    We also noticed when depressing the horn to actuate it in the straight position, there is hardly any movement. When in a rotated position, there is a definite actuating movement or depression of the horn. There something happening when it's a straight position, the horn is being prevented from making contact so the horn will work.
    Thoughts?

    Do you mean the angle of the steering wheel when you say straight, etc.?

    My guess is the clockspring. The spiral cord or one of the electrical connections is loose connecting the clockspring. The clockspring allows the horn and other electrical buttons on the steering wheel to work at any angle of a steering wheel turn while keeping the airbag properly connected.

    If Toyota uses a clockspring for the horn, then you need a new one.

    If Toyota uses a finger style contact and a commutator like contact(like automakers used for years) then that would explain the dead spot.

    On the other hand, the horn may have grease or carbon build up on the following contact finger.

    Either way, the steering wheel will most likely have to be removed. Can you do it yourself? If you disconnect the battery, if you are comfortable doing it. If not, take it to the dealership.
