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.

I have a 2011 Chevrolet Equinox LTZ and my question involves the heating/ AC unit. The air flow seems to be very strong through the Defroster but for the dash vents and the floor it seems to be much s


Defrost has been stronger on all types. Just the way plenums are made. Clear that wind shield first. As long as you have plenty of heat to keep the cabin area warm to hot, it's OK. I wouldn't woory about it.

AC is only blowing through the defrost vents in the dashboard?


I think your problem is the head unit that selects where the air comes out ie. Face, floor, defrost, or hi-level face and floor. If that's not working then it will not let you switch location that you want the air to come out.

The ac on my 1998 ford ranger only blows out the defrost vent and floor vent. How do I fix it?


Almost sounds like the actuators are inop. depending on which style you have, some are electrical motors and some are vacuum. These control the mode doors which move to deflect air to various vents.

There is a blend door acuator which moves when u change your settings. Its a electric motor. Down under dash, Will need a mech and a heating and cooling diagram to find where the motor is,

A/C blows from defrost and floor vents, nothing from dash vents.


the switch where you turn it to blowing at your head is probably out. you will need to replace the switch control where your defrost, foot, head etc. what make, model, year is your vehicle?

Poor air flow from floor vents or when multiple vents choosen


There has to be something blocking the output somewhere. Check where vents come out to see if something has fallen down to block them.

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.
