What could cause a windstar to have no heat?

Answer 1

A no heat issue can be caused by 1 or more faults for any vehicle, you first must isolate the trouble. Knowing that your heat derives from the circulation of engine coolant throughout the HVAC system, first determine if you have a coolant leak or not. Check your reserve tank levels if it is extremely low or completely empty add sufficient amount of coolant mixture ( coolant mixed with water ) to the correct levels run the engine to help purge air then add more if needed. if heat begins to work inside your vehicle then you must locate where the leak is and correct that issue. If your trouble is not from low coolant and you have a sufficient amount then look elsewhere ... making sure the radio is off and you can block out all other ambient noises pay close attention to the area of the radio in the windstar with the vehicle running first turn off the recirculation fan and place the temp dial on coldest. move the recirculation fan setting to the first running mark ( 1 ) then move the temp dial all the way hot, do you notice a slam noise or a clicking noise ? the slam ( shut ) noise is normal, sounds that of you cupping your hands the closing them together firmly yet soft. if the noise is that of clicking this is abnormal and the resolution would be to replace the heater control valve located behind the radio cost is apx 50 USD from the dealership and takes about 10 minutes to replace. However you will need the Ford factory radio removal tool to pull the radio out to get to this location. The ford factory radio removal tool cost apx 5 USD can cal be brought from radio or car electric shops even at best buy.
