2002 Chevrolet Trailblazer Q&A
2002 Chevrolet Trailblazer Question: ac mode knob
There are little motors(actuators) inside the dashboard that operate doors that direct the airflow and temperature in the cabin. One of these actuators or flaps is not working properly, or the system that controls the actuators is having a problem. You will need to dig into the dash to see if these actuators are operating, and see that the control module is working properly. - TurboSDCharger
