It could be the temp limiter switch and this is normally located on the passanger side behind the black panel near the floor it will look like a small box with a wire going from one end to the other and a screw on each end and a plug in the middle

    yep it is a Temp limiter switch and you may find one at a salvage yard I would just go ahead and replace it but yes you can test it by using a digital volt meter

Location of Heater Core in a 2002 Ford Taurus


There was a question in this forum as to the location of the heater core on a 2002 Ford Taurus. Since I can't find who asked, the location is behind the dash so if you want to replace it you would have to remove the dash completely. A mechanic shop will charge you for a 2 day job approximately $700 to $800.

2000 ford taurus heater not working. What can be wrong?


It sounds very much like the heater control door (inside the heater box) is sticking in one position or the other. It's intended to direct air through either the AC's evaporator or the heater core, depending upon whether you want heat or cooling.

Assuming (highly likely) that the control door is vacuum-operated, you may have a vacuum leak anywhere from the engine to the heater box inside the passenger compartment, via the heater control unit.

'94 Ford Taurus-No Heat?


Good point. Solving it will probably take more time than money.
Thermostats and heater cores do not work one day and stop the next. If your engine warms up normally and doesn't overheat, the gauge reads normally, engine is at normal operating temperature after about 10-15 minutes ...all these point to a good thermostat. It is working right and should not be a problem.
To check the heater core, wait till engine is at normal operating temperature. Turn heat setting to high, then feel both heater hoses-both should be hot. If both are hot the core is circulating coolant and is not a problem. If only one is hot (which would be the inlet hose) the core is not circulating-could be an air block or the core is plugged up and will need replacing.
If heater core and thermostat are good, then it probably is the temperature blend door in the heater case. The door actuator is probably vacuum controlled. I don't know how difficult it is to troubleshoot on your Taurus, but check if vacuum controls are working right from the dash controls, check if the blend door is stuck, is broken, or if the vacuum control is working to open and close the blend door. When you want heat, the blend door should let blower air pass across the heater core.
From the engine you will have a single vacuum hose that goes through the firewall into the dash to the heater/AC controls. There, a pod like device can rout the vacuum signal to various doors on the heater case.
Good luck.

I have a customers 2002 Ford Taurus that has a problem with very little heat to the interior. We tried simple fixes like a new thermostat and also found the cabin filter plugged. I now have good airflow...


Have you considered flushing out the cooling system?? I think if the heater core is plugged up with a film internal your not going to get efficient heat

No heat engine warm fan works on all levels directional control (defrost@floor) stuck on cold. ?temp control .


your heater core could be plugged if your anti-freeze color is a brownish colour , most likely your heater core is plugged also when you move the direction for heat control can you hear the blendoor move if you can then again your heater core may be plugged and if it is plugged flushing most likely wont fix it, if you don't hear the blendoor motor move the blendoor motor or the door may be damaged

HEATER


Check the coolant level.Feel the heater hoses going to the heater core to see if they are warm,or hot.If one of them is warm,or hot,and the other is not,remove the heater hoses,and flush the heater core out with a water hose.Bleed the coolant system,and you might want to install a new thermostat while you are at it.

2002 Ford Taurus has no heat


Look for a blocked heater hose (kinked, pinched, or collapsed), or a valve (either electrically or vacuum controlled) in the line that isn't opening. Feel both hoses when the engine is hot and set for heat. One should be hot and the other cooler when operating normally. If both are cool, then something is blocking water flow through the heater core.
