Re: 03 Nav Electrical issues
After pulling every fuse and relay to verify their operation I gave up. I disabled all of the functions via the setup menu and prepared to trade the Nav in over the weekend. As I went to button up all of the kick panels I made sure every connection going to the modules and the fuse box were snapped in tightly. The next morning Sunday everything was back to normal.
Looks like something had come loose or wasn't making proper contact. Regardless she seems to be working fine. BTW just noticed my typo the Navigator is a 2004 not a 03. With a little luck and maintenance she will be good for another 92,000 miles.
