gotta roll the window down.
pull the window weather stripping out, but not off competly, leave it attached near the mirror.
then you will see 2/3 screws for the b pillar, take those out, and the 4-5 for the window trim at the top.
take the screw off on the back corner.

pull up and preseto
its out.

reverse to get it back in.
