Most likely one of the ground blocks located in a few places in the wiring harness. There are also circuit connector blocks for other color wires that can give as much trouble.

No, not off the top of my head. But the grounds have solid black wires.

Check the main ground wire from the battery. There is a spade connector that can corrode and/or become loose.
