Air Condition Blows Out Every Vent

My '98 3800 Intrigue does not allow me to control the air flow on my AC. It blows air out of every single vent and does not all me to change the modes. Can any one think of anything that can solve this. I live in Texas...

I'm having a similar problem with the AC. Pull out the glove box and the plastic cover behind the glove box so you can see all the plastic tubes that control the HVAC guts. Look for one or more that might have come loose or are split or frayed. It looks like there are 2(that I can see so far) diaphragms that push and pull levers to change the flow of air.

I have pictures which may or may not help you in your quest!

The air box closed to accept outside air only.

The air box open for recirculate mode.

One of the diaphragms, this one happens to open and close the panel for the pictures listed above.

What a typical air routing hose will look like.

Thanks, I appreciate it. Did this solve your problem?

I haven't really figured anything out yet except what I suspected before I took everything apart, that the door to stop the out side air does open on the least bit of acceleration. I read this post which sounds promising:

I haven't looked yet but it's my next step. I'm not sure if our problems are the same or not. I'll post back when I have looked at my Intrigue again.
