you probley have a vacume leak due to a broke or craked hose u should take it to a shop for a pressure test if u do not have a vacume tester.

seriously nothing being said about automatic defrost and defrost timer ...could be that its not going through its defrost cycle meaning its stuck on cooling cycle and creating your frost in freezer means bad defrost timer,not going into defrost mode ..old units have manual timers new refrigeraters have computer boards.try unplugging refrigerater for 24hrs open door and let defrost, then plug in, if you get refrigerator to cool that next day ...more then likely its the defroster timer

When there is a problem in the vent system it defaults to defrost setting. Check the doors & vac supply

This "flap" is the temperature blend door which directs air over & through the heater core.The "Related Questions" below are intended to help explain some of the basics of Windstar heating/cooling functions and terminology.That should help in the investigation of the specific problem on the vehicle, and ultimately leading to a fix.Start with the "Where is the heater control valve located on a Ford Windstar" question and then move on to the "What could cause a Windstar to have no heat - or not be able to adjust the temperature"

Air bubbles in the cooling systems usually means that the head gasket has gone out. As with most auto mobiles, air in the cooling system means exhaust is getting into the cooling system through a break in the head gasket. A break has probably occurred between the cylinder ring on the gasket and on the pressure stoke is passing through to the water port in the block at the top of the cylinder between the head and the cylinder indicating a break has occurred in the gasket.

The "bleeder screws" that come to mind are:Brake bleed - found at each wheel caliper / wheel cylinderEngine coolant - NOT found on a Windstar engine. Cooling system bleeding/burping is basically through just running the engine with the coolant reservoir cap off.

The way you get the Windstar through Marta is to plan ahead. Know the route that you want you to take, and try to travel during the day when traffic is not bumper to bumper.

If the problem is to help engine cooling through the direct transfer of heat out of the piping, the aluminum will be superior to the silicone piping by far. Aluminum is one of the best materials for the conduction of heat.

air will flow through across cooling tower

The coolant pump draws coolant from the radiator and circulates the coolant through coolant jackets in the engine cylinder block and the cylinder heads. The coolant is then directed back to the radiator. The system directs some coolant through hoses to the heater core in order to provide for defrost and passenger compartment heat. A surge tank connects to the cooling system. Pressurized coolant continuously flows through the surge tank and the process repeats

Could be a vacuum problem--either broken or disconnected hose or bad vacuum motor under dash or coming in through firewall Defrost is the default position for this system

When you set the control, if you chose defrost, it usually does it at the temperature you specify. So if you want heat only blowing through the windshield vents, which I believe may be the question you are asking, it varies between makes of cars. This is what to look for : defrost, fan speed, temperature. If you mean "Can a car that only has a heater ( no air conditioning ) be used to defrost?" The answer is still yes. I believe the question is missing words. It is comparable to asking "Hand, just finger work?" You might try asking again, being more specific, explaining why it is a problem.

This should answer your question. I too had this same problem on my 96 mustang and found this site useful.

The various functions are controlled by engine vacuum,defrost being the default without vacuum. Look far a damaged or loose vacuum line starting from the function switch,through the reservoir,to the engine vacuum port.

The air conditioning is a separate system from the cooling system and will not be affected by overheating, however if the overheating problem is associated with an inoperative cooling fan or a blockage in the air flow through the radiator and evaporator then the system will not cool properly.

Self cooling cools contentents down through convection.

Igneous rock is formed through the process of cooling and hardening.

I am not sure what you mean by the radiator bypass. But it sounds like you have a loss of vacuum to your AC/heater control. When you have no vacuum to the control, it defaults to defrost. There is only one vacuum supply entering the passenger compartment through a black hose under the hood on the passengers side close to the AC lines where they go through the dash. There is also a vacuum canister right there. See if you have knocked a vacuum hose off right there.

The vacuum supply line from the engine is disconnected or broken. When the vacuum supply is cut off the system defaults to the defrost mode.

Standard transformer cooling methods include; Air cooling and oil cooling.AnswerTransmission and distribution transformers are oil filled. Cooling is achieved either by natural convection yo the sides of the tank (small distribution transformers) or through cooling tubes, or by pumped circulation through external heat exchangers. The heat exchangers themselves, are cooled by natural convection, forced air draught, or water.

It is very very likely the doors are interchangeable. The 1999 through 2003 Windstars were essentially unchanged.
