I am getting cool air when the heater is turned on. Where is the thermostat located so I can replace it ? It could be another issue causing the cool air but I highly suspect the thermostat. Please explain in details!
Anmar. It won't be the thermostat...Sable and Taurus have a design problem. The heater core hose going into heater core from water pump gets plugged up right at the heater core bypass junction. At Hardware store..Buy hard plastic hose/tubing about 4ft long that just fits inside of the heater core hose. My ACE hardware has white hard tubing. Cut one end of the hard tubing at angle to use it as a reamer inside the heater core hose. Now place the hard tubing on top of heater hose to measure the distance on hard tubing it has to travel up to firewall . Mark with black marker on hard tubing. Remove the heater core hose from top of water pump and slide hard tubing in hose all the way up to where the bypass connection is feeling the obstruction...rotating the hard tubing as you gently shove it thru heater core hose. Slide it back and forth and keep rotating it until you feel it go past the Bypass junction...10 min at least. Now take off the heater hose from engine on driver side that comes from the heater exit side...Use garden hose high pressure and back flush the crud out. Re connect hoses, add fluid to reservoir as needed. Or take to shop and have them do this. Many shops just back flush...Have them do BOTH! Buy the plastic tubing ahead of time so they have no excuse. I have been doing this on my 98 Taurus since 1999. Done many of these...If you haven't changed thermostat for 4 years ...Change that as well. You tube has videos. Email me at [email protected] I promise you hot air...from the car!
You sould like you know what you are doing, could you please link me to a You Tube video? I'm noob at this and I find it hard to follow, video would be appricated. Thank you!
Sable and Tuyrus pretty much same...

It could be a ''stuck open'' thermostat, but not likely. To prove it to yourself, feel the temperature of the upper and lower radiator hoses. If they feel like the same temperature (or just plain ''hot''), then the problem is not likely the thermostat. It is much more likely to be the temperature controller (in the dashboard). If you have an ''auto'' controlled temperature system (such as ''set it at 75 degrees and it keeps the car at 75 degrees), then the problem is _definitely_ that controller. If you merely have a ''cold to hot'' knob, then the system is much simpler, but BOTH types of systems use a similar ''mixing controller'' and they are known to be a problem in Fords (Mercury is a Ford product, just like Chevy and Buick are a GM product). The controller costs about $50 bucks at RockAuto.com, but you absolutely need to know the exact model you currently have (the same cars can have different part numbered controllers). If the location of the controller (''mixer'') is anything like the location of my Ford Explorer's controller... then you might wanna just let the Dealer do the job. (Or a good local mechanic who can honestly say he has done this job on your same type of car you have).
Testimonial: "I just changed the thermostat and did a coolant flush, that didn't fix the problem. I have an auto controlled temperature system, my dad changed the controller couple months ago and he didn't install it correctly. If I set the temperature to 75 degrees, I get cooled air. I have to raise it to 85 or 90 to get decent warm air but not hot like it used to be. No matter how long I keep the car on, the temp gauge is never in the middle, it is slightly lower. What do you think is the problem?"
Please let me know, the weather is getting colder and I want to fix the heat issue.

I just found that fu**er under the car, follow the top raditor hose to it.
