Help please

I have a 2010 Lincoln MKZ. When the headlights are set to automatic, the lighting on the radio, a/c and heat and steering wheel lights do not work. Also, the tail lights won't work or the bright lights but all work when I set the headlights on a manual setting. When I took it in to the dealership (during the day and it's very hard to see then) told me there was nothing wrong with my lights...uh wrong! Any ideas what could cause this?
