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 article 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	REFER to: Communications Network .
Externally Controlled Variable Displacement Compressor (EVDC) poor performance/does not operate correctly	Refer to Pinpoint Test	GO to Pinpoint Test O
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	GO to Pinpoint Test H
The air inlet door is inoperative or does not operate correctly	Refer to Pinpoint Test	GO to Pinpoint Test D
Incorrect/erratic direction of airflow from outlets	Refer to Pinpoint Test	GO to Pinpoint Test E
Insufficient, erratic or no heat	Refer to Diagnostic Routine	GO to Pinpoint Test F
The Air Conditioning (A/C) is inoperative	Refer to Pinpoint Test	GO to Pinpoint Test G
Insufficient A/C (air conditioning) cooling	Improper refrigerant level Temperature door actuator	CARRY OUT the refrigerant system tests. Refer to the appropriate Refrigerant System Tests procedure. If OK, DIAGNOSE for a temperature door actuator not operating correctly. GO to Pinpoint Test I
The Air Conditioning (A/C) is always on -- Air Conditioning (A/C) mode always commanded ON	Refer to Pinpoint Test	GO to Pinpoint Test H
Temperature control is inoperative or does not operate correctly	Refer to Pinpoint Test	GO to Pinpoint Test I
The blower motor is inoperative	Refer to Pinpoint Test	GO to Pinpoint Test J
The blower motor does not operate correctly	Refer to Pinpoint Test	GO to Pinpoint Test K
The electric booster heater is inoperative or does not operate correctly	Refer to the Pinpoint Test	GO to Pinpoint Test V
Insufficient Heat In Auto Start-Stop Mode Only	Refer to Pinpoint Test	GO to Pinpoint Test P
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. 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.
