WARNING: This page is about a different car, the 1999 Lincoln Navigator and 1999 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The A/C electronic blend door actuator is located on rear of A/C evaporator housing assembly. It controls A/C temperature blend door movement on command from the EATC module. Internally, an electronic circuit accepts commands from EATC selection and positions A/C temperature blend door using a reversible electric motor. An integral potentiometer feeds temperature blend door position information to EATC module.
