Default Fan direction dial

My fan will only blow in the floor and windshield no matter what the control is set on. However it will turn off. Any thoughts?

Sounds like the actuator. that's a little servo motor inside the dash that controls the internal air flow. had one go out in my buick a while back.

This started after the turbo install right?
The actuators rely on engine vacuum to operate properly, you need to plug the vacuum hose into a vacuum source since the intake now gets boost (pressure) instead of vacuum.
