Way down low, in the very middle of the firewall.
I just replaced one of mine - the metal portion of the driverside hose assembly had corroded.
You will have easy access if you have the "Vulcan" v6 engine. If you have the DOHC, plan on removing things to clear the way to get your hands down there.

possibly clogged heater core, remove heater core hoses and flush with a hose until clean. reinstall hoses fill with coolant and let it run. if heater core is too plugged up you will have to replace it.
See "Related Questions" below for ideas on fixing Taurus/Sable no-heat problemsAnswerMake sure you have vacuum going in the cab from the engine. The vacuum line runs from the intake to the reservoir, which is a round plastic ball looking thing, and into the cab.AnswerFeel the 2 heater hoses coming from the firewall - since the coolant runs through the heater core all the time, BOTH of the hoses should be hot.If one is not, that's a key indicator the core is plugged/obstructed.
it is located on the passenger side wheel well...it has 4 hoses attached 2 going into the heater core and 2 going into the engine...simply disconnect the hoses and replace with new heater valve
5.0 hours..... 5.5 hours with a center console. Add 1.0 hour for heater hoses... This is for a 2004 model...
Cut off the crimp connectors, pull the old hose off and replace with conventional heater hose and conventional hose clamps
I have a 94 Astro but the heater control valve should be in the same location. Look under the hood on the passenger side. There are two heater hoses behind the coolant reservoir and windshield washer reservoir. The hoses attach to the heater control valve. The valve has a round vacuum actuator on the side, and two more heater hoses leave the control valve and go into the heater core housing. Cost for the valve will probably be somewhere between $50 & $70 To replace it, remove the coolant reservoir and the windshield washer reservoir. Remember, or mark, the hoses for the washer if you have a rear washer. The electrical connections only go on one way. Remove the clamps securing the front heater hoses and remove the hoses from the valve. Remove the clamps holding the heater hoses coming off the back of the valve where they are attached to the heater core. These two hoses are factory attached to the valve and the new valve (from the dealer) comes with the hoses attached to the rear of the valve. The clamps are back in a small space behind the valve, rather hard to get to. We pulled the bracket with the three square relays situated above the hoses to allow easier access. Install in reverse order. Good luck.
Disconnect both heater hoses from engine side, fabricate a fitting to attach a garden hose to one of the hoses coming from the heater, direct the other hose into a container, slowly turn on the water and flush until it runs clear, then reverse hoses and flush again until clear, reconnect hoses to engine and refill reservoir.
Remove the hoses going to the heater core. Use a regular water hose with a high pressure nozzle and flush both ways.
Sounds like a heater hose got left loose or maybe one of the hoses are leaking a little.
AnswerThere is no hoses on an evaporator coil.Assuming your asking about the hoses on either side- You would need to evacuate the system before even trying. So unless you have the equipment like a recovery machine and cylinder, don't even try...AnswerThe process of replacing the heater core in this generation of Taurus / Sables includes having to disconnect the AC lines.See "Related Questions" below for more
hese hoses are called "heater hoses" they are from the front heater hoses which heat the car and they are connected to the front heater hoses under the car hood on right side
need a view of the heater core lines and why somebody did the work wrong on the the heater hoses cant see down inside the engine to fix the issue
