What are you going to do with the box? Try to get a refund? Throw it away? Sell for scrap? If you are going to keep it, I'd do some trouble shooting. Mark the position of the control valve with punch marks or some method. Pull the control valve off the box to expose the valve actuation lever. Have someone gently move the steering wheel, the lever should move with the slightest movement of the wheel. If it does, I would guess your problem is in the control valve. If it doesn't, or moves only after a lot of wheel movement, I would guess your problem is in the box. I feel your pain.
