no heat could be a number of things, you could have a bad thermostat or a crack in the block. or even just a bubble in one of the lines, (coolant) better hope its the thermostat
Yes, If the thermostat isn't working, It cant tell the heat to come on. Thermostat is the brain of a heating & cooling system. Most likely the thermostat itself has worn out and does need to be replaced. You can get another digital one or you can change to an older style if you so desire.
That's probably a good bet. Thermostats are relatively cheap and if you have a concern such as the one you describe, you should just change the thermostat.

if your thermostat was bad your engine will over heat but it has nothing to do with the fan,fans are driven by a diffrent mechanism. try checking your thermostatic switch/ heat sensitive switch or sensor, located somewhere in the cooling system(radiator,engine block or thermostat housing) which is the one that tells the fan when to come on.(only electric fans)it may be faulty wiring
You might need a new heating coil.
Take off the thermostat housing which is located right where the top radiator hose clamps to the motor. thermostat will come right out. be sure to install the new one in the same way you take the old one out.
check the thermostat see if there is one, if there is it may be stuck open.
The temperature sensor should be located close to the thermostat and has one wire going to it.
In the "Related Questions" below, one writer offered:How you determine its the heater actuator versus a stuck thermostat is simple. Most Windstars ( I have an 02) have 2 zones. The front zone will only blow cold air, but switch to the rear and turn on heat. If hot air flows, your thermostat is good.
The air cleaner will have to be removed to gain access to the thermostat. the thermostat is housed in the water inlet at the engine. Remove the housing and the thermostat will come out. Clean the old gasket material from the housing, replace the thermostat in the same direction as the old one, and reassemble the housing and air cleaner.
Chances are it needs a new thermostat. It probably has a failsafe one in it which is a good thing. What it does is allow coolant to flow from the engine block to the radiator but because the thermostat is not working there is no pressure built up which gives heat through the heater core. Make sure you get the correct one and get a failsafe one. These ones make sure that the block doesn't crack when it is extremely cold and also overheat and crack because of extreme heat.
