Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. For information about these practices,
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).

Network Diagnostic Trouble Codes (DTCs) (U-codes) are often a result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures, such as module reprogramming, often set network Diagnostic Trouble Codes (DTCs). Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery.
REFER to: Battery (414-01 Battery, Mounting and Cables, Diagnosis and Testing).

The Air Inlet Blend Door Is Inoperative


Refer to Wiring Diagrams Cell 55 for schematic and connector information.

Normal Operation and Fault Conditions

To rotate the air inlet blend door actuator, the FCIM supplies voltage and ground to the air inlet blend door actuator through the door actuator motor circuits. To reverse the air inlet blend door actuator rotation, the FCIM reverses the voltage and ground circuits. The air inlet blend door actuator feedback resistors are supplied a ground from the FCIM by the air inlet blend door actuator return circuits and a 5-volt reference voltage on the air inlet blend door actuator reference circuits. The FCIM reads the voltage on the air inlet blend door actuator feedback circuits to determine the air inlet blend door actuator position by the position of the actuator feedback resistor wiper arm.

During an actuator calibration cycle, the FCIM drives the air inlet blend door until the door reaches both internal stops in the FCIM case. If the air inlet mode door is temporarily obstructed or binding during a calibration cycle, the FCIM may interpret this as the actual end of travel for the door. When this condition occurs and the FCIM commands the actuator to its end of travel, the air intake may not be from the expected source.

Refrigerant System Tests Diagnostic Table

  1. NOTE: The following table is used to guide diagnosis of the refrigerant system if operating pressures are outside normal limits.

    NOTE: Variable compressors operate at lower pressures and are dependent on correct system charge for normal operation.

    Refer to the chart below.



High (Discharge) Pressure Low (Suction) Pressure Component — Causes
High Normal to High
  • Condenser — inadequate airflow.
  • Engine — overheating.
Normal to High Normal
  • Refrigerant overcharge — air in refrigerant.
Normal to Low High
  • A/C Compressor — low performance.
    • Before condemning the A/C compressor verify the refrigerant system has the correct system charge.
Normal to Low Normal to High
  • A/C suction line — partially restricted or plugged. a
Normal to Low Low
  • Low refrigerant charge — leak in system.
  • A/C suction line — partially restricted or plugged. b
Erratic Operation or Compressor Not Running
  • Ambient Air Temperature (AAT) sensor — poor connection.
  • A/C pressure transducer — poor connection.
  • Evaporator temperature sensor — poor connection.
  • Low refrigerant charge — leak in system.
Additional Possible Components or Causes Associated With Inadequate Compressor Operation
  • Compressor Drive Belt — loose
  • Compressor Clutch — slipping
  • Clutch Coil Open — shorted, or loose mounting
  • Control Assembly Switch — dirty contacts or sticking open
  • Clutch Wiring Circuit — high resistance, open or blown fuse
  • Compressor Operation Interrupted by Engine Computer
Additional Possible Components or Causes Associated With a Damaged Compressor
  • Incorrect Clutch Air-gap
  • Suction Accumulator — refrigerant oil bleed hose plugged
  • Refrigerant Leaks

a Low pressure reading is normal to high if restriction is downstream of service access valve.

b Low pressure reading is low if restriction is upstream of service access valve.


Component Test- Heater Core

NOTE: If a heater core leak is suspected, test the heater core by following the plugged heater core component test before the heater core pressure test. Carry out a system inspection by checking the heater system thoroughly as follows:

  1. Inspect for evidence of coolant leakage at the heater hose to heater core attachments. A coolant leak in the heater hose could follow the heater core tube to the heater core and appear as a leak in the heater core.

NOTE: Spring-type clamps are installed as original equipment. Installation and overtightening of non-specified clamps can cause leakage at the heater hose connection and damage the heater core.

  1. Check the integrity of the heater hose clamps.

Heater Core - Plugged

  1. Check to see the engine coolant is at the correct level.
  1. Start the engine and turn on the heater.
  1. When the engine coolant reaches operating temperature, check the heater core inlet and outlet hoses to see if they are hot.
  1. If the outlet only is not hot:
  1. If the inlet only is not hot, the thermostat may not be working correctly.

Heater Core - Pressure Test

NOTE: Due to space limitations, a bench test may be necessary for pressure testing.

  1. Drain the coolant from the cooling system.
  1. Disconnect the heater hoses from the heater core.
  1. Install a short piece of heater hose, approximately 101 mm (4 in) long on each heater core tube.
  1. Fill the heater core and heater hoses with water and install the plug BT-7422-B and the adapter BT-7422-A from the Pressure Test Kit. Secure the heater hoses, plug and adapter with hose clamps.
  1. Attach the pump and gauge assembly from the Pressure Test Kit to the adapter.
  1. Close the bleed valve at the base of the gauge. Pump 138 kPa (20 psi) of air pressure into the heater core.
  1. Observe the pressure gauge for a minimum of 3 minutes.
  1. If the pressure drops, check the heater hose connections to the core tubes for leaks. If the heater hoses do not leak, remove the heater core from the vehicle and carry out the bench test.

Heater Core - Bench Test

  1. Remove the heater core from the vehicle.
  1. Drain all of the coolant from the heater core.
  1. Connect the 101 mm (4 in) test heater hoses with plug and adapter to the core tubes. Then connect the Pressure Test Kit to the adapter.
  1. Apply 138 kPa (20 psi) of air pressure to the heater core. Submerge the heater core in water.
  1. If a leak is observed, install a new heater core.

Component Test- Evaporator or Condenser Core On-Vehicle Leak Test

  1. Discharge and recover the refrigerant.
  1. Disconnect the suspect evaporator core or condenser core from the A/C system.
  1. Clean the manifold fittings.
  1. Connect the appropriate test fittings from the A/C Flush Adapter Kit to the condenser or evaporator core tube connections.

NOTE: The automatic shut-off valves on some gauge set hoses do not open when connected to the test fittings. If available, use hoses without shut-off valves. If hoses with shut-off valves are used, make sure the valve opens when attached to the test fittings or install an adapter that will activate the valve. The test is not valid if the shut-off valve does not open.

  1. Connect the red and blue hoses from the R-134a Manifold Gauge Set to the test fittings on the evaporator core or condenser core. Connect the yellow hose to a known good vacuum pump.
  1. Open both gauge set valves and start the vacuum pump. Allow the vacuum pump to operate for a minimum of 45 minutes after the gauge set low pressure gauge indicates 101 kPa (30 in-Hg). The 45-minute evacuation is necessary to remove any refrigerant from oil left in the evaporator core or condenser core. If the refrigerant is not completely removed from the oil, outgassing will degrade the vacuum and appear as a refrigerant leak.
  1. If the low pressure gauge reading will not drop to 101 kPa (30 in-Hg) when the valves on the gauge and manifold set are open and the vacuum pump is operating, close the gauge set valves and observe the low pressure gauge. If the pressure rises rapidly to zero, a large leak is indicated. Recheck the test fitting connections and gauge set connections before installing a new evaporator core or condenser core.
  1. After evacuating for 45 minutes, close the gauge set valves and stop the vacuum pump. Observe the low pressure gauge; it should remain at the 101 kPa (30 in-Hg) mark.
  1. If the evaporator core or condenser core does leak, as verified by the above procedure, install a new evaporator core or condenser core.

Component Test- Air Conditioning (A/C) Compressor External Leak Test

  1. Install the appropriate adapter from the A/C Flush Adapter Kit on the port of the A/C Compressor, using the existing manifold retaining bolt.
