Hello. I have no heat on my 2000 windstar. Already replaced heater core, thermostat, flished radiator, and replaced bleand door actuator. the blend door opened when I teted it. Please help and thank you in advance.
So the blend door opens? Does the fan motor blow? Are both heater hoses hot? That would indicate the coolant is circulating through the core.

My 99 windstar did this too. It was the blend door that the actuator motor goes into was broke. When you pull the actuator out look into the hole and see if you see a d shape piece coming out of the box if it is not d shape it is broke check out this site great photos

All I did with my 1999 blazer is pull the a/c fuses from under the hood and heat blows just fine.
good luck

Blend air door may be stuck. I removed a pencil from a heater box before. It had fallen from the dash, down through the defrost vents and jamed the door.

You might have to purge the coolent system cause when you change stuff like that you normally have to bleed the the colent system. So what you have to do is run the car untill your temp gets to 195 degrees the cut the car off and let the coolent drain down and then refill and geep doing that untill you have heat.

You hot air comes from the water circulated through the heater core. It is like a miniture radiator with water flowing thru it constantly. So by opening the "Blend Door" you are permitting so much of this hot air to pass thru.
Seems like for some reason your heater core is plugged up. Just like a radiator can be. So water may be passing through your heater core but not passing through fully. Your heater core gets hot from water passing throught it from the engine. Then your doors open up, in proportion to how much air is permitted to pass over the heater core.
Suggest to remove the heater core and replace it. Seems the blend doors are working properly but again, if you have a non working heater core then no air can pass over the "Hot Core" for you to recieve hot air.
If you are not mechanically inclined, then go to a local parts store and you can buy a car manual, such as Chilton's or Hane's Car manuals, for your year and make to show you how to replace it. Then you can also have it for any other problems that may arise.
