Iggy, just reminder, that if the magnet on screen door does not line up correctly with the magnet mounted to door frame, steps will not work even with engine start. Just had that happen in AZ, Yesterday. Leave main door open and try engine start, if no action pull on screen and make sure magnets line up, mine out of alignment at bottom.
