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

WARNING: This page is about a different car, the 2015 Ford F-150. 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. REFER to: Diagnostic Methods .

Symptom Chart

Condition	Possible Sources	Actions

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 - 2.7L EcoBoost (238kW/324PS) . REFER to: Refrigerant System Tests - 3.5L EcoBoost (272kW/370PS) . REFER to: Refrigerant System Tests - 3.5L Duratec (209kW/284PS) . REFER to: Refrigerant System Tests - 5.0L 32V Ti-VCT . If refrigerant charge is OK, GO to PINPOINT TEST H : THE A/C (AIR CONDITIONING) IS ALWAYS ON - A/C (AIR CONDITIONING) MODE ALWAYS COMMANDED ON
	Blower motor	GO to PINPOINT TEST K : THE BLOWER MOTOR DOES NOT OPERATE CORRECTLY
The air inlet door is inoperative	Refer to Pinpoint Test	GO to PINPOINT TEST D : THE AIR INLET DOOR IS INOPERATIVE
Incorrect or erratic direction of airflow from outlets	Refer to Pinpoint Test	GO to PINPOINT TEST E : INCORRECT OR ERRATIC DIRECTION OF AIRFLOW FROM OUTLETS
Insufficient, erratic or no heat	Refer to Pinpoint Test	GO to PINPOINT TEST F : INSUFFICIENT, ERRATIC OR NO HEAT
Insufficient heat in Auto Start-Stop mode only	Refer to Pinpoint Test	GO to PINPOINT TEST O : INSUFFICIENT HEAT IN AUTO START-STOP MODE ONLY
The A/C is inoperative	Refer to Pinpoint Test	GO to PINPOINT TEST G : THE A/C (AIR CONDITIONING) IS INOPERATIVE
The A/C is always on - A/C mode always commanded ON	Refer to Pinpoint Test	GO to PINPOINT TEST H : THE A/C (AIR CONDITIONING) IS ALWAYS ON - A/C (AIR CONDITIONING) MODE ALWAYS COMMANDED ON
Temperature control is inoperative/does not operate correctly	Refer to Pinpoint Test	GO to PINPOINT TEST I : THE TEMPERATURE CONTROL IS INOPERATIVE OR DOES NOT OPERATE CORRECTLY
The blower motor is inoperative	Refer to Pinpoint Test	GO to PINPOINT TEST J : THE BLOWER MOTOR IS INOPERATIVE
The blower motor does not operate correctly	Refer to Pinpoint Test	GO to PINPOINT TEST K : THE BLOWER MOTOR DOES NOT OPERATE CORRECTLY
Insufficient A/C cooling	Improper refrigerant level	CARRY OUT the refrigerant system tests. REFER to: Refrigerant System Tests - 2.7L EcoBoost (238kW/324PS) . REFER to: Refrigerant System Tests - 3.5L EcoBoost (272kW/370PS) . REFER to: Refrigerant System Tests - 3.5L Duratec (209kW/284PS) . REFER to: Refrigerant System Tests - 5.0L 32V Ti-VCT . If OK, DIAGNOSE for a temperature door actuator not operating correctly.
Insufficient A/C cooling	Temperature door actuator	GO to PINPOINT TEST I : THE TEMPERATURE CONTROL IS INOPERATIVE OR DOES NOT OPERATE CORRECTLY
A/C pressure relief valve discharging	A/C pressure relief valve	CHECK the high side system pressure. REFER to: Specifications . If the pressure is below the A/C pressure relief valve open pressure, INSTALL a new A/C Compressor. REFER to: Air Conditioning (A/C) Compressor - 2.7L EcoBoost (238kW/324PS) . REFER to: Air Conditioning (A/C) Compressor - 3.5L EcoBoost (272kW/370PS) . REFER to: Air Conditioning (A/C) Compressor - 3.5L Duratec (209kW/284PS) . REFER to: Air Conditioning (A/C) Compressor - 5.0L 32V Ti-VCT .
A/C pressure relief valve discharging	High system pressure	CHECK the high side system pressure. REFER to: Specifications . If the system pressure is above the A/C pressure relief valve open pressure, 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.
