Need technical manual description or good experience

[iwillnc]

I was riding in my friends H3 and i was adjusting the air vent and it broke after the 3rd time doing it, I feel kinda responsible even though it was gonna happen if it was that weak.

Anyhoo I ordered a new part to replace it with

25816720
GRILLE
(gmpartsdirect)

(dunno why it says grille, picture and writing shows it as air vent)


And I would like to know how to remove the passenger side air vent closest to the window in order to replace it.



p.s. does the H3's sunroof not have a drain on the passenger front corner?
