General Procedures
1. WARNINGS:
Use extreme care and observe all safety precautions related to the
use of refrigerants. Due to refrigerant hazards, always wear safety
goggles and non-penetrable gloves when working on or flushing air
conditioning (A/C) systems. Failure to follow this instruction may result
in personal injury.
When flushing the A/C system, refer to the manufacturers
equipment instructions for additional information. Failure to do so may
result in system damage or personal injury.
The A/C refrigerant analyzer must be used before the recovery of
any vehicle's A/C refrigerant. Failure to do so puts shop bulk refrigerant
at risk of contamination. If the vehicle A/C refrigerant is contaminated,
refer the customer to return to the repair facility that performed the last
A/C repair. If the customer wishes to pay the additional cost, use the
A/C recovery equipment that is designated for recovering contaminated
A/C refrigerant. All contaminated A/C refrigerant must be disposed of as
hazardous waste. For additional information, refer to the manufacturers
equipment instructions. Failure to follow this instruction may result in
personal injury.

Climate Control System - General Information - Electronic Leak Detection
General Procedures
1. WARNING: Good ventilation is necessary in the area where A/C leak
testing is to be carried out. If the surrounding air is contaminated with
refrigerant gas, the leak detector will indicate this gas all the time.
Odors from other chemicals such as antifreeze, diesel fuel, disc brake
cleaner, or other cleaning solvents can cause the same problem. A fan,
even in a well ventilated area, is very helpful in removing small traces of
contamination from the air that might affect the leak detector. Failure to
follow this instruction may result in personal injury.
Attach an R-134a manifold gauge set or use a UL-approved
recovery/recycling device such as an R-134a A/C refrigerant center (which
meets SAE Standard J 1991). For additional information, refer to the
manufacturers equipment instructions.
Both gauges should indicate 413-551 kPa (60-80 psi) at 24°C
(75°F) with the engine off.
If little or no pressure is indicated, carry out the air conditioning
(A/C) system recovery, evacuation and charging procedure.
For additional information, refer to Air Conditioning (AC) System Recovery, Evacuation and Charging in this section.
2. Use an R134-a Automatic calibration halogen leak detector to leak test
the refrigerant system. For additional information, refer to the

System Operation
Operation of the heating and ventilation system is controlled by the ATC module. Refer to: Control Components (412-01 Climate Control, Description and Operation).
The system can be operated in automatic or manual mode, with temperature settings selected using the switches on the
integrated control panel.
When the engine is running, coolant is constantly circulated through the heater core by the engine coolant pump and the
auxiliary coolant pump. Where fitted, the auxiliary coolant pump is energized by the CJB on receipt of medium speed CAN bus signals from the ATC module. The CJB broadcasts auxiliary coolant pump status over the medium speed CAN bus for use by other vehicle systems.
The blower is supplied with power by the blower relay on the RJB and connected to ground via the blower control module. The blower control module regulates the voltage across the blower motor to control blower speed. The voltage set by the blower
control module is controlled by a PWM (pulse width modulation) signal from the ATC module. The ATC module uses a feedback signal from the blower control module to monitor blower speed.
Refer to: Control Components (412-01 Climate Control, Description and Operation).
Heater Assembly Component Description
The heater assembly controls the temperature and flow of air supplied to the air distribution ducts. The heater assembly is
mounted on the vehicle centerline, between the instrument panel and the engine bulkhead.
The heater assembly consists of a casing that contains an A/C (air conditioning) evaporator, a heater core, two air distribution
control doors and two temperature blend control doors. On 2.7L diesel vehicles, the heater assembly also contains an electric
booster heater.
Refer to: Electric Booster Heater (412-02 Auxiliary Climate Control, Description and Operation).
Mounted on the heater casing are four stepper motors. Each of the stepper motors is connected to either an air distribution
control door or a temperature blend control door.
The A/C evaporator is part of the A/C system. Refer to: Air Conditioning (412-01 Climate Control, Description and Operation).
The heater core provides the heat source to warm the air supplied to the passenger compartment. The heater core is an
aluminum two pass, fin and tube heat exchanger, and is installed across the width of the heater housing. Two aluminum tubes
attached to the heater core extend through the engine bulkhead and connect to the engine cooling system. For additional
