INSTALLATION
HVAC HOUSING ASSEMBLY
NOTE: The HVAC housing must be removedfrom the vehicle and disassembled for service of the A/C evap-
orator, evaporator temperature sensor, mode-air and blend-air doors.

WARNING: The engine cooling system is designed to develop internal pressures up to 145 kilopascals (21
pounds per square inch). Do not remove or loosen the coolant pressure cap, cylinder block drain plugs,
radiator drain, radiator hoses, heater hoses, or hose clamps while the engine cooling system is hot and
under pressure. Allow the vehicle to cool for a minimum of 15 minutes beforeopening the cooling system
for service. Failure to observe this warning can result in serious burns from the heated engine coolant.
CAUTION
CAUTION: Never add R-12 to a refrigerant system designed to use R-134a. Do not use R-12 equipment or
parts on an R-134a A/C system. These refrigerants are not compatible and damage to the A/C system will
result.
CAUTION: Never use R-12 refrigerant oil in a A/C system designed to use R-134a refrigerant oil. These
refrigerant oils are not compatible and damage to the A/C system will result.
CAUTION: The use of A/C system sealers may result in damage to A/C refrigerant recovery/evacuation/re-
charging equipment and/or A/C system. Many federal, state/provincial and local regulations prohibit the
recharge of A/C systems with known leaks. DaimlerChrysler recommends thedetection of A/C system leaks
through the use of approved leak detectors and fluorescent leak detectiondyes. Vehicles found with A/C
system sealers should be treated as contaminated and replacement of the entire A/C refrigerant system is
recommended. A/C systems found to be contaminated with A/C system sealers, A/C stop-leak products or
seal conditioners voids the warranty for the A/C system.
CAUTION: Recover the refrigerant before opening any fitting or connection. Open the fittings with caution,
even after the system has been discharged. Never open or loosen a connection before recovering the refrig-
erant.
CAUTION: If equipped, do not remove the secondary retention clip from any spring-lock coupler connection
while the refrigerant system is under pressure. Recover the refrigerant before removing the secondary
retention clip. Open the fittings with caution, even after the system has been discharged. Never open or
loosen a connection before recovering the refrigerant.
CAUTION: The internal parts of the A/C system will remain stable as long as moisture-free refrigerant and
refrigerant oil is used. Abnormal amounts of dirt, moisture or air can upset the chemical stability. This may
cause operational troubles or even serious damage if present in more than very small quantities. Before
disconnecting a component, clean the outside of the fittings thoroughly to prevent contamination from
entering the refrigerant system. Keep service tools and the work area clean. Do not open the refrigerant
system or uncap a replacement component until you are ready to service the system. Immediately after
disconnecting a component from the refrigerant system, seal the open fittings with a cap or plug. This will
prevent contamination from entering the A/C system.
CAUTION: Refrigerant oil will absorb moisture from the atmosphere if leftuncapped. Do not open a con-
tainer of refrigerant oil until you are ready to use it. Replace the cap on the oil container immediately after
using. Store refrigerant oil only in a clean, airtight, and moisture-freecontainer.
CAUTION: Do not overcharge the refrigerant system. Overcharging will cause excessive compressor head
pressure and can cause compressor noise and A/C system failure.

ACCUMULATOR-A/C
DESCRIPTION
The A/C accumulator (5) is mounted in the engine
compartment between the evaporator outlet tube (2)
and the A/C suction line (6). An integral mounting
bracket (4) is used to secure the accumulator to the
dash panel (3). The A/C low side service port (1) is
mountedtothetopoftheA/Caccumulator.
CAUTION: Use only O-ring seals specified for the
vehicle. Failure to use the correct O-ring seal will
cause the refrigerant system connections to leak.
The A/C accumulator has no serviceable parts except
for the rubber O-ring seals, low side service port
valve, cap and secondary retaining clips. The O-ring
seals used on the connections are made from a spe-
cial type of rubber not affected by R-134a refrigerant.
The O-ring seals must be replaced whenever the A/C
accumulator is removed and installed.
The A/C accumulator cannot be repaired and, if faulty
or damaged, it must be replaced.
OPERATION
Refrigerant enters the A/C accumulator (1) mostly as a
low pressure vapor through the inlet tube (2). Any liq-
uid, oil-laden refrigerant falls to the bottom of the can-
ister, which acts as a separator. A desiccant bag (3) is
mounted inside the accumulator canister to absorb
any moisture which may have entered and become
trapped within the refrigerant system. A filter (4) is also
mounted inside the canister to trap any foreign mate-
rial that may have entered the refrigerant system dur-
ing assembly. The low pressure vapor exits the A/C
accumulator through the outlet tube (5). On this
model, the low side service port (6) is located at the
top of the A/C accumulator.
The A/C accumulator cannot be repaired. If the A/C
accumulator is faulty or damaged, or if the A/C com-
pressor has failed, it must be replaced.
REMOVAL
WARNING: Review the warnings and cautions in the front of this section before performing the following
operation (Refer to 24 - HEATING & AIR CONDITIONING/PLUMBING - WARNINGS) and (Refer to 24 - HEAT-
ING & AIR CONDITIONING/PLUMBING - CAUTIONS).

CONDENSER-A/C
DESCRIPTION
The A/C condenser is located in the front of the engine compartment behind the grille. The A/C condenser is a heat
exchanger that allows the high-pressure refrigerant gas being dischargedbytheA/Ccompressortogiveupitsheat
to the air passing over the condenser fins, which causes the refrigerant tocool and change to a liquid state.
OPERATION
When air passes through the fins of the A/C condenser, the high-pressure refrigerant gas within the A/C condenser
gives up its heat. The refrigerant then condenses as it leaves the A/C condenser and becomes a high-pressure
liquid. The volume of air flowing over the condenser fins is critical to theproper cooling performance of the A/C
system. Therefore, it is important that there are no objects placed in front of the radiator grille openings at the front
of the vehicle or foreign material on the condenser fins that might obstruct proper air flow. Also, any factory-installed
air seals or shrouds must be properly reinstalled following radiator or A/C condenser service.
The A/C condenser cannot be repaired and, if faulty or damaged, it must be replaced.
