I was driving on the freeway, and tried to use my windshield wipers, and they would not work, nor would the blinkers, windows, or sunroof. I tried the headlights, and they came on. After turning the headlights off, the functions mentioned above did work. It happened two days ago, and hasn't happened since. What should I do?

If it is not occuring at this time it will be very difficult to diagnose. This may have been a glitch with for front SAM (signal acquisition module) however without the condition being able to be duplicated this will be nearly impossible to prove. If it begins to occur again pay attention to all circumstances around the fault. How long have you been driving. What temp is the egine operating. Do any warnings come on. How fast are you going. IS it cold or hot outside. These questions may help in furthering the diagnosis even if you cannot duplicate at this time.
