heater no air coming out

Would the control on dash cause there to be no air coming out heater vents on floor. I can hear the blower very loudly in dash about in the middle air comes out dash vents and out defroster ducts. When you switch to heater you get blower noise but very little air coming out floor vents.is it the control or possibly a vacuum mother on a vent somewhere

There is probably a directional door under the dash that is having a problem for some reason.

Is this vehicle a 98?
