Question about 1999 Ford Windstar
I've changed the thermostat twice is not leaking coolant both houses are heating up on the heater core it is not overheating or under heating
If you have a knock or clicking noise behind the radio, it is the blend motor. The blend door is spring loaded and the gears in the blend motor are "stripped". The door is spring loaded so that the door is closed to the heater core. About 2 hours to replace and a lot of bending and stretching. You don't have to remove the dash, but all of the trim, radio, and controls will need to come out.

For the heater blowing cold air it could be the air dam not working, heating system may be plugged, thermostat sticking and not operating like it should. Do the easy things first, then get to the heater core and air dam if necessary cause to look at these items you would have to take the whole dash assembly apart. As for the van running rough and the smell of coolant coming out of the exhaust, that is a classic sign that the head gasket may be going, ford windstar are long known for their headgaskets blowing.
Hope this helps

You have a heater blend door problem, this is the door that diverts air either to the heater core or the AC evaporator to provide either hot, cold or a mixture of the two, it blends the air, if it fails you can't control the heater or the AC temp depending on which way it fails. In your case it failed with the heater core closed to the air being blown through the system.
