Door Steps Won't Come In

Well first I printed the manual for the Kwikee steps. I have an 04 and looking at the parts sheet it takes 909510000 which 90% do. All I had to worry about the color of the door switch, which mine was black. Having ordered a controller already I cut the wires going to the motor so I could use the connecter in the motor to verify what that the motor was good. By reversing the wires I could work the motor and gear box back and forth. My steps worked smoothly with the motor off so no trouble there. The Kwikee service manual lists all the parts for all of their equipment but doesn't say any thing out testing or problem solving.
