2004.5 Spectra Technology
Heating, Ventilation, & Air Conditioning (HVAC)
The control module operates the intake (fresh and
recirculation) actuator open or closed. With B+
applied to terminal 2, the motor rotates clockwise
(CW) to close the fresh air inlet duct. With B+ applied
to terminal #1, the motor rotates counter clockwise
(CCW) to open the fresh air inlet duct. A
potentiometer is not used for door location feedback,
the A/C control module senses current flow when the
door stalls, then interrupts current to motor.
