Headlight Switch problems of the 2012 Jeep Liberty

Had vehicle at dealership about 3 weeks prior for a heavy burning smell inside and out side of vehicle. Smelled like burnt wiring. Was told by dealer it was a sticker on the exhaust pipe. Was told it was fine and might smell it for a short time. . Smell is still there and last night vehicle was on snow covered road with on coming traffic and the headlights and all interior lights were lost. . Headlight switch was moved back and fourth from auto, on, and off numerous times till lights came back on and it did it again on the way home in the morning. Going to take it back to dealer about an hour away for the second time. . Not sure why Chrysler doesnt take time to look at things properly and listen to the owners. A sticker burning off doesnt smell like burnt wiring. .
