What is your question?
when turning the selector from floor to defrost nothing happens. the fan is blowing but not much air is coming out of the vent. I can change the selector to any position and there is no change in air coming out of the vents

The air flow position selector is controlled by vacuum operated motors. Check to see first if any vacuum hoses under the dash are inadvertently detached. This could be a simple repair. If this is not the case, normal testing of the system should be performed to determine the cause of failure.
