With key in ACC, all accessories and lights are fine. In ON (not start), all accessories go dim and clicks come from under the hood, like a solenoid opening and closing every second or two. In START, it clicks once like the starter is trying to engage, all the accessory lights go out, and nothing happens. Something like this happened once before, and a friend mentioned that sometimes that type of starter gets frozen up; hitting it with a hammer will break it loose. Worked last time, but not this time. Thanks.
