trouble code (DTC) for any problems it detects in the rear blend door actuator circuits.
The rear blend door actuator is diagnosed using a scan tool See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Diagnostic Trouble Code Tests and Associated Procedures.
The rear blend door actuator cannot be adjusted or repaired and must be replaced if inoperative or damaged.
Front
DESCRIPTION
The mode door actuator (1) for the front heating-A/C system is a reversible, 12 volt direct current (DC) servo motor, which is connected directly to the
linkage for the mode-air doors. The mode door actuator is located on the passenger side of the front HVAC air distribution housing.
The mode door actuator is contained within a black molded plastic housing with an integral wire connector receptacle (2), an output shaft with splines
(3) that connect it to the mode door linkage and three integral mounting tabs (4) that allow the actuator to be secured to the air distribution housing. The
mode door actuator does not require mechanical indexing to the mode door linkage, as it is electronically calibrated by the A/C-heater control.
The A/C-heater control must be recalibrated each time an actuator motor is replaced See: Testing and Inspection/Component Tests and General
Diagnostics/HVAC System Test.
The mode door actuator is interchangeable with the actuators for the blend-air door(s) and the recirculation-air door.
