1993 Oldsmobile Cutlass Air not blowing

While I was driving, I turned the heater on high and dust/smoke (I couldn't tell which) blew out of the vents. I turned the heater immediately down and shortly after it stopped blowing air all together. Now I can't get any setting to blow any air. I tried changing the fuse, but it just blew the new one immediately and nothing changed. The rest of the car seems to be in working condition. Is there a quick easy fix to this or do I need to take it to a mechanic?
