How do you replace the heater hoses on the firewall of a Ford Taurus - Mercury Sable that come from the heater core?

In a nutshell, very carefully. Remove the clamps and split the hoses with a knife where the hose is on the outlet tubes. Take some spray lubricant and spray some on the connections while you force a screwdriver around the hose. That will keep you from damaging the outlet tubes. I hope you are not replacing the heater core as it is a very large chore.
This isn't going to be easy unless you have the smaller size 'Vulcan" engine - in which case you might actually be able to get your hands down behind the engine.
Couple of thoughts:
- If getting to the hoses from the top side of the engine is not easy, consider trying coming from the bottom. That may provide better access angles to the hose ends
- There is a tool for dealing with those factory clamps you might also want to look into
- This might also be a good time to flush the heater core since the hoses are going to be disconnected.
- If you ARE replacing the heater core, be sure to read through ALL of the linked questions - especially those that talk about a way to replace the core WITHOUT removing the dash!

If its just the cord, then follow the old cord to the back side of the engine ( really the side of the engine closest to the firewall ) and replace it. When the engine is cold, plug it in and you will hear the block heater heating up. If you don't hear anything, then replace the heater also. That requires a little more knowledge.

The AC has to be dischared, and the AC lines have to be removed at the firewall. The AC drier has to be remved, because there are nuts on the outside of the firewall under the hood to remove that are hidden by the drier. I believe there are 4 nuts to remove, but there might only be three.
