Welcome aboard!!
Here we go!
This is the front passenger door.
The driver door is the same except the keypad. Once you have the trim removed disconnect the keypad and it will snap out. Once you see it you should be able to figure out how to remove it from the trim piece.
Make sure the window is in the fully down position. Start at the bottom, indicated by the yellow arrow and pull the weatherstripping in the direction of the red arrows. Work your way to the top of the door. It comes out & goes in pretty easy:
There are four screws holding the pillar in, indicated by the red arrows. You can't see the bottom one in the picture, but it's there! Be very careful taking the screws out, you don't want to drop them in the door. Ask me how I know.
Maybe use a magnetic screwdriver:
I hope this helps out!
