How is the actuator attached to the recirculation door?
How is the actuator attached to the recirculation door?
The recirculation door actuator is contained within a black molded plastic housing with an integral wire connector receptacle (2), an output shaft with splines (3) connect it to the recirculation door and three integral mounting tabs (4) allow the actuator to be secured to the air inlet housing.
How does the a / C heater door actuator work?
The A/C-heater control learns the recirculation-air door stop positions during the calibration procedure and will store a diagnostic trouble code (DTC) for any problems it detects in the recirculation door actuator circuits. The recirculation door actuator cannot be adjusted or repaired and it must be replaced if inoperative or damaged.
When does the recirculation-air door stop moving?
When the A/C-heater control reverses the polarity of the voltage to the motor, the recirculation-air door moves in the opposite direction. Once the A/C-heater control makes the voltage to both connections high or both connections low, the recirculation-air door stops and will not move.
What does the mode door actuator do?
Mode Actuator. The mode actuator is an electronic stepper motor with feedback potentiometers. The HVAC control module sends signals to the mode door actuator through the mode door control circuit. Zero volts drives the actuator in one direction while 5-volts moves the actuator in the opposite direction.
What is an AC door actuator?
An AC actuator is a type of mechanical switch or control arm that is activated by alternating current (AC). Actuators are common components of many mechanical systems. The uses for an AC actuator can include incorporation into automotive controls, gate and door closure mechanisms in residential or commercial settings,…
Where is the heater door actuator located?
The heater and a/c blend door actuator motor is located behind the center of the dash just below the windshield. The steering column must be detached and lowered and the dash must be removed to access the blend door motor. You can’t post conmments that contain an email address.
Were is the air door actuator located?
The A/C electronic blend door actuator is located on top of the A/C evaporator core housing (19A553) assembly. Its function is to move the A/C air temperature control door on command from the control assembly. The A/C electronic blend door actuator contains a reversible electric motor and a potentiometer.
