1. A/C compressor
2. A/C clutch
3. A/C condenser core
4. A/C evaporator core
5. A/C charge port valve (high side)
6. A/C charge port valve (low side)
7. connecting refrigerant line
8. function selector switch
9. suction accumulator

The refrigerant system operation is controlled by the following

1. A/C evaporator core orifice
2. A/C cycling switch
3. A/C compressor pressure relief valve
4. A/C pressure cut-off switch
5. A/C clutch relay
6. Powertrain control module (PCM)

The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch.

The A/C cycling switch senses A/C evaporator core pressure to control A/C compressor operation.

An A/C compressor pressure relief valve is installed in the A/C manifold and tube assembly (3.0L (4V) engine), on the discharge port of the A/C compressor (2.3L engine) to protect the refrigerant system against excessively high refrigerant pressures.

An A/C evaporator core orifice is installed in the condenser-to-evaporator line to meter the liquid and vapor mixture refrigerant into the A/C evaporator core.

A/C Compressor Pressure Relief Valve

An A/C compressor pressure relief valve is incorporated in the compressor A/C manifold and tube to

1. relieve unusually high refrigerant system discharge pressure buildups of 3,792 kPa (550 psi) and above.
2. prevent damage to the A/C compressor and other system components.
3. avoid total refrigerant loss by closing after the excessive pressure is relieved.

Condenser Core

Note. Installation of a new suction accumulator is not necessary when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

The condenser core has the following characteristics

1. It is an aluminum fin-and-tube design heat exchanger located in front of the vehicle radiator.
2. It cools compressed refrigerant gas by allowing air to pass over the fins and tubes to extract heat and by condensing gas to liquid refrigerant as it is cooled.

Refrigerant Lines

Note. Installation of a new suction accumulator is not necessary when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

The condenser to evaporator line contains high-pressure liquid refrigerant upstream of the evaporator core orifice. The A/C manifold and tube assembly is attached to the compressor with O-ring seals.

Evaporator Core

Note. Installation of a new suction accumulator is not necessary when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C component or damage to the suction accumulator.

The evaporator housing contains the evaporator core. The evaporator core is the plate/fin type with a unique refrigerant flow path.

1. A mixture of refrigerant and oil enters the bottom of the evaporator core through the evaporator core inlet tube and is routed so it flows through the partitioned first 4 plate/fin sections.
2. The next 4 plate/fin sections are partitioned to force the refrigerant to flow toward the other end of the evaporator core.
3. The next 5 plate/fin sections are partitioned to force the refrigerant to flow toward the bottom of the evaporator core.
4. Refrigerant then continues through to the remaining 5 plate/fin sections and then moves out of the evaporator core through the evaporator core outlet tube.
5. This W-pass flow pattern transfers the flow of refrigerant and oil through the evaporator core.

Evaporator Core Orifice Tube

Note. Install a new evaporator core orifice whenever a new A/C compressor is installed.

The evaporator core orifice has the following characteristics

1. color-coded orange
2. an orifice diameter of 1.46 mm (0.0575 inch)
3. located in the condenser to evaporator line
4. changes the high-pressure liquid refrigerant into a low-pressure liquid
5. filter screens located on the inlet and outlet ends of the orifice body
6. the inlet filter screen acts as a strainer for the liquid refrigerant flowing through the A/C evaporator core orifice
7. O-ring seals on the evaporator core orifice prevent the high-pressure liquid refrigerant from bypassing the evaporator core orifice
8. adjustment or repair cannot be made to the evaporator core orifice (a new evaporator core orifice must be installed)

Suction Accumulator

Note. Installation of a new suction accumulator is not necessary when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

The suction accumulator is mounted to the A/C accumulator bracket. The inlet tube of the suction accumulator is connected to the evaporator outlet tube. The outlet tube is connected to the A/C manifold and tube assembly.

After entering the inlet of the suction accumulator, heavier oil-laden refrigerant contacts an internally mounted dome (which serves as an umbrella) and drips down onto the bottom of the canister.

1. A small-diameter oil bleed hole, in the bottom of the vapor return tube, allows the accumulated heavier liquid refrigerant and oil mixture to re-enter the compressor suction line at a controlled rate.
2. As the heavier mixture passes through the small diameter liquid bleed hole, it has a second chance to vaporize and recirculate through the A/C compressor without causing compressor damage due to slugging.
3. A fine mesh screened filter fits tightly around the bottom of the vapor return tube to filter out refrigerant system contaminant particles.
4. A desiccant bag is mounted inside the canister to absorb any moisture which may be in the refrigerant system.
5. A fitting located on the top of the suction accumulator is used to attach the A/C cycling switch. A long-travel Schrader-type valve stem core is installed in the fitting so that the A/C cycling switch can be removed without discharging the A/C system.

A/C Cycling Switch

The A/C cycling switch is mounted on a Schrader valve-type fitting on the top of the suction accumulator.

1. A valve depressor, located inside the threaded end of the A/C cycling switch, presses in on the Schrader valve stem.
2. This allows the suction pressure inside the suction accumulator to control the operation of the A/C cycling switch.
3. The electrical switch contacts open when the suction pressure drops to 145-165 kPa (21-24 psi).
4. The contacts close when the suction pressure rises to 200-317 kPa (29-46 psi).
5. When the A/C cycling switch contacts close, the signal to energize the A/C clutch is sent to the powertrain control module (PCM) which energizes the A/C relay and supplies B+ voltage to the A/C clutch field coil.
6. When the A/C cycling switch contacts open, the A/C clutch field coil is de-energized and compressor operation stops.
7. The A/C cycling switch controls the A/C evaporator core pressure at a point where the plate/fin surface temperature is maintained slightly above freezing.
8. This prevents icing of the A/C evaporator core and blockage of airflow.
9. It is not necessary to discharge the refrigerant system to remove the A/C cycling switch.

High Pressure Cut-off Switch

The high pressure cut-off switch is used to interrupt A/C compressor operation in the event of high system discharge pressures.

1. The high pressure cut-off switch is mounted on a Schrader valve-type fitting on the high pressure side of the condenser to evaporator line.
2. A valve depressor, located inside the threaded end of the high pressure cut-off switch, is used to monitor the compressor discharge pressure.
3. It is not necessary to discharge the refrigerant system to remove the A/C pressure cut-off switch.
4. The high pressure cut-off switch has 2 sets of contacts. One electrical contact is normally closed.
5. When the compressor discharge pressure rises to approximately 3,103 kPa (450 psi), the switch contacts open, disengaging the A/C compressor.
6. When the pressure drops to approximately 1,724 kPa (250 psi), the contacts close to allow operation of the A/C compressor. The switch contains a second set of electrical contacts used for high-speed fan control.
7. When the compressor discharge pressure reaches approximately 2,241 kPa (325 psi), these contacts close and engage the high-speed fan control.
8. When the pressure drops to approximately 1,896 kPa (275 psi), the contacts again open and the high speed fan control is disengaged.

Scheme 25

The spring lock coupling is a refrigerant line coupling held together by a garter spring inside a circular cage.

1. When the coupling is connected together, the flared end of the female fitting slips behind the garter spring inside the cage of the male fitting.
2. The garter spring and cage then prevent the flared end of the female fitting from pulling out of the cage.
3. The O-ring seals are green in color and are made of a special material.
4. Use only the specified green O-ring seals listed in the Master Parts Catalog for the spring lock coupling.
5. A plastic indicator ring is used on the spring lock couplings of the A/C evaporator core to indicate, during vehicle assembly, that the coupling is connected. Once the coupling is connected, the indicator ring is no longer necessary but remains captive by the coupling near the cage opening.
6. An A/C tube lock coupling clip may be used to secure the coupling but is not necessary.

A/C Line (Peanut) Fitting

The A/C line (peanut) fitting is an integral part of the refrigeration line or component.

Scheme 26

1. The male and female blocks of the air conditioning line (peanut) fitting are retained with a nut.
2. An O-ring seal is installed around the tube on the male block.
3. The female and male blocks are welded to the tubes and are not adjustable.
4. When correctly assembled the male and female fittings should be flush.

Air Conditioning - Escape Hybrid

The auxiliary evaporator housing contains an auxiliary battery zone air filter. This is to reduce the amount of airborne particulates entering the battery compartment. The filter is located inside the auxiliary evaporator housing and should be serviced every year or 15,000 miles (24000 km). For additional information, refer to the Owner Guide Manual. To remove the air filter, remove the LH rear quarter trim access panel, the air filter is located behind the auxiliary evaporator housing access door.

The A/C refrigerant system is a clutch cycling orifice-type tube. The system consists of the following components

1. A/C compressor
2. A/C clutch
3. A/C condenser core
4. A/C evaporator core
5. A/C compressor pressure relief valve
6. Auxiliary evaporator core
7. Auxiliary thermostatic expansion valve
8. Underbody refrigerant lines
9. A/C charge port valve (high side)
10. A/C charge port valve (low side)
11. connecting refrigerant lines
12. suction accumulator

The refrigerant system operation is controlled by the following

1. Front evaporator thermistor
2. Auxiliary evaporative thermistor
3. Passenger zone valve
4. Battery zone valve
5. TBCM
6. Function selector switch
7. A/C evaporator core orifice
8. A/C cycling (low charge protection) switch
9. High pressure cut-off switch
10. PCM
11. Dual function pressure switch (DFPS)

The refrigerant system incorporates an A/C compressor controlled by the PCM.

In addition, the A/C low charge protection switch senses A/C evaporator core pressure to protect the A/C compressor due to a low refrigerant charge.

The dual function pressure switch (DFPS) is used to interrupt the A/C compressor operation in the event of high system discharge pressures. The DFPS is mounted on a schrader-type valve fitting on the compressor manifold and tube assembly. It is not necessary to recover the refrigerant when removing the switch. A valve depressor, located in the threaded end of the DFPS, presses on the schrader-type valve stem allowing the DFPS to monitor the A/C compressor discharge pressure. When the compressor discharge pressure rises, the switch contacts open allowing the PCM to disable the A/C compressor operation. When the compressor discharge pressure drops, the switch contacts close, allowing the PCM to enable the A/C compressor operation.

The DFPS has a second set of electrical contacts used for high-speed cooling fan control. When the A/C compressor discharge pressure rises, the contacts close and send a signal to the PCM requesting high-speed cooling fan operation. When the pressure drops, the contacts open and the signal for high speed engine cooling fan operation is removed.

An A/C evaporator core orifice is installed in the condenser to evaporator line to meter the liquid refrigerant into the A/C evaporator core.

The PCM uses input from the TBCM, the function selector switch and the front evaporator thermistor to determine the position of the passenger zone valve and the operation of the A/C compressor.

If cabin A/C is activated and the TBCM does not require cooling, the PCM sends a high speed controller area network (HS-CAN) message to the TBCM commanding the battery zone valve closed. The PCM will open the passenger zone valve and start the engine in order to run the A/C compressor. The A/C system then operates similar to a standard vehicle, unless the PCM receives a signal from the front evaporator thermistor indicating an impending freezing condition. At that time, the PCM will disengage the A/C compressor clutch until the upper temperature threshold is reached within the front evaporator housing, at which time normal A/C operation will begin again.

If high-voltage battery cooling is active and cabin A/C is activated, the PCM opens the passenger zone valve and runs the engine continuously in order to operate the A/C compressor at full duty. The A/C system then operates similar to a standard vehicle, unless the PCM receives a signal from the front evaporator thermistor or the battery compartment thermistor indicating an impending freezing condition. When the front evaporator begins to freeze, the PCM will close the passenger zone valve until the temperature reaches the upper threshold. During this time, the A/C compressor will continue to run as long as the TBCM requests cooling and the battery compartment thermistor does not indicate an impending freezing condition. Normal cabin A/C operation will resume once the front evaporator reaches the upper temperature threshold.

When the cabin A/C is off, it is normal for the A/C compressor to run when high-voltage battery cooling is necessary. During this time, the passenger zone valve is closed and the gasoline engine may operate on demand or continuously based on these conditions.

An A/C compressor pressure relief valve is incorporated in the compressor A/C manifold and tube to

1. relieve unusually high refrigerant system discharge pressure buildups of 3,792 kPa (550 psi) and above.
2. prevent damage to the A/C compressor and other system components.
3. avoid total refrigerant loss by closing after the excessive pressure has been relieved.

Note. Installation of a new suction accumulator is not necessary when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.

The condenser to evaporator line contains high-pressure liquid refrigerant upstream of the evaporator core orifice. The A/C manifold and tube assembly is attached to the compressor with O-ring seals.

There is also an additional set of lines that carry refrigerant to the rear evaporator for high-voltage battery cooling. These lines are spliced into the front lines in the engine compartment and the liquid line contains a filter.

Note. Installation of a new suction accumulator is not necessary when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C component or damage to the suction accumulator.

There are two evaporator cores on the vehicle: one in the front evaporator housing and one in the auxiliary evaporator housing. The evaporator core is the plate/fin type with a unique refrigerant flow path.

1. A mixture of refrigerant and oil enters the bottom of the evaporator core through the evaporator core inlet tube and is routed so it flows through the partitioned first four plate/fin sections.

There are a total of 2 evaporators on the vehicle: one for cabin cooling, and one for high-voltage battery cooling.

Front Evaporator Core Orifice Tube

Note. Install a new evaporator core orifice whenever a new A/C compressor is installed.

Note. Adjustment or repair cannot be made to the evaporator core orifice. A new evaporator core orifice must be installed.

The front evaporator core orifice has the following characteristics

1. color-coded orange
2. an orifice diameter of 1.44 mm (0.057 inch)
3. located in the condenser to evaporator line
4. changes the high-pressure liquid refrigerant into a low-pressure liquid
5. filter screens located on the inlet and outlet ends of the orifice body the inlet filter screen acts as a strainer for the liquid refrigerant flowing through the A/C evaporator core orifice
6. O-ring seals on the evaporator core orifice prevent the high-pressure liquid refrigerant from bypassing the evaporator core orifice

Air Conditioning (A/C) Low Charge Protection Switch

The A/C low charge protection switch is mounted on a Schrader-type valve fitting on the top of the suction accumulator.

1. A valve depressor, located inside the threaded end of the A/C low charge protection switch presses in on the schrader-type valve stem.
2. This allows the suction pressure inside the suction accumulator to control the operation of the A/C low charge protection switch.
3. The electrical switch contacts open when the suction pressure drops to 80-90 kPa (11-13 psi).
4. The contacts close when the suction pressure rises to 276 max kPa (40 psi max).
5. While the A/C low charge protection switch is closed, voltage is sent to the PCM signaling normal pressure in the A/C system, and the PCM continues to control operation of the A/C compressor based on other inputs.
6. When the A/C low charge protection switch contacts open, voltage is removed to the PCM and the A/C compressor is disengaged.
7. It is not necessary to discharge the refrigerant system to remove the A/C low charge protection switch.

The high pressure cut-off switch, also referred to as the dual function pressure switch, is used to interrupt A/C compressor operation and/or the electric engine cooling fan in the event of high system discharge pressures.

1. The high pressure cut-off switch is mounted on a Schrader-type valve fitting on the high pressure side of the condenser to evaporator line.
2. A valve depressor, located inside the threaded end of the dual function pressure switch, is used to monitor the compressor discharge pressure.
3. It is not necessary to discharge the refrigerant system to remove the dual function pressure switch.
4. The high pressure cut-off switch has 2 sets of contacts. One electrical contact is normally closed.
5. When the compressor discharge pressure rises to approximately 3,000-3,275 kPa (435-475 psi), the switch contacts open, signaling the PCM to disengage the A/C compressor.
6. When the pressure drops to approximately 1,517-1,931 kPa (220-280 psi), the contacts close to allow operation of the A/C compressor. The switch contains a second set of electrical contacts used for high-speed fan control.
7. When the compressor discharge pressure reaches approximately 2,137-2,344 kPa (310-340 psi), these contacts close and send a signal to the PCM to engage the high-speed fan control.
8. When the pressure drops to approximately 1,655-2,137 kPa (240-310 psi), the contacts again open and the high speed fan control is disengaged.
