My dash lights and taillights won't come on with my head lights anymore. It is possible to get them both on at the same time, but very difficult, and requires that the switch be in just the right position. With that said, I got a new head light switch, figuring that that was the problem. Just finished installing it, and nope, that doesn't do it. Has anyone had this happen before? Or does anyone have any thoughts on what it might be?
