I thought at first I had a relay bad, my fuel gauge odometer would go out then back on, usually at low speeds. I attributed it to low voltage and higher amps. When I was at highway speed it never happened, as soon as we slowed down it would happen. So the odometer, compass, fuel gauge and the ac are all affected. It tripped out the other day and never came back. Any direction would be appreciated, I did check the obvious fuses and relays.
