I am not familiar with the Vegas wiring specifics, but you could check the DC fuses in the house fuse panel usually near the converter unit. (Sometimes located at the end of the bed or similar). There might be a 30 amp fuse labelled slides. I am not sure if all coach slide controllers (including the drop down bed) are fed from this fuse. If your other slide(s), if equipped, are working, then likely not that fuse. There might be an in line fuse on the power feed wire to the controller.....but others may know more details about where that might be located.
