Yes I would also agree with the Multi-function switch. There was a thing on the ranger site and it was called the "ghost wiper" or something. Basically like if you were driving down the road, the wipers would turn on automatically. Now the only fix to this, besides buying a new switch, was to take the switch apart. They said, that the build of dust and whatever else happens to make itself in there, would make it ghostly work by itself or sometimes not work at all. So I would say, if your feeling adventurous to take it apart or just buy a new switch. Its pretty easy to remove, just remember to disconnect your battery to take away the chance of the airbag braking your nose or whatever. Theres like 3 screws that hold the steering column cover on. If I remember, I believe there to be one bolt holding the switch in place. And a wiring connect. Its pretty easy.
