how 2 remove vents? 93civic

I need to know how to remove the air vents in the dash on a 93 civic. Particularly the one on the passenger side. I dont want to just yank on it because I don't want to break it. Are there clips? How many?Where? how do I go about removing it?
Thanks in advance.

Remove them CAREFULLY with a little screwdriver and your set .. just have to be patient and go little by little.


Horn out.
