High beams non-functional

[JoelS]

I was replacing my cruise control amp a few weeks ago with a used one (still doesn't work, though...) and upon reinstalling the panel under the steering wheel, my high beams no longer work. The low beams are fine and the highs worked until the reinstall. Obviously, I've screwed something up, but has anyone a suggestion of where to start. I'm assuming the switch...but is there an obvious point where they fail?

Thanks to all,

Joel
