You probably have a faulty temp blend door motor assembly on the front unit. It is located directly behind the radio, way back in on the front of the heater case.
Could also be the door inside behind that assembly is broken. The door lifts to allow hot air and drops to close to send cold air. I am in the process of fixing mine and it aint pretty, but cheaper to get the assembly than to replace the door which requires the whole assembly to be replaced. Lots of luck with it.

Why is your 2000 ford windstar not blowing hot air in the front or the back?
Because there is no heat in either front or back, I would suspect the engine thermostat first. If it never opens, the coolant is essentially prevented from getting to the heater cores. See "Related Questions" below for more
Where is the problem in the heating system when rear heat works but front heat does not?
I would first check either the controls to the front heater core or a blocked front heater core. It could also be a blocked or missing heater hose to the front heater core, although that seems quite unlikley.
