It sounds to me like the Combination Switch is toast. The combo switch
activates the turn signals and the High Beams.
In order to properly diagnose the problem, the steering wheel will need to
come off. There is a slim chance that the combo switch can be repaired, but
the odds are better that it will have to be replaced.
