Check under your hood and see if the vacuum tube has come off the heater control valve. If it will not shut the hot water off it will blow hot. Mine did that.
OP has a 2000, sometime in the early 2000 models Ford OMITTED the vacuum shutoff valve. My 2003 F250 DOES NOT HAVE any hot water shutoff so the core is always hot.
The OP has one of two known issues, the easy one to fix is the A/C compressor clutch, the clutch material has worn down and is not engaging the compressor.. And YES, when the compressor is not engaging you WILL get HOT air..
To fix that you pull the compressor clutch and remove a shim to re-establish the correct air gap for the clutch.
The worst case issue is the "blend" door motor which blends the hot and cool air has failed.. Changing the blend door motor is a real bear from what I understand..
Do a search for a/c compressor clutch repair, should be able to find that info and do a search for Ford blend door motor should be able to find details on that repair..
