I'm new to this site can't figure out where to post this and how to post. So I'll just ask anyway the 2002 Audi A4 1.8 L I have all of a sudden there's no tail light running lights, license plate light , dash lights, windshield wipers, blinkers , Orr high beams. All fuses are good relays are good replace the ECM and even replaced the steering column with new blinker switch cruise control and wiper switch. And I replace the hazard switch as well. I don't get any codes that come up that just can't figure it out neither can the local auto garage does anyone have any ideas?
