Our ac attaching nipple under passenger side broken off water leaking

What is your question?

We are being told we somehow kicked and broke off the nipple underneath passenger side of our cayenne- is this even possible in that i don’t even know where it is? isnt it protected by a cover? Never the less is it an expensive repair to replace this assembly ? Thanks.

What makes this problem better or worse?

When ac running water on floor board
