AC climate system issue. (Not a dead display)

So in the past week only on certain days I have lost my ability to change zones for where my nice refreshing cold air blows on me from. It only blows out of the defrost vents. I here a fluttering noise under the dash when this happens. Any ideas? Also under the hood where all the AC hoses and such are located I feel cold air coming from inside the black box just next to what looks like the blower fan assembly. I don't believe I should be feeling that.

Sounds like a vacuum line has popped off or gotten damaged.

Follow the vacuum lines from the vacuum pump all the way to the hubs - I bet you'll find an issue along the way.

So it ended up being the grey vacuum hose that goes to the secondary solenoid in the heater hose. I'm pretty sure I accidentally unplugged it when I was installing my coolant filter kit. Thanks for the help!!

That is a common place - happened to me as well a couple of years back.
