SOURCE: 2005 explorer only blows ac out defrost vents why?

Defrost is the default position, The control head is most likely electronic on this model, the actuators that switch the modes are little electric motors. There was an issue with the plastic doors that direct airflow, they would break and jamb. If the control head were to be the older style that uses vacuum then I would say that you have lost vacuum to the inside of the vehicle. If this is the case look for a broken vacuum hose coming to or through the firewall, ususlly on the passenger side under the hood close to the HVAC pipes/lines in the firewall.

that clicking noise you hear is likely a relay in the fuse panel that needs to be replaced. the easiest way to find out which relay it is would be to put you finger on each relay as you actuate the device not working. once you locate the clicking relay replace it . to reset the computer just unhook the battery for about ten minutes. if you have an anti theft radio make sure you know the code for it and how to enter it before you unhook the battery.

2002 ford explorer air only blows through dash vents will not switch to floor or defrost vents

This sounds like an actuator. There is usually several (three or four) on different vehicles. There will be at least one that directs the air to different locations such as defrost. You also may have a defective selector switch. I would check this before I changed the actuator or blend door. If the blend door is defective, this usually calls for totally removing the entire dash panel and usually requires several hours work. If you have to have a repair shop do this it can be very expensive.

1998 Dodge Stratus - Air conditioning is blowing through the defrost vents

Vacuum controls this circuit and leaks will cause blend air door to default to defrost. Check for bad check valve or hose leaks under hood first as these are the easy ones to get at and under hood heat causes deterioration.

    I have a 2005 Ford Focus. My vent distribution knob turns freely but does not change air direction. It remains blowing from the defrost vents. I pooped off the face around the knobs and stereo to look...

    The part you're describing is the blend door actuator. It diverts air through the different ports, (floor, vent, defrost, mix). The good news is depending on what you need (new lever or new blend door) the price runs about $30-40. As far as ease of installation, it sounds like you have unobstructed access so replacing it shouldn't be too difficult.

    Ac is blowing out of defrosterandnot panels in the dash. Air is cool cold air will blow out of rear seat panel/vent 1998 ford explored

    The most common cause is a bad blend door actuator which controls air flow throughout the cabin. When air flow only flows from 1 section (either floor, vent, or defrost) it's an indication that the blend door actuator is either stuck or broken.

    I have a 2007 ford explorer, all of a sudden, the ac blows only through the defroster,and at my feet. It will not blow through the front vents. The ac blows cold.

    the blend door actuator is bad. there about 70 dollars at ford. make sure you hook up the actuator and put the control on defrost before you bolt it on the air box or you will brake the blend door.
