Thanks for the advice. The solenoid plugs directly into the circuit board, which tells me it's got to be one of the upstream components on the board.

I'm going to sheepishly admit that I boxed up the unit this morning to send back to Audiovox for repair. I called them first, but they won't just send me a circuit board.

At this point, it's just a question of available tinker time. I'd rather spend the time finishing up the Kammback than troubleshooting the cruise unit.
