To Doug;
Is the step module (outside)under the steps? I did notice a metal box about 3x5x1 that does have wires coming from it, & it is right next to the motor with the large gear that turns when the steps move in or out.
When I took the coach to the RV repair shops, no one even mentioned that box so I did not think it was something that had to do with this problem!!
I did take off the cover for the on / off switch for the steps, on the side of the cabinet, near the door. lightly sprayed the connections with a electrical spray cleaner, then put wires back together and made sure all connections were very tight.
This action still did not solve the problem, so my next move is the outside control module you mentioned, ( that metal box)! Thanks again for your input, F.N.L
