Why is my electric furnace not blowing out hot air?

I would guess the heating elements are not all working properly, if at all. So, could be burned out elements, bad sequencers, or,, well, to tell the truth, way to many things to explain here. I suggest having a pro into look at it. Or you can give us detailed description of where you have power and where you don't. On second thought, don't do that, as its not worth getting electricuted over... Just call in a pro.
