Yes, all of my problems were intermittent as well. It all depends how the wiring harness lines up after you close the deck lid. Once the wire(s) gets broken, things may fail if the harness happens to bend into the wrong position (like if you close the lid hard and fast). But if the harness bends correctly, the problem may appear to be fixed (at least temporarily).
