After you check the things that other folks have mentioned one more
thought.  I have had problems with aftermarket tow hitch wiring systems
messing up the brake lights in the rear.  Basically folks splice in
these two hitch wiring deals and they have a control box that seems to
go bad over time.  Maybe it is something that the PO did and you don't
even know about it.  However if you have a tow hitch wiring plug and you
have checked other things and coming up empty I would suspect that.
Just a thought.
