How do you fix the heater in a 2000 Ford Windstar if it gives no heat just cold air?

Answer 1

I had the same problem on my 2001 windstar , behind the radio there is a part called blend door actuator , got it at advance autoparts , about 60 dollars , took about 30 minutes to change out , plastic gears were stripped , that's what makes clicking sound , now my heat works great, Jerry from Orlando

If it's not the actuator motor, the actual blend door may be broken. This is a very common problem in the Windstars. Typically the dash must be disassembled and the plenum box removed to access the blend door. I tried another method with the heatertreater. It involved removing the glovebox and making an incision in the plenum box to replace the blend door. It saves a lot of time, check your actuator motor to see if it has the stripped gear issue first.
