Symptom Chart: Climate Control - Electronic Manual Temperature Control (EMTC)

Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic 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	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
HVAC functions are inoperative/do not operate correctly from touchscreen only	Communication network APIM	REFER to: Information and Entertainment System .
Reduced outlet airflow	Plugged cabin air filter	INSPECT the cabin air filter. REFER to: Cabin Air Filter . If OK, DIAGNOSE for low refrigerant charge, A/C always commanded on or blower motor not operating correctly.
	Improper refrigerant level	CARRY OUT the refrigerant system tests. REFER to: Refrigerant System Tests - 2.3L EcoBoost (201kW/273PS) . REFER to: Refrigerant System Tests - 3.5L Duratec (209kW/284PS) . REFER to: Refrigerant System Tests - 3.5L EcoBoost (257kW/350PS) . REFER to: Refrigerant System Tests - 3.7L Duratec (227kW/301PS) . If refrigerant charge is OK, GO to Pinpoint Test H
	Blower motor	GO to Pinpoint Test K
The air inlet door is inoperative	Refer to Pinpoint Test	GO to Pinpoint Test D
Incorrect or erratic direction of airflow from outlets	Refer to Pinpoint Test	GO to Pinpoint Test E
Insufficient, erratic or no heat	Refer to Pinpoint Test	GO to Pinpoint Test F
The A/C is inoperative	Refer to Pinpoint Test	GO to Pinpoint Test G
The A/C is always on -- A/C mode always commanded ON	Refer to Pinpoint Test	GO to Pinpoint Test H
Temperature control is inoperative/does not operate correctly -- driver side	Refer to Pinpoint Test	GO to Pinpoint Test I
The front blower motor is inoperative	Refer to Pinpoint Test	GO to Pinpoint Test J
The front blower motor does not operate correctly	Refer to Pinpoint Test	GO to Pinpoint Test K
The rear blower motor is inoperative	Refer to the Pinpoint Test	GO to Pinpoint Test Q
The rear blower motor does not operate correctly	Refer to the Pinpoint Test	GO to Pinpoint Test R
Insufficient A/C cooling	Improper refrigerant level	CARRY OUT the refrigerant system tests. REFER to: Refrigerant System Tests - 2.3L EcoBoost (201kW/273PS) . REFER to: Refrigerant System Tests - 3.5L Duratec (209kW/284PS) . REFER to: Refrigerant System Tests - 3.5L EcoBoost (257kW/350PS) . REFER to: Refrigerant System Tests - 3.7L Duratec (227kW/301PS) . If OK, DIAGNOSE for a temperature door actuator not operating correctly.
Insufficient A/C cooling	Temperature door actuator	GO to Pinpoint Test I
A/C pressure relief valve discharging	A/C pressure relief valve	CHECK the high side system pressure. If the pressure is below the A/C pressure relief valve open pressure (500-600 psi), INSTALL a new A/C Compressor. REFER to: Air Conditioning (A/C) Compressor - 2.3L EcoBoost (201kW/273PS) . REFER to: Air Conditioning (A/C) Compressor - 3.5L Duratec (209kW/284PS) . REFER to: Air Conditioning (A/C) Compressor - 3.5L EcoBoost (257kW/350PS) . REFER to: Air Conditioning (A/C) Compressor - 3.7L Duratec (227kW/301PS) .
A/C pressure relief valve discharging	High system pressure	CHECK the high side system pressure. If the system pressure is above the A/C pressure relief valve open pressure (500-600 psi), REPAIR the A/C system for a restriction.
Climate control does not operate only when remote start is used	IPC information display settings Non-Ford approved remote start system installed	VERIFY Remote Start - Message Center Set To Auto, or Remote Start - Message Center Set To Last User Settings. REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - System Operation And Component Description . VERIFY module communications network operation. DIAGNOSE Diagnostic Trouble Codes (DTCs) if present.
