So this was fun. A little more research on the forum and I found someone who did repair the other flap I discovered. Remove everything in the radio/climate cubby and you see the vent. Made a nice cut into stand the piece broke right out of the way. (all my photos flipped 90 degrees to the left for some reason)
Here's a shot poking my iPhone in the hole I just made looking down...
Jammed my hand in there and removed all the foam. Your hand will be all bruised and cut up but oh well. A couple layers of some industrial strength duct tape later and the flap was good. Gave it a good clean. Used some PVC cement to glue the piece I cut out back in and then finished it off with some more tape. I doubt anyone would really know what they were looking at if they ever saw it. Pretty happy with this and will be even happier no NO MORE FOAM blowing all over me and my interior.
