Of course you mean the steps won't retract when they are supposed to; as in the switch is in retract-when-door-closes (a position I NEVER use), or the ignition is on. My steps are controlled by a magnet switch on the screen door, in the middle at the top. It looks like a small white rectangle, with another small white rectangle mounted on the door jam just opposite it. Actually, the one on the screen door is the magnet, the one on the door jam is the switch. As the magnet gets close to the switch, it pulls the switch closed. It's gotta get pretty close to function. Steal a magnet from someplace and hold it near the switch on the door jam, the steps should retract if everything is set correctly.
