Air Door Actuator / Motor: Description and Operation
Mode Door Actuator - Operation
OPERATION
The mode door actuator is connected to the A/C-heater control through the vehicle electrical system by a dedicated two-wire lead and connector of the
instrument panel wire harness. The mode door actuator can move the mode-air door in two directions. When the A/C-heater control pulls the voltage on
one side of the motor connection high and the other connection low, the mode-air door will move in one direction. When the A/C-heater control reverses
the polarity of the voltage to the motor, the mode-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 mode-air door stops and will not move.
The A/C-heater control uses a pulse-count positioning system to monitor the operation and relative position of the mode door actuator and the mode-air
door. The A/C-heater control learns the mode-air door stop positions during the calibration procedure and will store a diagnostic trouble code (DTC) for
any problems it detects in the mode door actuator circuits See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Diagnostic Trouble Code Tests and Associated Procedures.
The mode door actuator cannot be adjusted or repaired and it must be replaced if inoperative or damaged.
