I need to replace side mirror on the passenger side,but not sure how to remove door panal to getto the plug

First roll down the window and remove the inside mirror cover the remove the push pins in the back of the door panel ( push the center in to the 1st click then remove the pin from the door panel . With the pin out of the door panel push the center pin back out of the push pin retainer so it will be ready to go back in)Then remove the screw cover behind the door pull (just pops out) remove the 2 screws . Use a door tirm tool to release the push pin retainers that hold the trim to the door and lift the door panel up and off the top edge of the door . disconnect the elec connectors.
