Run a flat blade screwdriver along the bottom edge to find each of 2 recessed areas to slip the blade into where you can twist and pry. They're each about 1.5 inches from the left and right edges. Once you have it free then pull out and up at the bottom to clear the face panel from the upper lip. There is no need to pull out anywhere but the bottom once it snaps free after using a screwdriver as a pry tool. The wiring connector has a tab that you need to get a fingernail under. The tab might be on the side hidden from view until you twist the harness to see it if necessary. Pull apart the electrical harness connector once the tab is free. The face panel can then be set aside.
