Which ever connection you moved or adjusted 3 months ago would be a good place to start. I would disconnect any electrical connections, inspect for corrosion, and put in a small amount of dialectic grease. Then check any ground connections by removing bolts/screws, make sure good clean metal to metal connections and reinstall. Might be loose and binding hinge bolts.
I also would see if the brand has wiring diagrams with descriptions and trouble shooting that can be downloaded. I have the Kwikee steps and my "packet" has that brochure.
