Appears that there are two bolts that you can access, after removing the radio, that hold the vents. From compnine.com, and I remember seeing those screws when I replaced my radio.
I am planning on taking my center vent trim plate off of my trailblazer. I tried pulling it off but I did not want to break it? Looking at the exploded view it looks like that is what I have to do. Am I correct?
