The PO of my 2006 just pulled a wire on the switch. Which one, I'm not sure. Now, the steps always open when you open the door, and they always close when you turn the ignition key to "on" position. For the sake of safety (his sister stepped out once with no steps there), he only wanted them to retract under conditions that involved the ignition key. So, when I park the motorhome, and want the steps retracted, I just climb in and turn on the key real quick and get the job done.
