I have a 2601ss, sometimes I have had to disconnect the battery lead(positive) to get my slide to work again. Also, you should have a tool about two to four feet long that you can attach to your slide motor to crank it in or out manually. Check under your camper, if it does not have a enclosed underbelly, follow the wires from the battery back, there is sometimes a fuse underneath.Good Luck!!
