Have you used a test light to verify power ot the interior fuse panel? These circuits dont share very much other than getting their power from the same place

Thanks for your reply. I looked under the hood today and noticed a plastic wire plug connector that leads to a black box on the fireall melted. The plug connected 4 wires that lead from that black box towards the front of the engine. The wire colors were black, two aqua wires, one with a yellow strip and the other aqua wire with a black strip, and a creamish color wire. I cut the plug off and reconnected the wires but did not get any resolution. Could this be the black box? Many other wires lead to the black box.
