Unknown Driver error in DIC display. Door locks, windows, radio, ac, instrument panel goin nuts, key fab, etc all going crazy or not working.
Found a quick fix on the instrument cluster harness. After about 4 hours of testing, I finally located a wire that at least fixed the immediate issue. It is black with white stripe on back of instrument listed. Hope this helps someone.
