Yes, you will have to remove the inside door trim. To do this: Remove the silver plastic cover on the door pull. And remove the small black plastic cover from behind the door handle. There will be 3 screws behind those covers mentioned. Unscrew them. Grab the bottom of the door trim and pull until it comes free. Unplug the window switch and set aside the trim. The plug for the mirror power should be visible now. Hope that helps
