Rear window defroster isn't working. I have checked the relay and fuse and have 12V at both sides of the fuse. I don't have any voltage at connector to grid. I do have continuity from the grid to ground. Problem is somewhere in wiring from fuse to grid. Where can I find the connector for the wiring? I assume one is burnt from what I have seen on the internet about other car. It is a 2007 G5 GT. Thanks.
