1993 Honda Civic

My civic dx will only blow air out of panel vents not defrost, floor, etc. When the buttons are pushed in the light comes on the selected button but only panel air any advice thanks.

The buttons are electronic and they will light when pushed in, but the different vents of the car depend on other devices to open them. They will vary from small motors to open and close them to a cable that runs them manually with your movement of a knob. Check the cabling and fuses.
