    i really dont understand what you said about the knob because mine is a lever u move from right to left but i did check the thermostat will i tried but when i found out where it was i did a doubletake (why put it in the spot where there is no room) so i also noticed the fluid is dirty so i think i will have it flushed in the morning. please tell me if the thermostat is behind the top hose behind a plate on the engine. thats what i was told. anny comments all would be appreciated.

I have a 99 ford also. the same thing happened to me. this is a few things i did to solve the problem.... my knob to turn from heat to cool was stripped out. i glued it and it worked for awhile. after that it did the same thing again. then i found out that my thermostat was bad and was not letting the fluid flow thur the heater core. after fixing that and adding the fluid to the max i have not had any other problems with it.... hope this helps you.... try the knob first.....

    mine had the the knob that you turn. i understand that some have both kinds. does your car have a resavore tank on it? if so putting water in it to fill the rest of the motor with water does not work always. things you could also try.... pinch top hose almost closed and rev up motor. if you feel water going thu your hand the water pump and radiator is ok. you may also have an air bubble in the motor somewhere thats causing this problem also. also if you notice a leak but no water anywhere it could be a leak it to the manifold. the is a recall item from ford. your hose that connects to the top of your motor is where the thermostat is. becareful taking it out because some of them have a metal washer that if not broken can be used again. to get rid of water bubble you need to fill up the motor with water when you have the thermostat out. fill it all the way up. then take top hose off the radiator and fill it up with water also, then fill up the radiator up where you took the hose off. put hose back on so that water is in every part of the system, even the overflo tank if you have one. i dont think it is the control in the dash...unless you have a bad soidering joint on one of the connectors. this does happen in the air speed controls but not so often in the temp controls.....let me know if this helps

My 1998 Ford Explorer Defrost Heater isn't blowing any air to the defrost Is this a fuse?

If your front blower motor isn't working on any setting, could be the blower motor itself, the blower resistor, or sometimes the wire pigtail to either one could be the problem.

99 Ford Taurus, vents not working

First, check all the fuses with a test light to see if any are blown. If all fuses are good, remove the center console part the houses the HVAC controls and radio. Once removed, check for loose connection or any unplugged connectors. If all that checks out, the problem may be the control panel itself. These are problematic and prone to fail.

1996 ford windstar blowes cold air thru defrost only warm in back

For some reason this question was listed a dozen times within an hour or so.
Usually the problem is a blend door under the dash. The blend doors direct air thru the heater core and the vents.

No heat in 99 ford windstar

Check the coolant level. If it's low, what you describe will happen. There is not sufficient coolant to flow through the heater core at idle. At 60mph the water pump is spinning quickly, managing to get some coolant through the heater core, so you get heat until the rpm's drop at idle. If it is due to low level, keep an eye on it to see if it drops again, as you may have a leak.

I have a 95 Ford Windstar, with 3.8 liter fuel injected engine. The air conditioner works when I am sitting still, but when I'm going down the road it only blows warm air. What can I look at to be a...

Check the operation of your electric fan. It should come on when the ac is on or your defroster is on as well. If the fan isn't working the pressure is getting to high in the system. Causing the warm air issue. Please let me know if this helps you.

Defrost blows cold air

Sounds like you have a plenum door that is not opening when you go into defrost mode. You will have to check all your vacuum hoses and switching valves under the dash to see which one is not working. Hope this helps.
