Fixing A/C Vent

Hello,

I'm new here and I was hoping someone could help me with an issue on my 1998 Acura TL 3.2.

My A/C vent on the center console passenger side is no longer stuck to the dash so you can use the vent because it fell back about an inch. Can someone point me to a fix? I know I may need to pull the dash to reattach the vent but I don't have a clue how so pictures or tutorials would really help.

Thanks!
