I'm fairly sure it is the switch. I went to Camping World to see if they might have a switch. The gentleman who helped me brought me a switch that said it is for a slide but it looked just like this one with the four post on the back. He told me it should work. Put it in and now it is as if there is no power at all going the the footrest motor. Anyone have a suggestion? I have power to everything else on the seat. I put the wires back just as they were on the original one. Is there a fuse somewhere just for the footrest? Does anyone know where I could go to get an actual switch for the chair? Any suggestions would be appreciated.
