Hey guys. I have a 2004 EB 5.4. Air blows cold, temp not an issue. Strange thing. When I hit auto, air used to blow right out into your face. Now it blows half out to your face and half out of the top like defrost. If I turn it off and on af few times, goes back to hitting you in the face. Then when I start driving, it goes back to half and half. If I sit in the car I can get it to stay on blowing in your face. If I scroll through the different modes of where the air comes out, it seems on all of them half the air comes out by the front glass like defrost???

Any help would be appreciated!!

Sounds like a vacuum leak check under the hood Around The Battery area

Oh man. No clue. I see vacuum lines but can not tell if anything is leaking. Any suggestions? Thanks.
