THANK GOD I FOUND THIS THREAD!

Major props to you devilsrighthand!

Don't have time to read through it all but pics would be great if you can.

I'll sift through it but just yesterday my vent would be the only option to blow air out of the normal vents and anytime i switch to anything else (max a/c, auto, panel/floor, floor, def) it would automatically switch over to the windshield vent and that's it!

Sometimes if i go from "vent" to auto it will work for about 30sec and then you can hear that it seems like you said some sort of vac problem and BAM it reverts back to the windshield vent.

Luckily the AC still blows cold but this sux!

Edit: How do i know i don't have a "blend door" problem? Is there a protocol to follow for diagnosing?

From the other posts it's sounds like we all have the same problem to a certain degree.....i guess mine is in the intermittent stage......boo.
