Sounds like a defective "mother board" in the receiver unit. These units are IMHO infamous for blowing fuses and I've never had all functions on my Wildcat MAXX functional with BOTH the remote and the toggle switches at the same time. One or the other works but at least one function only works with the remote OR toggle switch. At this time, it just happens to be the levelers, they work on the remote, however, the outside toggle switches are not functional.
