I'm not sure about your 79 but on my 82 the step is vacuum operated. It will not retract unless the engine is running and the door is closed. There is a button switch in the forward door jam that operates an electric solenoid valve the allows engine vacuum to retract the step. Check the vacuum tubing and operation of the solenoid valve. On my coach the valve is under/behind the step. That being said many have replaced the vacuum set-up with an electric operated step.
I hope this helps.
