Thanks, Rick. Yep, I've been laying down there with a mirror too! Whole lot easier than getting up over and over.

I've been concentrating on the ground screw to the left of the panel plug... although I did loosen and tighten the one by the speedo too. I'll pay some more attention to the one you're talking about. It sure sounds just like the problem you had.

I'm not sure how to test each side of the bulb while it's still plugged in... do I need to partially disengage the bulb socket? I have a voltmeter with some small probes. Or, can I simply touch the visible trace on the surface of the printed circuit?

Thanks for the help - I'm making a big pot of chili right now but was planning on taking the column apart tonight or tomorrow. I'd much rather try what you're suggesting.
