenser. The auxiliarycondenser is mounted on the primary condenser in
front of the radiator. Both condenser must be
removed as an assembly and then separated.
WARNING: THE REFRIGERATION SYSTEM MUST
BE COMPLETELY EMPTY BEFORE PROCEEDING
WITH THIS OPERATION.
NOTE: Special effort must be used to keep all
R-134a system components moisture-free. Moisture
in the oil is very difficult to remove and will cause a
reliability problem with the compressor.
The condenser assembly must first be removed
from vehicle. Refer to CONDENSER ASSEMBLY
removal and installation in this section for service
procedures.
REMOVAL
(1) After condenser assembly removal, place on
bench for disassembly.
(2) Remove (1) bolt to liquid line on auxiliary con-
denser.
(3) Remove (4) attaching bolts and separate auxil-
iary from primary condenser. (Fig. 15)
INSTALLATION
(1) Before installation, replace all O-rings and gas-
kets. Coat all sealing surfaces with approved wax-
free refrigerant oil. Then, reverse the above
procedures.
(2) Evacuate and recharge system.

capacity of the system and consequently result in
higher discharge air temperatures.
NOTE: The oil used in the Denso 2.5L Turbo Diesel
and the Denso 2.0L gasoline engine compressors is
ND-8 PAG R134a refrigerant oil. Only refrigerant oil
of the same type should be used to service the sys-
tem. Do not use any other oil. The oil container
should be kept tightly capped until it is ready for
use. Tightly cap afterwards to prevent contamina-
tion from dirt and moisture. Refrigerant oil will
quickly absorb any moisture it comes in contact
with. Special effort must be used to keep all R-134a
system components moisture-free. Moisture in the
oil is very difficult to remove and will cause a reli-
ability problem with the compressor.
It will not be necessary to check oil level in the
compressor or to add oil unless there has been an oil
loss. Oil loss at a leak point will be evident by the
presence of a wet, shiny surface around the leak.
REFRIGERANT OIL LEVEL CHECK
When an air conditioning system is first assem-
bled, all components (except the compressor) are
refrigerant oil free. After the system has been
charged with R134a refrigerant and operated, the oil
in the compressor is dispersed through the lines and
components. The evaporator, condenser, and filter-
drier will retain a significant amount of oil, refer to
the Refrigerant Oil Capacities chart. When a compo-
nent is replaced, the specified amount of refrigerant
oil must be added. When the compressor is replaced,
the amount of oil that is retained in the rest of the
system must be drained from the replacement com-
pressor. When a line or component has ruptured and
oil has escaped, the compressor should be removed
and drained. The compressor is drained through the
suction port or by removing the sump bolt on top of
the compressor, refer to Compressor Removal and
Installation procedures. The filter-drier must be
replaced along with the ruptured part. The oil capac-
ity of the system, minus the amount of oil still in the
remaining components, can be measured and poured
into the suction port of the compressor.
Example: The evaporator retains 50 ml (1.7 oz.).
The condenser retains 30 ml (1 oz) of oil, and system
capacity may be 220 ml (7.40 oz) of oil.
220 ml minus 90 ml = 130 ml (4.40 oz.).
CAUTION: The refrigerant oil used in a R-134a A/C
system is unique. Use only oils which were designed
to work with R-134a refrigerant. The oil designated
for the Denso 2.5L Turbo Diesel and Denso 2.0L gas-
oline engine compressors is ND-8 PAG compressor
oil. For gasoline vehicles still using R-12 refrigerant,
use ND8 PAG compressor oil.
SERVICING REFRIGERANT OIL LEVEL
(1) Using a refrigerant recovery machine, remove
refrigerant from the A/C system.
(2) Remove refrigerant lines from A/C compressor.
(3) Remove compressor from vehicle.
(4) From suction port on top of compressor, drain
refrigerant oil from compressor.
(5) Add system capacity minus the capacity of
components that have not been replaced through suc-
tion port on compressor. Refer to the Refrigerant Oil
Capacity Chart.
(6) Install compressor, connect refrigerant lines,
evacuate, and charge refrigerant system.
DIAGNOSIS AND TESTING
ACTUATOR CALIBRATION/DIAGNOSTICS AND
COOLDOWN TEST
GENERAL INFORMATION
If the HVAC control module is replaced, the Cali-
bration Diagnostic and Cooldown tests will need to
be performed. Once this group of tests have success-
fully passed, they can be performed individually. The
engine must be running during the test to provide
hot coolant for the heater, A/C compressor operation
and to assure that the actuators are calibrated cor-
rectly. The HVAC control module is capable of trou-
bleshooting the system in approximately 120 seconds.
If a condition is detected, an error code is displayed.
The error code cannot be erased until the condition is
repaired and the diagnostic test is performed. Check
wire before replacing components, refer to Group 8W,
Wiring Diagrams.
CAUTION: Do not remove the actuators from the
Heater-A/C unit assembly with power applied.
Removal should only be done with the Ignition OFF.
The actuators have no mechanical stops to limit the
travel. If the actuator rotates and is not connected to
the unit assembly, it will become out of calibration.

tion compensates for mechanical variations in the
