Symptom Chart - Climate Control Systems
WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.
Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. For information about these practices, REFER to: Diagnostic Methods .
| Condition | Possible Sources | Actions |
|---|---|---|
| A module does not communicate with the diagnostic scan tool | Fuse(s) Wiring, terminals or connectors module |
|
| Externally Controlled Variable Displacement Compressor (EVDC) poor performance/does not operate correctly | Refer to Pinpoint Test | GO to Pinpoint Test X |
| Unable to duplicate the customer concern and no Diagnostic Trouble Codes (DTCs) present | Refer to Pinpoint Test | GO to Pinpoint Test C |
| Reduced outlet airflow | Plugged or wet cabin air filter Frozen evaporator |
Inspect the cabin air filter. REFER to: Cabin Air Filter . GO to Pinpoint Test I |
| The air inlet door is inoperative or does not operate correctly | Refer to Pinpoint Test | If equipped with air inlet door actuator with 2 circuits, GO to Pinpoint Test D If equipped with air inlet door actuator with 5 circuits, GO to Pinpoint Test E |
| Incorrect/erratic direction of airflow from outlets | Refer to Pinpoint Test | GO to Pinpoint Test F |
| Insufficient, erratic or no heat | Refer to Diagnostic Routine | GO to Pinpoint Test G |
| The Air Conditioning (A/C) is inoperative | Refer to Pinpoint Test | GO to Pinpoint Test H |
| Insufficient A/C (air conditioning) cooling | Improper refrigerant level Temperature door actuator |
CARRY OUT the refrigerant system tests. Refer to Refrigerant System Tests - 1.0L EcoBoost (92kW 125PS) or Refrigerant System Tests - 2.0L Duratec-HE (129kW 175PS) If OK, DIAGNOSE for a temperature door actuator not operating correctly. GO to Pinpoint Test J |
| The Air Conditioning (A/C) is always on -- Air Conditioning (A/C) mode always commanded ON | Refer to Pinpoint Test | GO to Pinpoint Test I |
| Temperature control is inoperative or does not operate correctly | Refer to Pinpoint Test | GO to Pinpoint Test J |
| The blower motor is inoperative | Refer to Pinpoint Test | GO to Pinpoint Test K |
| The blower motor does not operate correctly | Refer to Pinpoint Test | GO to Pinpoint Test L |
| Insufficient Heat In Auto Start-Stop Mode Only | Refer to Pinpoint Test | GO to Pinpoint Test Z |
| Air Conditioning (A/C) pressure relief valve discharging | A/C pressure relief valve High system pressure |
Using a manifold gauge set, CHECK the A/C system pressure. If the pressure is below the A/C pressure relief valve open pressure, 3, 447-4, 137 kPa (500-600 psi), INSTALL a new A/C Compressor. Refer to the appropriate A/C Compressor - Removal and Installation procedure in REMOVAL AND INSTALLATION If the A/C system pressure is above the A/C pressure relief valve open pressure 3, 447-4, 137 kPa (500-600 psi), REPAIR the A/C system for a restriction. |
| The Electric Booster Heater Is Inoperative Or Does Not Operate Correctly | Refer to Pinpoint Test | GO to Pinpoint Test AB |
