HVAC under-dash vacuum lines question

What's up everyone, got a bit of a question here.

I began working on the A/C in the 5th again today, and when I turned on the air, I only got airflow from the defrost, not the vents on the dash. I couldn't redirect the airflow to save my life.

So I took out the panel under the driver side of the dash, and little green chunks of what used to be rubber fell out, and I noticed that the color-coded vacuum lines were all hanging, disconnected. I'll attach 2 pictures for a reference.

I know...
