no air comes out of my front vent, but the rear vent work fine. if this is an actuator problem, can you tell me which one it is?
One of the actuators is not working or there is a problem with the blend door.
How doI determine which one it is?
By messing with it, it is moving a stem, lever, for lack of words to move the door it is on. Take them off you have too with the fan blowing move the door.
