I had that happen once and my windshield was covered with radiator coolant from a leak in the heater core.

Two things can cause this. First check the air plenum drain. Open the hood and on the passenger side the is a rubber tube from the firewall that points down. You will have to get under the vehicle to clean it out. Use wire to clean it out, most times it is clear close to the bottom. I have had to blow it out some times with air to clear it. Once you clear it, water starts coming out.. You don't wont to remove the tube because water could start dripping inside. Next problem would be a hole in the heater core. It can be removed with out the dash coming out. But you do need a manual for this. There is still lots of parts and screws to remove to get it out.

SOURCE: PROBLEM WHEN SELECTING THE DIRECTION FOR THE AIR

Sounds like you have a supply vacuum problem. When you lose supply vacuum to the control head it defaults to defrost.

SOURCE: Blower air just through defroster vents, not front vents

The problem is that the plastic lines that the air flows through get frail and cracks and breaks.What happens is when the hose breaks you loose vacuum and the system reverts to defrost mode.You should be able to see it from under the hood on the passengers side.You will have to find the area that is broken and then go to the parts store and get some rubber hose that will fit over the plastic hose.Take a piece of the plastic hose with you so you can get the right size hose to fit over it.This just happened to my 97 Astro van.I found the broken hose and repaired it with the rubber line and is working normal now.Hope this helps.Let me know what you find out.Good luck.

SOURCE: 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.

You didn't specify what type of vehicle.
If you have very poor air flow out the vents, later model vehicles have a hepa filter or cabin filter in line form the blower motor to the vents. It can be plugged quite easily and drastically cuts down the air blown into the vehicle. Check to see if they are plugged. Secondly, Check your coolant level in the rad and reservoir. If the windows fog up when cold and air flow is good it could indicate a leaking heater core. Check the passenger side floor for signs of coolant again I don't know the type of vehicle, some heater cores are located at the firewall under the hood.

Heater/defrost does not change position. windows fog, fan motor running as should just will not let air into cabin.


get the cabin air filter of ur endeavor changed by following method.
Procedure to Remove the Old Cabin Filter First off, you need to open the glove compartment; you'll see two screws on top of the glove compartment and two at the bottom of it.

Remove each one of them one by one with the help of a Phillips screwdriver, and then unhook the stop bar which you can find on the right side of the glove compartment .

Next, pull the glove compartment out - while pulling the glove compartment out we disconnect the light wire .

Now, you should be able to see two tabs on both sides of the cabin filter which we press towards the middle of the compartment and then we remove the cabin filter cover . After this, slide the filter out of the housing .

Putting the New Filter In Place Now, you can easily insert the new filter in the filter housing making sure the "up" arrow printed on the filter points towards the roof of the Endeavor and then we replace the cabin filter cover.

Next, insert the glove compartment back into the dash and while it is half way through you need to reconnect the light wire.

Finally, reconnect the stop bar over the hook and finally replace the four screws to hold the glove compartment firmly in place. And, that's it - you've just learned how to change cabin filter in Mitsubishi Endeavor.
