Keep changing out parts until you stumble across what's wrong ("gambling" method).

Or use a meter/test light and -find- the trouble and fix it ("pretend you know what
you're doing" method).

...your call.

Got one of those tools or a friend that's already got one of those tools?

Sign up on Autozone's website and then type in "wiring diagram" in the parts-search
window. Found them to be very accurate so far, BTW.

I would start with the wiring for the trailer lights... Possible, that one has chaffed through the out coating and shorted out, possibly burning a wire, or the wiring on trailer or truck got messed up somewhere and you burned up a wire...
