Short Description: Diagnosing Ford’s Electronic Blend Door Actuator For Manual Air Conditioning Many of Ford’s manual air conditioning systems use an electronic blend door actuator (motor) to control the temperature of the air entering the passenger compartment.
Content Inside: Many of Ford’s manual air conditioning systems use an electronic blend door actuator (motor) to control the temperature of the air entering the passenger compartment. The temperature knob on the A/C–Heater control panel is a variable resister (potentiometer) which varies a voltage signal to the motor. This signal determines blend door movement. Complaints of temperature always hot, cold or not changing as the temperature knob is rotated will be caused by one of four problems: 1) bad actuator; 2) bad potentiometer; 3) open or shorted wire(s); 4) broken door
