Fig. 1
DESCRIPTION The heating-A/C system uses a reversible, 12-volt direct current (DC) servo motor which mechanically positions the recirculation-air door. The recirculation door actuator (1) is located on the side of the HVAC air inlet housing. The recirculation door actuator is interchangeable with the actuators for the blend-air door and the mode-air door. Each actuator is contained within a black molded plastic housing with an integral wire connector receptacle (2) and integral mounting tabs (3) that allow the actuator to be secured to the HVAC housing. The recirculation door actuator output shaft (4) is directly connected to the pivot shaft lever of the recirculation-air door. The recirculation door actuator does not require mechanical indexing to the recirculation-air door, as it is electronically calibrated by the A/C-heater control.

ACTUATOR-BLEND DOOR
The blend 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 HVAC wire harness. The blend door actuator can move the blend- 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 blend-air door will move in one direction. When the A/C-heater control reverses the polarity of the voltage to the motor, the blend-air door moves in the opposite direction. When the A/C-heater control makes the voltage to both connections high or both connections low, the blend-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 blend door actuator and the blend-air door. The A/C-heater control learns the blend-air door stop positions during the actuator calibration procedure and will store a diagnostic trouble code (DTC) for any problems it detects in the blend door actuator circuits (refer to HEATING & AIR CONDITIONING - ELECTRICAL DIAGNOSTICS article for more information).
The blend door actuator cannot be adjusted or repaired and must be replaced if found inoperative or damaged.
