Has Your Actuator Failed?
Failures of the actuators often lead to the air door becoming stuck in one position, leading to improper ventilation.
Electrical Failures: Motor Failure, Poor Electrical Connections, or Internal Electrical Components on the PCB Fail
Mechanical Failures: Broken Gears (Split in the Main Driver Gear or Broken Teeth on Small Gears)
Functional Failures: Internal Feedback for the Actuator's Position no Longer Functions Properly, often Resulting in an Intermittent Failure.
Which Actuator Do You Need?
RECIRCULATION
Controls the intake of air into the system, either bringing outside air in or using inside air in recirculation.
BLEND
Controls the temperature of the air flowing from the vents by mixing hot and cold air from the heater core and the evaporator core.
MODE
Controls which vents have air flow, i.e. Floor, Panel or Front, Defrost, or any combination of those.
Diagram:
Main vs. Auxiliary
The term "Main" refers to the air flow control of the Front Vents. The term "Auxiliary" refers to the air flow control of the Rear Vents.
Many actuators that control the air flow to the rear vents are still located in the front of the vehicle. Some larger and/or higher end vehicles may have Auxiliary air door actuators in the center console or in the rear of the vehicle.
