Note. To avoid damaging the vehicle or Air Conditioning (A/C) components, the following precautions must be observed. The A/C refrigerant of all vehicles must be identified and analyzed prior to refrigerant charging. Failure to do so can contaminate the shop bulk refrigerant and other vehicles. Do not add R-12 refrigerant to an A/C system that requires the use of R-134a refrigerant. These 2 types of refrigerant must never be mixed. Doing so can damage the A/C system. Charge the A/C system with R-134a refrigerant gas while the engine is running only at the low-pressure side to prevent refrigerant slugging from damaging the A/C compressor. Use only R-134a refrigerant. Due to environmental concerns, when the A/C system is drained, the refrigerant must be collected using refrigerant recovery/recycling equipment. Federal, State/Provincial and/or local laws REQUIRE that R-134a be recovered into appropriate recovery equipment and the process be conducted by qualified technicians who have been certified by an approved organization, such as Automotive Service Excellence (ASE) or Mobile Air Conditioning Society (MACS). Use of a recovery machine dedicated to R-134a is necessary to reduce the possibility of oil and refrigerant incompatibility concerns. Refer to the instructions provided by the equipment manufacturer when removing refrigerant from or charging the A/C system. Refrigerant R-134a must not be mixed with air for leak testing or used with air for any other purpose above atmospheric pressure. R-134a is combustible when mixed with high concentrations of air and higher pressures. A number of manufacturers are producing refrigerant products that are described as direct substitutes for refrigerant R-134a. The use of any unauthorized substitute refrigerant can severely damage the A/C components. If repair is required, use only new or recycled refrigerant R-134a.

Note. To avoid contamination of the Air Conditioning (A/C) system, the following precautions must be observed. Never open or loosen a connection before recovering the refrigerant. When loosening a connection, if any residual pressure is evident, allow it to leak out before opening the fitting. Evacuate a system that has been opened to install a new component or one that has discharged through leakage before charging. Seal open fittings with a cap or plug immediately after disconnecting a component from the system. Clean the outside of the fittings thoroughly before disconnecting a component from the system. Do not remove the sealing caps from a new component until ready to install. Refrigerant oil will absorb moisture from the atmosphere if left uncapped. Do not open an oil container until ready to use and install the cap immediately after using. Store the oil in a clean, moisture-free container. Install a new O-ring seal before connecting an open fitting. Coat the fitting and O-ring seal with PAG oil before connecting. When installing a refrigerant line, avoid sharp bends. Position the line away from the exhaust or any sharp edges that can chafe the line. Tighten threaded fittings only to specifications. The steel and aluminum fittings used in the refrigerant system will not tolerate overtightening. When disconnecting a fitting, use a wrench on both halves of the fitting to prevent twisting of the refrigerant lines or tubes. Do not open a refrigerant system or uncap a new component unless it is as close as possible to room temperature. This will prevent condensation from forming inside a component that is cooler than the surrounding air.

The Electronic Manual Temperature Control (EMTC) system heats or cools the vehicle depending on the HVAC module - control panel selection.

1. The control panel selections determine heating or cooling, air distribution and enables blower motor operation.
2. The temperature control setting determines the air temperature.
3. The blower motor switch varies the blower motor speed.
4. During A/C operation, the system also reduces the relative humidity of the air.

The Dual Automatic Temperature Control (DATC) system maintains the selected vehicle interior temperature by heating and/or cooling the air.

1. During A/C operation, the system also reduces the relative humidity of the air.
2. The driver may override the automatic mode of operation.
3. The temperature control setting determines the air temperature.
4. The blower motor control override buttons vary the blower motor speed.
5. The driver side and passenger side temperature settings can be individually controlled.

The system consists of the following components

1. A/C compressor
2. A/C compressor clutch assembly
3. A/C condenser core
4. A/C evaporator core
5. Receiver/drier
6. Connecting refrigerant lines
7. Thermostatic Expansion Valve (TXV)
8. A/C pressure transducer
9. Heater core and evaporator core housing
10. HVAC module
11. Front Controls Interface Module (FCIM)

Note. An Air Conditioning (A/C) refrigerant analyzer must be used before the recovery of any vehicle's A/C refrigerant. Failure to do so puts the shop's bulk refrigerant at risk of contamination. If the vehicle's A/C refrigerant is contaminated, refer the customer to the service facility that carried out the last A/C service. 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 all equipment, follow the equipment manufacturer's procedures and instructions.

Note. On vehicles being serviced for an internal compressor or desiccant failure, a new suction accumulator or receiver/drier, Thermostatic Expansion Valve (TXV) or evaporator core orifice and any hoses containing mufflers must be installed prior to filtering the Air Conditioning (A/C) system. Internal plumbing of these devices makes it impossible to correctly remove any foreign material. These components are typically discarded after A/C system contamination. Hoses without mufflers can normally be reused unless they are clogged with foreign material. The filter is intended for use on one vehicle only.

1. Orient the filter inlet toward the A/C condenser core.
2. Disconnect the condenser outlet fitting and temporarily install the pancake filter between the 2 halves of the fitting. Use flexible R-134a service hoses of 17,238 kPa (2,500 psi) burst rating. Make the connections using the correct adapters from the A/C Flush Adapter Kit and/or A/C Flush and Purge Fitting Kit.
3. Lubricate the refrigerant system with the correct amount of clean PAG oil. For additional information, refer to «REFRIGERANT OIL ADDING»(ref-439786-S02905206562011120900000) in this service information.
4. Evacuate and charge the refrigerant system. For additional information, refer to «AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING»(ref-439786-S11679771342011120900000) in this service information.
5. Check all refrigerant system hoses, lines and the position of the newly installed filters to be sure they do not interfere with other engine compartment components. If necessary, use tie straps to make adjustments.
6. Provide adequate airflow to the front of the vehicle (with a fan, if necessary). Select A/C operation and set the blower motor speed to maximum. Start the engine and let it idle briefly. Make sure the A/C system is operating correctly.
7. Using a scan tool, command the idle to gradually bring the engine up to 1,200 rpm by running it at lower rpms for short periods (first at 800 rpm, then at 1,000 rpm). Set the engine at 1,200 rpm and run it for one hour with the A/C system operating.
8. Stop the engine.
9. Recover the refrigerant. For additional information, refer to «AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING»(ref-439786-S11679771342011120900000) in this service information.
10. Remove the adapters, flexible hoses and pancake filter from between the condenser and the condenser to evaporator tube.
11. Discard the pancake filter. It can be used one time only.
12. Reconnect the condenser outlet fitting.
13. Evacuate, charge and leak-test the refrigerant system. For additional information, refer to «AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING»(ref-439786-S11679771342011120900000) in this service information.

Note. There are typically 4 types of objectionable odors found in a vehicle: Chemical odors Environmental odors Human and other interior-generated odors Microbiological odors

Before determining that A/C odor treatment is required, the source and the circumstances under which the odor occurs must be determined.

Note. Chemical odors are usually constant regardless of the climate control system setting although they may be enhanced by A/C operation. Most chemical odors are caused by fluid leaks or incorrectly cured adhesives. Chemical odors can be eliminated by repairing the leaking component and removing any residue.

Note. Environmental odors usually occur for a short time and diminish after the vehicle passes through the affected area. These odors are typically only detected when the vehicle windows are open, or when the climate control system is operating in a mode that allows for fresh air. Environmental odors cannot be eliminated because they are external in source, but they may be minimized by switching to a climate control setting that uses recirculated air.

Note. Human and other interior-generated odors occur while the source is present and may linger for a short time after. These odors may be more noticeable during A/C operation. Human odors may be eliminated by removing the source and cleaning the affected area.

Note. Microbiological odors, if in the A/C system, usually last for about 30 seconds after the system is turned on. They will be detected while the A/C is turned on and using either outside or recirculated air. Microbiological odors that occur in areas other than the A/C system (for example, water in doors or wet carpeting) may last indefinitely and will be more intense when recirculated air is used. Microbiological odors will not be present at temperatures at or below 10°C (50°F).

Microbiological odors can be eliminated by removing the source and treating the affected area. Standing water must be allowed to drain and dry out. A/C systems may be treated by using A/C cooling coil coating as described in the service procedure below.

Microbiological odors result from microbial growth supported by warm temperatures and moisture. Microbiological odors are described as musty/mildew type smells and may occur on/in

1. foam seals.
2. rubber seals.
3. adhesives.
4. standing water.
5. water soaked carpet/trim.
