The blend door actuators (1) for the front heating-A/C system are reversible, 12-volt direct current (DC) servo motors. Models with the front single zone heating-A/C system have a single blend-air door, which is controlled by a single blend door actuator. Models with the front dual zone heating-A/C system have dual blend-air doors, which are controlled by two blend door actuators.
The blend door actuator for the single zone heating-A/Csystem is located on the driver side front HVAC air distribution housing. For the dual zone heating-A/C system, the same blend door actuator used for the single zone system becomes the driver side blend door actuator, which is mechanically connected to only the driver side blend-air door. A second separate blend door actuator is also located on the passenger side of the front air distribution housing which is mechanically connected to only the passenger side blend-air door.
The blend door actuators are contained within a black molded plastic housing with an integral wire connector receptacle (2). An output shaft with splines (3) connect the blend door actuators to the blend door linkage. Three integral mounting tabs (4) allow the actuators to be secured to the air distribution housing. The blend door actuators do not require mechanical indexing to the blend door linkage, as they are electronically calibrated by the A/C-heater control.
The A/C-heater control must be recalibrated each time an actuator motor is replaced. Refer to DTC-Based Diagnostics/HVAC - Standard Procedure .
The blend door actuators are interchangeable with the actuators for the recirculation and mode-air doors.

The A/C expansion valve controls the amount of refrigerant entering the A/C evaporator. The A/C expansion valve is of a thermostatic expansion valve (TXV) design and consists of an aluminum H-valve type body (1) with an inlet port (2), outlet port (3) and an integral thermal sensor (4).
The A/C expansion valve is located in the engine compartment at the dash panel, between the A/C refrigerant lines and the A/C evaporator.
