My husband and I were doing some maintenance on the camper. I had opened it some just to be able to open the side door a little. He came out and said he needed to get in and get something so he needed to open it up more---went and hit the button for it to go up and there was nothing. The motor still works on going down but nothing for going up. I thought it was the limits switch so I tried to raise the limits and...nothing. I know it is not the battery or fuse because it runs to go down. I also took the batteries off and to the auto shop to have them tested and they checked out. I thought it was either the relay or the power limits switch itself. I took to the dealership today and they advised that you can't just replace the relay or limit switch by itself...you have to replace the whole power lift system. I find this odd because I have found the parts online. My question is....have any of you replaced the limits switch or relay on your Carefree PowerWinch? Is it difficult? Any special parts.
