It is hard to figure out what you are saying, but I assume you mean there are two 14/2 or 12/2 cables coming to your existing vent fan. The way it was probably wired before was one of the white wires is the neutral, and the rest of them were all switched hot wires. If you have already taken the wiring loose you are going to have to figure out which cable ...
Not counting the ground wires, you have four insulated conductors. One could be the supply hot, each of the others could be switched hot leads. The presumption would be that the neutral is in the ceiling box and not present in the wall box. Totally possible. If this is true, please mark the switched hot leads appropriately.
One switch originally controlled the light and vent, and the other originally controlled the heater? Or did only one switch control everything? Clearly you don't have three separate switched wires and a neutral and a ground. It's barely possible that the ground was used as a neutral before, and the white was used as a switch leg, but that's a seriously bad ...
Build a box that goes over the whole fan (on the attic side) in the winter-time. weatherstrip the bottom and weight as needed. This is also my preferred approach to the attic stairs that don't seal worth a darn. Duct-board (foil-stiff_fiberglass-foil) is probably the best material if you can find it - use aluminum foil duct tape for the joints. Nobody seems ...
