Re: running light's keep blowing fuse!
It sounds like you're heading in the right direction. Look for a pinch or a rub through on the wire insulation. I don't know if your car has the push-in or twist-in bulbs, but pull them out and see what happens. I know with the twist-in bulbs sometimes the glass portion breaks loose and turns in the brass base.
