If your 2005 Nissan Titan's AC is blowing through the defrost vents but not the dash vents, it may indicate a problem with the mode door actuator. This component controls the airflow direction, and if it's malfunctioning or stuck, it can prevent air from reaching the dash vents. Another possibility is a vacuum leak in the system, which can affect the operation of blend doors. Checking for any diagnostic trouble codes or inspecting the actuator for proper function would be a good next step.
