12v symptoms I don't understand

Could be one of these.
Look under the trailer, following the positive battery cable, to where it goes into a junction box. Somewhere in, or, near that juction box. Look for one of these circuit breakers.
Some have a reset button, some are auto reset, and some just blow like a fuse. Test, to see if 12 volt power is getting through.
The breakers are available at most auto parts stores. They come in 20, 30, 40 amp, etc.
Could this thing malfunction in such a way that would cause my symptoms? I'm puzzled because some 12v things like the exhaust fan, work but others don't...
