Is there a reason why your cruise control and your horn stopped working at the same time and could it be related to the airbag recall on your Honda Odyssey Van airbag?

Answer 1

There is a device under the airbag called a clock spring. This coiled tape contains electrical conductors, and allows for rotation of the steering wheel without twisting the conductors. If this tape gets kinked or broken, that would explain why your horn and cruise control both stopped working at the same time (assuming steering wheel mounted cruise control). To check or replace the clock spring, the air bag must be removed on most models, which can be dangerous unless the air bag is properly disabled.
