Is the blower running at all? Also, make sure the main air intake vent is free of obstructions.
Also, a vacuum leak could cause the actuator to not function correctly. I'd check into the vacuum lines if all else fails. I've had too many cars here with heat/air problems due to vacuum loss and the actuators not switching correctly.
