Anyone have a problem with their headlights (and taillights, instrument, etc.) staying on whenever the ignition is on? I can turn them off manually using the O on the auto switch. The obvious answer is a bad sensor, but I'm not sure how to check it.

And a big thanks to the board for all this great info. :ro) This is my first official post, but I've been lurking for a while.
