On the way home, air stopped blowing through center vents?

I had previously rigged open the center vents to empower the A/c to be more effective. While driving home tonight from Foxwoods, I switched the vents to the window defrost and footwell position as the a/c was too cold. When i switched back to the center vents, the a/c wasn't blowing through. The blower was still blowing but no air was coming through the center vents. Do the vent actuators go out this suddenly? What else could it be?

Depends on how you rigged it open. It may have returned to closed position and you'll have to re-rig it again.

Well it works again, don't know what happened. Maybe the ACC is on the blink.

If you rigged the center vents open, what does the ACC have to do with it? Or the actuator?

The center vents are fresh air vents, right? I propped open the flap to allow the a/c (or heat) to blow through the center vents. Doesn't the ACC push button controls open and close the actuators to redirect the intensity of the air flow? Otherwise I am amiss as to what happened.

Heat flows through the center vents in that car?

Hmm

Funny you should mention it, just last weekend, mine seemed to close too after multiple years of being lightly rigged open (explained below).
To fix, it was just a matter of popping the glove compartment out after removing the two piece fasteners and carefully letting the glovebox light through in order to gain access.

I used my right hand reaching through to carefully remove the right half of the rubber vent tube to be able to reach in and flip down the vent.

I turned the engine on while I held the vent flap open and with a finger flick, nudged the center actuator arm so it sits above the open vent flap.
The end of the actuator arm has a wider end, and if it's over the open flap, it seems to just slide over the open vent flap.
I turned off and on the engine multiple times with my hand in there to make sure the actuator arm did indeed sail over without closing the flap.

Normally/from the factory, the open flap top center has a matching hole/circle where the actuator arm connects via pin. On my car, that pod is on the weak side, but not enough trouble to justify replacing it, as it's a bear to do from just about all accounts I've been able to find here.
If I need to adjust that flap, I just do it manually and it seems to hold in the desired position for at least a year. The fix I do takes about 10 min. max.
As my a/c works, and it's a window heavy/sunlight streaming TD, the center cooling is appreciated.
