CORE-HEATER
DESCRIPTION
The heater core (1) is a heat exchanger made of rows
of tubes and fins. The heater core is positioned within
the HVAC housing through the panel (2) located at the
front of the HVAC housing. The heater core tubes (3)
are attached to the front of the heater core and are
secured to the HVAC housing by a bracket.
The heater core can be serviced by removing the
HVAC housing assembly from the vehicle.
OPERATION
Engine coolant is circulated through the heater hoses to the heater core atall times. As the coolant flows through
the heater core, heat is removed from the engine and is transferred to the heater core tubes and fins. Air directed
through the heater core picks up the heat from the heater core fins. The blend-air door(s) allows control of the
heater output air temperature by regulating the amount of air flowing through the heater core. The blower motor
speed controls the volume of air flowing through the HVAC housing.
The heater core cannot be repaired and, if faulty or damaged, it must be replaced.
REMOVAL
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in accidental airbag deploymentand possible personal injury or
death.
NOTE: Disassembly of the HVAC housing is not required to remove heater core.

FAN-A/C CONDENSER
DESCRIPTION
All models equipped with gasoline engines, except
SRT 8, use an electric cooling fan to help pull heat out
of the A/C system, especially during idle conditions.
Without a cooling fan, A/C high side pressures would
increase and A/C system performance would eventu-
ally deteriorate.
The A/C condenser fan consists of a plastic fan blade
assembly which is driven by a 12-volt direct current
(DC) motor (1) with an integral wire harness connector
(2). The A/C condenser fan is mounted within a plastic
shroud (3) behind the A/C condenser (4) located in the
left front of the engine compartment.
OPERATION
The A/C condenser fan used in gasoline engine equipped models (except SRT 8) is controlled by the powertrain
control module (PCM). When the A/C-heater control is set to any A/C position, it sends a request signal on the
CAN-B bus to the totally integrated power module (TIPM), which then transfers the request on the CAN-C Bus to
the PCM/ECM, which sends a signal on a dedicated hard-wired circuit to the totally integrated power module (TIPM)
to energize the internal A/C condenser fan high side driver. When energized, the A/C condenser fan high side driver
provides battery current to the condenser fan motor.
The A/C condenser fan control system isdiagnosed using a scan tool (Refer to 24 - HVAC Electrical Diagnostics for
more information).
The components of the A/C condenser fan cannot be repaired and, if faulty ordamaged, they must be replaced as
an assembly.

LINE-A/C DISCHARGE
DESCRIPTION
The A/C discharge line is the refrigerant line that goes from the A/C compressor to the A/C condenser and has an
integral fitting for the A/C pressure transducer (Refer to 24 - HEATING & AIR CONDITIONING/CONTROLS/TRANS-
DUCER-A/C PRESSURE - DESCRIPTION).
The A/C discharge line for the 5.9L Diesel engine is serviced as an assemblywith the suction line.
The A/C discharge line for the 8.3L engine is secured to the top of fan shroudby two retainers.
CAUTION: Use only O-ring seals specified for the vehicle. Failure to use correct O-ring seal will cause the
refrigerant system connection to leak.
The A/C discharge line has no serviceable parts except the rubber O-ring seals. The O-ring seals used on the
connections are made from a special type of rubber not affected by R-134a refrigerant. The O-ring seals must be
replaced whenever the A/C discharge line is removed and installed.
If the A/C discharge line is found to be leaking or is damaged, it must be replaced.
