SOURCE: 2004 Ford Crown Victoria no air flow through main air vents

Chances are the electronic/digital HVAC control unit is bad. This same problem happened to me and I had to replace the entire unit. The dealer wanted to charge $800 for just the part! After I freaked out on them, they found a used one for less than half. Sorry, but there's no easy fix here.

SOURCE: No dashboard heat output

The climate control was poorly designed on these cars.

There is only heat on the floor and defrost settings, due to the layout of the ductwork.

SOURCE: Warm air from dash vents but cool air from defrost

The system just needs to get all the air pockets out if you switched everything like you said look around where the radiator hose meets where you put the thermostat in, there should be something on the lines of a little nipple with a 8 mm bolt on it i will have to pull up the exact setup of your Taurus but its the same general concept your car is fine you just have a big air pocket , what else you can do is while its cold right now and the car isnt running is to go take the radiator cap off the radiator and see if the antifreeze is low now that the car has cold down since you last ran it. If so feel it up top it off in the radiator and it might hurp it self and remove the air pocket all on its own... If you need any more help feel free im always on here id be glad to help more in detail once you try that and look under the hood for the bleeder ( the thing with the nipple on it) Also if you could please rate me i would greatly appreciate it.

Thanks,
Steve

SOURCE: cannot redirect air flow from defrosters to dash

defrost is the default position when broke. so the most common problem on these it the actuator motor that turn the door inside to redirect the air flow. but the head unit also goes bad to. so this will have to be checked eclectically by a shop to make sure that is the issue's

On my 2005 Ford Taurus the air conditioning is coming out the defrost vents.


There is a flapper or trap door in the dash board that diverts air flow to various vents, defrost, floor, face, etc. If that stops working it will get stuck in the default position which is usually the defrost vents.

If you have a vacuum operated system you can check the vacuum hose for the system in the engine compartment for integrity. If that is ok then you have to get to the vacuum switch in the dashboard and probably replace it due to leaking vacuum - labor intensive and not cheap.

Any time the dashboard has to be removed you are in trouble money wise.

Poor air flow through defroster vents


Got kids? Years ago, mine loaded the defroster ducts with toys, candy, etc.
Otherwise, please create another post and identify the year, make and model vehicle you're talking about before posting your question.

Dash air flow problem


This could be a couple of different things. It could be the control head itself, an actuator inside the dash, or the blend door, or the blend door motor itself. The first thing I would do is turn the air on, put my ear close to a vent and move the switches on the control from floor to dash to vent. if you can hear any clicking at all you know it is not the control head. In that case, you mnay have to take the dash apart to go any further, and if youve never done this before I would not recommend it.
