This guide instructs on removing the driver side door panel - removal should also be the same for the passenger side panel
Tools needed: Phillips screw driver
First start off by rolling your window down to avoid scratching.
Next open your door all the way you should be able to see two quarter sized plastic covers. Remove covers to expose the screws.
Move to the bottom of the door and look for two separate screws. Unscrew those.
Look around the armrest area and look for a hole that has a screw buried inside.
Now the tricky part is to take the small panel off that covers the screw beneath. It is behind the door handle. Push with some slight force - might be stubborn but it does come off. Push in and towards the rear of the car.Unscrew that and you should be ready to remove the door panel.
Removing the small separate panel in front of your door's mirror is up to you.
Now slowly work your fingers between the door and the panel and unsnap each "clip". You should than be able to pull your panel up and out.
